TRX450ER6 Pics & Comparison

[Colby@C&DRacing]

C&D Racing returned from their 4 hr journey last night with the 06 TRX450ER. Since the return we have been busy trying to see what is changed and what will or will not work from the 04/05.

[Colby@C&DRacing]

The most noticable change would be the hood and headlight

[Colby@C&DRacing]

The headlight is much smaller than the 04/05 some what of a weight savings. (I know most of you take the headlights off anyway)

[Colby@C&DRacing]

New for 06 TRX450R would be the electric start. This feature will be a nice addition for the Cross Country Racing and for the Recreational rider.

[Colby@C&DRacing]

The front shocks appear to be the same as the 04/05 with a few minor changes. The upper threaded preload collar is now aluminum to save weight.

[Colby@C&DRacing]

The lower shock spring retainer has also changed for 06

[Colby@C&DRacing]

The rear shock length for 06 is 15 1/4" which is a 1/2" longer than the 04/05. The swingarm was lengthened 1" between the front pivot point and the linkage mount. This means that the 06 linkage won't work correctly on the 04/05.

[Colby@C&DRacing]

The A Arms off the 06 are the same length and geometry as the 04/05. The 06 has an improved spindle to help assist in steering.

[Colby@C&DRacing]

The battery is located under the left rear fender like the 400ex.

[Colby@C&DRacing]

The brackets for the battery box are welded to the subframe and are not removable like the 400ex.

[jgfarmsracer]

will be wierd to see dusty on a red machine


where's that starter at!

[Colby@C&DRacing]

The 04/05 seat (left) and the 06 seat (right) are slightly different. The 06 seat seams to have more foam along the sides under where your legs sit. It fills a gap on the new plastic.

[Colby@C&DRacing]

06 seat latch has been updated

[Colby@C&DRacing]

04/05 seat latch. The 04/05 seat will fit on the 06

[Colby@C&DRacing]

The 06 front plastic looks to be the same as the 04/05, but has some slight differences, the mounting tabs for the hood are different, so you can put the 04/05 plastic on the 06 but you will have to use the 04/05 hood.

[Colby@C&DRacing]

The rear plastic for 06 has been modified a bit. It now has airvents to allow more airflow to the airbox. The mounting points from the 04/05 rear plastic seem to be the same.

[Colby@C&DRacing]

The 06 has a snorkle which provides more airflow with the airbox lid on. This snorkle directs any debri that may get taken in to the bottom of the airbox.

[Colby@C&DRacing]

The 06 has a larger filter and the airbox measures 10 3/4" L x 7" W x 8" deep.

Measurements for the 05 airbox are 10 3/4" L x 7" W x 7 3/4" deep.

[Jersey450R]

Now this is what everyones been waiting for! Awesome so far Colby. :muscle:

[Colby@C&DRacing]

The intake opening on the 06 is 4 1/4"
The 04/05 intake opening on a UNI is 3 1/2"

[Colby@C&DRacing]

The 06 (bottom) headpipe is shaped different than the 04/05

[Colby@C&DRacing]

The stock 06 headpipe (top) is also longer than the stock 04/05 buy 3/4"

[Colby@C&DRacing]

With the 06 motor being 8mm lower in the frame 04/05 pipe fitment doesn't work we have tried 2 different 04/05 exhaust on the 06 and we are going to have to stick with the sock exhaust untill the aftermarket manufactures start building.

[Colby@C&DRacing]

The 06 transmission drain plug is on the left hand side tucked away behind the sprocket.

The 06 Transmission holds .72 US QT
The 04/05 Transmission holds .58 US QT

[Colby@C&DRacing]

The 06 no longer has an engine oil cooler

The 06 engine oil capacity .90 US QT
The 04/05 engine oil capacity .82 US QT

Sorry to interrupt the post but by the picture it looks like you could just add a small bracket to bolt the pipe on. Or are there other issues?

[Colby@C&DRacing]

The 06 engine oil site glass is now under the filter where as the 05 is back by the shifter

[Colby@C&DRacing]

The 06 transmisson fill hole is towards the rear of the motor and higher.

[Colby@C&DRacing]

The 06 thumb throttle has changed to accomidate Honda's/ Keihins Lawyers, it is equiped with a throttle override switch similar to the one found on the YFZ450, this will sense when the carburator slide is in the up position but the thumb throttle is released this will cause the atv to not run much over idle, this could be bypassed to use a different throttle.

[Colby@C&DRacing]

We are going to break it in tonight and will have more feedback. I tried to leave it stock but the wife said she had to have the Flexxbars and the autoclutch for right now.

So far the Rekluse is pretty close I had to make some minor adjustments but I will know more after tonight.

[kbass24emtp]

What does the linkage look like?

[culookn]

if and when i ever ride again thats what im getting. espically with the electric start now.

[stryker]

That is what we all wanted to see. Great job Colby!!:D I'm looking forward to the ride review.

[asdf450r]

wow.. all i can say is wow !!! anyone know the weight addition on this bike vs 04/5?

[Pappy]

colby, thanks for the info!

[Kilabanshee]

Colby I talked to you on the phone when I ordered some parts a few days ago. We were talking about the 06 fcr carburators and if they would plug into the 04-05 wiring harness. If you find out a price or any more info please pm me asap.
Thanks,

Brent

[Dave400ex]

It looks awesome. That battery area sure is big there under the fender, kind of looks ugly with all that plastic, but as long as it works...

[JRDrider22]

hows the motor run now with a higher compression?

[quad9]

i rode my buddys 06 a little while ago. i did not crank on it 1st thing it was not mine, and he had only rode it 2 min.
you can tell a BIG difference with the compression, and the fcr carb. the throttle responce is great. the front end has more neg camber the the 04-05. it turns better. i cant say i will sell my 05 and rush right out and get a 06. but there is enough changes that if i were getting a new one and a 05 was sitting next to it for
$800 cheeper, i think i would pay for the 06. we measured the rear end and are pretty sure the axle will interchange, i will give Tim my stocker 05 and see if it will fit the 06. the seat interchanges we did that. the wheel base is the same 05-06 we measued that. i still think i would like to have a oil cooler on it but i'am sure the boys at honda know what they are doing. I hope to get some real seat time on it this week end (after the owner puts the 1st scratch on it). then i can compare the 05-06 a little better. after it has a little time on it, i want to see it run a piped yfz, i think it will give it a good run.
sorry to ramble on.

Thanks for the info on the carb! I've been looking into getting a carb for my race motor for the longest time. The 450r carbs that are already rewired from baldwin and other companys are around 6-700 bucks. Hopefully this carb will be around $400 and will plug right into the 04-05 wiring harness.

[d kelley]

I ride yamahas but that post is friking awesome. I wish more companys would (or could) do this kind of post. Hats off to C&D racing

Hey that have a neutral light now too

[Johnny & Monica]

Great report Colby You coming down to go riding tis weekend?I sure would like to roll that down one of those hills in the rock quarry:devil: Kidding ...Your welcome to come down an go riding this weekend thougth.Sorry an Dusty to.

Great job Colby and Dusty! :macho Excellent pictures and write up. (Personally, I am glad to see you doing this project on a "Honda Red" 450R!:) )

You can get a CRF carb for about $360, a Noss Machine adapter for around $65, and you can rewire the 3 wires in the connector yourself in a matter of about 10 minutes...

[Punk'd]

Man.. your post makes me want a 06 even more.. DANG 04!!!!!

Id like to know how it compares to a yfz and a 04/05 450r.

Thanks for the post, Its awesome!

[450robot]

i really like the 06! man! i didnt think i was ever gonna like that hood and light, but it has really grown on me!

can you give us a report on how and where it shines compared to the old model?

and i wonder what the operating temp difference will be with more power and no oil cooler, i doubt it will be much, but im just curious

[Transplant2]

[Smoker]

I was wondering if you could post a pic of the side case above the starter to see what the major differences are? Thanks

[Colby@C&DRacing]

Well after the first ride, Let me back up first and tell you what our 04 has on it..

04
13:1 Thermal coated JE Piston
HRC Kit
BUB Moto C4 full exhaust
Rekluse
Flexxbars
C&D Racing shock conversion front and rear
IMS Pegs/AC Nerfs
Razr 2 fronts
HD rears
Muscle steering dampner
there is more but these are the important ones...

Now back to the 06. I installed the Flexxbars, Rekluse, HD tires all around. It is amazing how accustom you become to your bike setup. It took a while to get used to riding a non ssd shock set up, Although I did back the preload off the shocks, The 06 suspension feels pretty plush and does a good job cornering for stock ride height. The rear shock is alot more plush doesn't have a harshness in the stroke, and doesn't seem to buck. I did turn the rebound on the rear shock to about 3/4 of a turn out and the compression was 1.5 turns in. The front shocks I left the rebound at the factory setting and the compression at 1 turn in. Today I will be installing a C&D Racing shock conversion for all 3 shocks to lower the center of gravity like I have become accustom to. I hope this will aid in steering and control, the 06 feels a little light in the front end and is a little twitchy and seemed to push in the corners. The pushing in the corners could have been the front tires I am going to try razor 2 on it tonight. We are also use to running a steering dampner so that could have been some of the twitchyness.

As for the motor, The first thing that has got to go is the pipe I hate the sound of the stock pipe :scary: Aside from the lack of noise the 06 pulls good from the bottom to the top, it has plenty of bottom end something the 04/05 was lacking, seems to have a good midrange hit and pulls strong all the way to the top. The gear ratios felt good, Never seems to be too high of rev in one gear and not enough rpm when you shift. I think the FCR is a nice addition to the 06, Dusty did mention that her thumb was a little fatigued from riding the 06, we are not sure if it was the extra pull from the FCR (which I did not feel) or if it was throttle positioning or the thumb throttle itself.

Make sure when you get yours to check the toe in and toe out, ours was way off from the factory.

Hope this gives you some more insite My overall thoughts between the stock06 and the stock 04/05 Suspension has improved, Motor has improved and gearing has improved. The 06 would be a great stock class machine.

Tonight we are going to dragrace the 2 :macho

[Johnny & Monica]

I'm rooting for Dusty in the drag race.:D

Monica

[86atc250r]

Check the throttle adjustment while you're at it. New Hondas are notorious for having the adjuster screw adjusted all the way in from the factory, which many times prevents the carb from fully opening.

Man I thought you would be going to Waterloo. Thanks for the invite but we won't be able to make it down this weekend. I think I would get a beating if the new bike - (Dusty's :uhoh: ) gets rolled :ermm:

[Punk'd]

What is that blocking were the kickstarter goes? Just metal?

And I thought it was still called a 450r?

can you photo where the starter enters the center case?

[duke416ex]

Any word yet on whether you can install a back up kick starter on the e start versions?

[Colby@C&DRacing]

Another interesting find on the 06 stock exhaust is that it is not a chamberized muffler, after removing the sparkarrestor it is a straight through all the way.... We took the HRC end cap off the 04 exhaust and are in the process of rejetting now.

[Jonas]

For what it's worth, it will say trx450er on your title but trx450r on both quads.

[Colby@C&DRacing]

The stock 04 muffler chamberized.

[Colby@C&DRacing]

The rear plastic uses a different fastner on the 06 up by the fuel tank should stay in place a lot better.

[Colby@C&DRacing]

The tank is off

[chad cavagnaro]

colby, do u feel the new carb is harder to pull the thumb thrtl. like the yfz's, or as easy as ur 04/05 model.

[rap169]

will the rev box from the 06 work on the 04/05? I heard that the 06 has a higher rev limiter than on previous models.

[Colby@C&DRacing]

FCR Carb

[Colby@C&DRacing]

The black cover on the carb is hiding the throttle override system.

The stock carb comes with a 42 pilot and 120 main jet.

i believe it is harder. i rode for a hour sunday and my thumb killed me. i am use to 2 hour gncc races. its definitly the carb i had a 39mm FCR on a 400ex years ago and it killed my thumb too.

hey Colby, since the carb is jetted for the extra snorkel in the airbox, would you have to rejet if you added a pipe? thanks

man I can't wait to get my black one:)

After further inspection the snorkle in the airbox lid is not for extra air it is the only source for air.

I removed the lid and uncorked the stock muffler and went to a 45 pilot and 170 main and about 2 1/4 turns out on the fuel screw stock setting on the fuel screw was 1 3/4 we will see how she runs.

Did I mention I can't wait to get an aftermarket exhaust :ermm:

my bad, I thought it had 2 snorkels:o

[TCracin440ex]

i kno this proally sounds like a stupid question.....but does the 06 450r e-start version have trx 450r stickers on the tank or TRX 450ER....ER really dont sound right to me and i was just wondering....id still tell the people its a trx 450r

[Transplant2]

The stickers on the plastic are all the same and have 450R. The model sticker on the frame says TRX450ER.

[onebad450r]

Colby....I was wandering what modifications if any did you have to make to the Rekluse to make it fit the 06?

I have the Rekluse in my 05 and was wandering if I could use it in the 06. I have to wait another week until mine arrives.....Any info would be appreciated

[450robot]

did you notice any difference in operating temp without the oil cooler?

[chad502ex]

Originally posted by Colby@C&DRacing


thank you very much, sir!

[Smoker]

Thanks Colby! I wanted to see how different the cases were to accomodate the starter, it's not just the side case that's different, it's also the one half of the crank case, which is what I thought it would be. No converting the 04-05 to e-start without difficult mods.

[Jonas]

We need some more ride reviews Colby, it's time to take a couple of sick days.:D

[Colby@C&DRacing]

Had a chance to install a spring kit on the 06 the 04 bike sits at 8.5" inches of ground clearance and the 06 has 9" ground clearance now. One mistake I made I didn't measure the ground clearance on the stock 06 :rolleyes: The conversion made a big difference with cornering and high speed stability, more of what we are use to.

We haven't had a chance to do a fair dragrace since it was just the 2 of us looking at each other and waiting for the other to start type situation :chinese: The two bikes seem to be pretty close in power I think the 06 has a little more power but that could also be that our 04 has alot of time on it this summer and is getting week. The 06 does an awesome 2nd gear start but our 04 didn't do so well with a 2nd gear start.

The 06 with the gutted stock muffler, no lid, and rejeted has plenty of power I can come out of a corner in 3rd gear and mash the gas and not have it bog down to where I would normally have to shift.

I haven't noticed a difference in operation temp on the 06.

Dusty still notices the thumb throttle being more fatigueing. I can tell a little difference but it doesn't bother me as much as her.

We are supposed to race a non points harescramble tomorrow but it looks like it is raining their today and 82 percent chance of thunderstorms tomorrow, I really don't want to race in the mud :ermm: but we will see..

[MXRACER86]

Can you put a kick start on the electric start model?

[Jonas]

putting a kick on the electric will not be a Honda accessory and is not recommended by Honda. Whether it is possible is another story.

[370kingR]

That was an awsome review Colby. Great job, we all appreciate it.

[jamiesel]

Can you tell me that the first digit in the VIN is? I would like to know if this first batch is the american made ones or the Japaneese imports. Thanks.. and are you atemping to cut the throttle spring? Please advise us with pics if you do, I hated my YFZ throttle and don't look forward to two more years of thumb suffering!

[86atc250r]

The YFZ's throttle problems are not due to the FCR, they are due to a poorly designed throttle assembly, switching the YFZ to a Honda throttle assembly cures it's problems.

I run FCRs on all my quads. I've raced countless 2hr harescrambles, and even the 2003 12hrs of America race and have no problems with thumb fatigue --- a 10 minute TT race on a YFZ will have me throtting with my palm or doing the "finger wrap" around the bars.

Another thing I've found is that the adjustment of your thumb throttle has a lot to do with thumb fatigue. Actually rolling the throttle up somewhat will substantially decrease your liklihood of experiencing fatigue.

[400exc]

so is the 06 fuel injected? just wondering, you should clock it out too colby to see what the top speed is for the 06 compared to the 04/05

does it do nice wheelies also, better than the 04/05 models?
how was the drag race also?

[450 Racer R]

it has an fcr carb. it's not fuel injected.

[desratt]

is the ignition the same as an 04/05 or is it a crf rewound for lights and fan?


will a 04/05 swingarm linkage and shock bolt up?

[Punk'd]

I linkage has changed and correct me if im wrong, but a 06 linkage and a 04/05 will not work.

[desratt]

I'm not saying put an 06 linkage on an 04

i'm saying put an 04 swingarm linkage and shock all as one package on a 06.

so if none of the 3 mounting points on the frame(upper shock mount, swingarm mount and linkage mount) have changed it should work
I haven't read anything about them changing

[BSTURDIVANT]

Swingarm mountand shock mounts seeem to be the same.

It looks as though Honda wanted a YFZ style MX machine by removing the oil cooler, thinner radiator,smaller fan,etc. on the 06'.
They should have taken proven parts and replaced ones that were mis-engineered!!!

The 06' has a completely redesigned CRF450X style engine with smaller engine cases, shorter cylinder,head designed with smaller ex. port outlet, short stroke.

Now we have to test it again for them instead of changing a junk frame design,junk crankshaft,etc. Who knows what problems will arise from titanium valves, no oil cooler, small fan, TOS, and a starter that will barely turn the engine!!! Some said that the electric start version was for cross country and trail riding-not from what I've seen!!!

[86atc250r]

Wow, those are some pretty negative comments.

Personally, I think the 04/05 was a very good base for a race machine & the race results out there prove it -- it had one trouble spot on the frame which is A LOT better than I can say for the bulk of the other ATV chassis's out there. There were sporatic crank bearing problems, certainly not enough to call the crank junk - if the crank were junk I'd sure think that some of us out here with very heavily modified engines would be having substantial problems, and we're not.

The 06 looks like a lot of nice refinements to me. Really, in my opinion the only thing that really needed to be addressed was the rear suspension setup -- looks like they did a little, at this point it's difficult to say if they did enough to make an appreciable difference or not.

They made a lot of nice changes to the the engine that will prevent the bulk of users from having to make the number of changes that many of the 04/05 users have made - for the most part, an exhaust and a cam should be all you need to make an 06 a very powerful machine.

It's a good time to be racing ATVs - with the 06 450R and the 06 YFZ's racers have the choice between two very powerful weapons that were practically unthinkable only 5 years ago.

I agree! the 06 450r is more than what I thought Honda would come up with and I think if you put a exhaust and open up the air flow a little your going to have a awsome quad.:macho

i almost forgot the YZF is the greatest thing since sliced bread. :rolleyes:

[coryatver]

i almost forgot the YZF is the greatest thing since sliced bread.

I am pretty sure he races a 450R!

[BSTURDIVANT]

Not trying to be negative about the 450R because we race it and wouldn't use anything else for XC unless the new Suzuki works! It's just that Honda engineers are more concerned about the bottom line lately and yes, like Yamaha, tend to cater to MX. The 06' may prove me wrong, but the changes leave me guessing about the reliability of 2 hr long XC races without some reverse engineering (old fan and radiator,etc.)

The older models are really reliable but could use a stronger rod and bearing and a stronger frame. I know of 4 crankshafts with rod failures with less than a season on them. We have replaced 2 frames this season and 1 we run is welded at the front shock mounts, steering stem riser,upper frame tubes both sides, right forging behind kick starter, and the foot peg area. Reinforcing the frame area next to the upper engine mounts is only causes it to break where it's harder to weld! Best thing is to run untill it breaks, weld it and run untill not worth welding anymore!

Honda engineers are aware of the problems and could have designed an electric start around the current engine design.
This would save racers money by being able to use current piston
and exhaust designs!

Looks like we'll be running the 05' models again next year! They are a proven winner!!

[Dave400ex]

It seems anything raced hard, will have frame problems sooner or later, all though I do agree, Honda knew of the problems, so could have fixed them. I think the changes they did make are very nice, and will be a big difference, and should be good for all types of riding. I guess only time will tell how good it is, and how reliable it is...

[RedRacer44]

My local Honda shop owner went to the Honda dealer show and was told by Honda that the frame issues were addressed as far as the upper frame rails where everyone (including myself) were breaking frames.....

No matter how good you make a frame....with the right amount of punishment, they're going to break....

I've seen aftermarket frames break too.....nothing is perfect :rolleyes:

Well we put our 400ex's throttle on our yfz and it was only a little better. When we rotated the spring (didn't cut ours) it was way better.

My son races XC and was having heck a heck of a time with his thumb. Now he doesn't even mention it.

I played with the throttle on an 06 R last weekend and and it felt stiff to me.... But everyone will get a chance to see what they think soon enough.

By the way this is not meant as some lame attempt to put down the R, I plan to get an e start R as soon as i can figure out how to pay for it. Not getting rid of the yfz though, heck I still have a 426ex that could still win races if need be.

[Silverfox@C&DRacing]

I had a chance to race the 06TRX450ER but first I have to thank Colby for spending 3 1/2 days working on this 06 to make it feel somewhat like the 04 that I am use to. We raced a non points harescramble in Waterloo IA on 9-25. We left early in the morning for our 4 hr trip, with rain pretty much all the way there and still raining when we arrived at the track.
I really did not want to continue the breakin on the 06 in these conditions, but I bit the bullet and decided to race the B class. The start was rather interesting standing on the left hand side of the atv facing the rear of the atv with the left hand on the handlebars and right hand on your helmet. I left the 450r in gear with my thumb on the push button starter (good thing Colby had the 04 kickstart);) I must say he had a decent start against the rest of the electric start atv's, as for mine it started when the button was pushed and away I went I am not 100% sure where I was off the start, midpack or better.

I was still trying to get a feel for the 06 as I did not have a chance to ride it after a steering stabilizer was installed, handguards, new fabricated footpegs, and steering stem stops ground down for sharper cornering.

The 06 felt pretty good underneath me the mud was so thick but yet slippery. The track had quiet a few long straight aways that were extremely muddy the 06 had plenty of power in these situations clicked third gear and rolled into the throttle and hold on. About half way through the firts lap I had to take off my goggles because the rolloffs would not work so I slung them over my left wrist and kept going, (this was the 1st time riding with out goggles and I must say I DO NOT recommend this)

A little while after this I noticed that my thumb was getting fatigued from the thumbthrottle and the FCR carb. I tried to rotate the throttle up as much as I could, this helped some but I need to move it up more and was not able to needless to say my thumb is killing me today.

The track had a few whoop sections, The 06 did a much better job through these than the 04 I noticed through these sections or through breaking bumbs I would have to be off the seat on the 04, seems on the 06 I can be a little more lazy if I had to be.

The track also had a few mx jumps singles and some tabletops, I did not hesitate to hit these the 06 felt good hit the jump land mash the throttle and go. Some of the tabletops were a little scary as they were narrow with deep mud on the sides that try to suck you in. I had a few close calls with this and about went down the side :scary:

I was coming around the 1st corner to scoring on the 1st lap chucked my goggles, pulled up to scoring and the 06 decided to die. I push the start button it cranks and cranks won't fire so I get pushed off the side crank crank still no fire the track workers were trying to help asked where the choke was, it was fine , I made sure the tether was hooked up still. I run a shorty vent hose off the gas cap it was covered in mud I wiped some of it off played with it for a second and the bike fired.

I went for lap 2 still feeling really comfortable amazed with the power and gearing can't wait to hit the straight aways and the jumps powering up the hills with the Rekluse having a pretty good time getting to know the bike, and then I went off a down hill there were 2 logs across the top of the hill and the front end went down first and the rear bucked on the logs which made my left foot come off the peg and get underneath the bike (I am currently not running nerfs) and the bike died again so after I got my wits about me I crank a few times thinking now what is the problem well I must have somehow hit the tether and it was out dangling, pluged it back in and finished that lap came into scoring to only have it die again. I cranked and cranked took the gas cap off and the bike fired, put the cap on and went for lap 3 (if I would have been thinking I would have pulled the vent tube off)

On lap three I am trying to make sure that it doesn't die again I went to push on the killswitch to make sure it is good and tight and I get shocked (First time for everything) I kept going still kind of having fun REALLY likeing the feel of the 06 other than the dieing and sputtering problem. Come to an uphill and get half way up it and it died again I rolled back down took the gas cap loose and it started came around to scoring again and yep died again.

I ended up completing 4 laps and finishing 10th in the B class out of 13 people not pleased with my finish. I am glad I did have a chance to race it before our final points race in the Iowa harescramble series. We now know what needs changed (vent tube and Killswitch).

I wanted to tell you all about the first race with the 06 and be honest, but don't let my problems with the 06 reflect poorly on the atv it was 2 aftermarket parts that I installed that caused me problems in this muddy terrain, I feel if the track conditions would have been lets say not so sloppy and muddy the 06 would have shown what it really is. Of course the caliber of rider makes a difference ;)

[Silverfox@C&DRacing]

This is after the race and after I took it too the river to wash some of the mud off :cuss:

[Silverfox@C&DRacing]

More mud :scary:

[Silverfox@C&DRacing]

I also got rearended on the 1st lap thank goodness it only dented the hrc endcap :)

[Silverfox@C&DRacing]

Colby fabricated me some footpegs for the 06 since I am use to running the IMS pegs with the kick up. I couldn't get enough leverage with the stock pegs so he took the stock pegs off the 04 cut them down and used them for the kickups and took the 400ex pegs cut them down and used them to add more width.

[Silverfox@C&DRacing]

Another thing I had to deal with is the handguard covering the clutch lever scared the bejesus out of me the 1st time I grabed for the clutch lever and it wasn't there. I am so glad I had the Rekluse installed because I fought the handgard for 1.5 hrs and didn't have to rely on the clutch lever.

This is the 1st time running the Powermadd handguards, we thought they were tight but must have needed more.

[Silverfox@C&DRacing]

I am really pleased with the 06 electric start and would NOT trade for a kickstart model. I can't wait untill my thumb is unsore and can ride it again (couple of days :D ) Now its time for the cleanup :ermm:

[tido450]

the sore thumbness has to be from the fcr it was so bad on my yfz i made myself get used to a twist throttle. guess now we arent gonna be the only thumb whiners lol. and by the way awesome write up

[Dirtiredneck]

Awesome write up. I just ran my friends 05 450r on Saturday at Unidella and loved it. The only thing I did not like was the kick start. I have raced 4 times this year and every start I have made it out of the whole in the top 10 except for this weekend. I stalled it at the line :). Anyways, the power was awesome, but stalling and kicking back over was a pain. I still ended up 11th I am getting a 450 next year and your article is going to make or break me from getting brand new or a hooked up 05. Keep up the reviews....

Thanks

[RedRacer44]

The IMS-Roll foot pegs for the '04 and '05 do fit on the '06s right?? Just hate to loose my foot pegs cuz I love them sooo very much!!!

[Colby@C&DRacing]

they do but I didn't have any here at the time

[RedRacer44]

Alright thanks colby! How did the rear end work out on the conversion??? I have a conversion similiar to what you guys do and with the GT Thunder MX linkage, I was talking with my local shock tech and he thinks we can re-use all my parts off my rear shock except for the main spring....that we'll have to use a 9-inch rear main spring instead of the 8-inch I'm running now. Did guy guys run into this?

Also, I'm pretty sure I cant but just wondering if ya think the GT link will work or actually be worth using on the new rear end?? We're guessing right now that we'll have to change the rear main spring and change the valving.....use the stock linkage and it should work pretty well.

Also, have you guys thought about re-locating the battery or anything?? We were talking about maybe trying to relocate the battery possibly where the oil cooler used to be on the '04s and '05s....your thoughts on this since you've got a bike to look at 1st hand would be appreciated!

I didn't have a chance to revalve the stock suspension, I just installed a spring kit front and rear to lower the center of gravity. I used a rear 7" main spring and crossover and ssd spring. The stock spring is 10" to run a dual rate rear set up the main spring should be around 7 inches. as for the GT thunder linkage you would have to measure it but I don't think it will be long enough. I have no plans on relocating the battery as of now.

The 1st digit in the vin # is J as for the throttle I think I am going to try and remove the throttle return spring in the throttle. I wouldn't do this on an atv that didn't have a throttle overide system ;)

I have the Rekluse in my 05 and was wandering if I could use it in the 06. I have to wait another week until mine arrives.....Any info would be appreciated

The rekluse installs the same as the 04/05 right now we are trying a different throwout spacer but I am going to go back to the one that fits in the atv.

[Colby@C&DRacing]

The 04/05 alternator is 214 watts at 5,000 RPM's
The 06 alternator is 200 watts at 5,000 RPM's


The 06 has a 12v 6hr battery
The battery is a YTZ7S

The 06 ignition firemark is 11.4 degrees btdc at idle
The 04/05 ignition fire is 12 degrees btdc at idle

The 06 CDI box has 3 plugs. The 3rd plug controlls the throttle switch, the HPC, battery, and carb switch.

I haven't riddend it that way but unpluged it and started the atv and let it run for a while rev it up and ran like it did before.

Due to the different Caster angle, will aftermarket 04 A-arms fit on a 06 bike/spindels?

[TBD]

If this has already been posted I applogize but the arms are slightlly different. The change to the spindle was that they added more pin inclanation so the upper arm is 8mm shorter.

[fastrider450r]

wow this is the greatest and most knowledgeable thread i've ever read on this or any site. great work Colby and Dusty. Good luck with the 04 and 06 in the Iowa H.S. series...i believe this thread should be a sticky

[beerock]

06 gear ratios
primary reduction 2.739
final reduction 2.923

1st gear 2.230
2nd gear 1.785
3rd gear 1.437
4th gear 1.181
5th gear 0.962

04/05 gear ratios
Primary reduction 2.739
Final reduction 2.714

1st gear 2.071
2nd gear 1.625
3rd gear 1.333
4th gear 1.120
5th gear .963

from the gear ratios it looks like the 04/05 450 would be better for high speed with work done to the motor then the 06 would be
from 1st to 4th.

It also looks like when you shift into 5th on the 06 you will be lower int he rpm's then the 05. kind oflike shifting into 5th on a 1986 honda 250r tranny. compared to a 1987-89 tranny

the motor definately feels stronger on the 06 because of the ratios.

One thing that wasnt mentioned was first gear crawling speed, how is it, from the ratios it seems it is definately improved.

I thnk a 04/05 stock for 06 stock drag race is in order.

04/05 Camber angle 0 degrees
06 Camber angle -1.9 degrees

It seems the 06 can take turns at higher speeds due to the camber. Is the camber built into the spindles or arms? if so sounds like a hot setup would be to switch on a 04/05 to a 06, if its possible.

04/05 Caster angle 5.87 degrees
06 Caster angle 5 degrees

seems like the caster on the 04/05 would be more suitable for higher speeds in a straight line.

[Nick110]

will the 04/05 nerfbars fit on the 06. im assuming that they will just want to double check. im gettin xfactor propegs.

ok so isnt the hrc cam the crf cam from the bike? isnt that the same cam the new 06 comes with? if this is true then the 06 has mroe grunt for MX but the 04/05 will be better for high speed riding, like dragging and baja style.

Can you let me know where you found your information. If you go here:

http://www.********.com/machines/honda/hondaridetest450-06.htm

Click on the HRC video and they explain the the HRC cam for the 06 450R is the CRF cam.

[Airik79mx]

The 06 HRC cam is a 06 CRF cam.

[RedRacer44]

The '06 HRC Cam is the CRF cam, after inspection the heads are almost identical between the '06 TRX and the CRF bike head so naturally why wouldnt Honda use it?

The aftermarket has been selling it as a drop-in cam to consumers too so its a relatively smart decision on part of Honda....

The OLDER HRC Cams were different than the CRF cam though, for the '04s and '05s....as far as I know.

Thanks for the info. So since you have taken an 06 450R motor apart can you let us know on the similarities and differences that you see between the CRF and 06 TRX.

Thanks

[RedRacer44]

I personally couldnt tell ya EXACT differences but I was present when a friend of mine was tearing his apart to build and he was measuring different things. He just pointed things out to me that were in likeness to the CRF. Valves, valve guides, head design, etc etc....were in likeness to the CRF, stuff we all know now. I'm not an engine tech and dont even wanna get my tit caught in a ringer when I'm wrong.....

Cuz we all know how some of the "engine gurus" on this site like to bust peoples balls :rolleyes:

Did you try the full system or just a slip on?
I was told that a full system from the 04/05 will fit the 06's.
The only thing that's changed was the silencer.
Does this make sense?
by the way, JPMX gave me this information.

Did you try the full system or just a slip on?

I tried 2 full systems the head pipes are bent different from the 04/05 to the 06

I could have mounted the silencer no problem but it would not have fit the headpipe

I bet he doesn't know this (head pipes having different bends).
When are these pipes ready for purchase?
How many jets do you get with the hrc carb kit?
Where would be a good starting point on jetting with a full system? I live in Ky.
thanks again Colby
