450r swingarm cleared up!

[mmbintn]

It fits with no problems. I just put an 08 swingarm on mine and I used all the EX parts on it. The only thing it needs is a longer chain but its a longer arm so that is to be expected.

So just so there are no questions....All parts fit from a 400ex but the chain.

I just wanted to post this because I read hundreds of posts saying that you will need a whole rearend from a 450r or this or that from the 450r. Hopefully if someone does a search they will see this first and skip the others.

If anyone has any questions I will be more than happy to answer them.

[honda400ex2003]

sounds cool thanks for the info. steve

Another

[matt14c]

So now thats a 450r swinger with 400ex brake stay, carrier, caliper, link, shock, spacers for the pivot bolt next to motor, lock nut, axle and rotor hub.

Yup everything and the brake line, although not OEM, is stock length. As soon as the new chain gets here it will be back together.

[matt14c]

Are all years 450r swingers the same?

[mmbintn]

No the 2006 and newer are longer. I think the 2005 and older are the same length as the 400ex

[tri5ron]

Interesting,
did you by chance take a picture of them laying side by side ?
and can you tell us how much longer the 450r swinger is than the 400ex swinger?

[mmbintn]

I did not take pics of them laying together as there are already pics of that here but I took multiple measurements and it it just about 1.5 inches longer than stock.

[tri5ron]

Next question,
do you know if a aftermarket skidplate for the 400ex swinger, will fit on the 450r swinger??? That would sure be nice if it does.

[mmbintn]

I have an aftermarket skid and I will make it fit. I think its an AC Skid but will have to look. On another thread the guy said he made a 450r skid fit his 400ex with a little grinding on the bolt holes. So it should not be to hard.

[tri5ron]

It's starting to sound better and better already !!!

now next question...
Do we know , FOR SURE, that the '06 and newer 450r swingers, are longer than '05 and older?

is there a way to lookup the part numbers from both years to compare ???

[mmbintn]

Give me a few and I will have the part numbers.

[mmbintn]

04/05 part number is 52200-HP1-000
06/07 part number is 52200-HP1-600
08/09 part number is 52200-HP1-A00

[tri5ron]

"I see", said the blind man...

So now the plot thickens, with 3 different numbers.

[mmbintn]

Updated part numbers

[mmbintn]

In 2006 the 450r got and inch longer. it went from 49.2 to 50.2 inches. While the 2008 400ex is 47.9 inches.

[bergoff]

awesome to know. i have a friend that races a 06 450r and asked me if i needed any parts. i will be buying all of the suspension i guess. and the nice thing is that the shocks have already been worked for my weight.

[wrekd]

So 06+ swingarms are 1.5" longer and will bolt up to any year 400EX??

[mmbintn]

Yes they are around 1.5" longer and will fit any 400ex

[riotact]

Looks like the 06 is the way to go then.Thanks for the info.It will be great to get an extra 1.5" for about $100 compaired to 300 or 400

[johnnynonails]

with you having a 07 ex,just wondering for us with older ex's, are the rear caliper mounts the same on newer ex's as older ones ?.and how many extra links would the chain need,thanks john (uk)

I went and bought a new chain as I needed on anyway and the old one was to short. The 450r calls for a 520/96 tooth chain but I went ahead and bought a 100 link just to be safe (it was only 2 bucks more). I will just cut out the extra links.

The part numbers for the brake stay are diferent and without looking at an older model EX I couldnt tell you 100% that it iwll fit.

[fatboy250]

Was there any changes in ride height? If so how much?

Thanks

[Miami_Vice454]

did you change just the swingarm or the shock too

[mmbintn]

Just the swingarm, slider and chain.

[Miami_Vice454]

ok this is awesome im gonna do it

[johnnynonails]

just for the older ex owners,ive just put the 450r swinger 06 model,on my 2001 ex i bought the swinger and linkage.already had the 450r rear shockers fitted.swinger went in a treat,axle carrier,rear brake stay and caliper also.i tried the 450r linkage,but it lowered the ride height by 40mm,so i put the old ex linkage on.the chain slider dont fit,and as i run a 16/36 sprocket set up the chain goes on but is tight,im going to put a 35 on the rear anyway so i'll see how it is then.and the ex looks better being that bit longer to.i dont use a swing arm skidplate so i dont know if it fits.hope this helps the owners of older ex's.john (uk)

[coryatver]

the suspension travel and linkage ratio is not going to be correct if you put the 450r swinger on the 400ex.

I'd like to see the two swing arms side by side, any any other pics would be helpful too.
before and after ride heights, wheel base length, etc.
also, let us know if you need to increase the spring preload on the 400ex rear shock, once it is being used with the longer 450r swingarm.
Thanks for the info., and if you've got pics, please post them up.

sorry no pics,just went and did it,ive got a 450r rear shock not the stock ex one

Good info...Thanks

[-TheDude-]

if i put a 450r swingarm on my 400ex. this winter when i get my 400ex rear shock rebuilt and buy a new link. should i buy the gt thunder xc link for the 450r or 400ex??????

[tri5ron]

after talking to my local Honda dealership, I have determined there are 3 different part numbers on various years of 450r swingarms. Unfortunately the parts departments do not have a way to determine the dimensions.

I have found a article on the '06 450r, that states the swing arm was lengthend 15mm to prevent "bucking" that the '05's suffered from.

the '05's and earlier have one part number.

the '06 and '07 have a different part number (same number for both '06 and '07).

the '08 and later have a (third) different part number.

I have not been able to find anything describing or saying that the '08 swingarm was changed from '07, but it does have a different part number from the '07's, so I dont know what that difference is on the '08's.

maybe you guys that have done this mod, or also own a 450r, could chime in here, and give us the year, and also measure the distance from the center of your piviot bolt, to the center of your rear axle.

I realize that this measurement might vary a little bit, due to chain adjustments. but it would be nice to have an idea of the actual differences in length on these 3 different part numbers for the 450r swingarms.

it is easy to use a tape measure on the left side of the quad, and measure from the center of the pivot bolt, to the center of the rear axle.

so help us out here guys, and list those years and measurements of your 450r swingarms.

Thanks

i would buy the one for a 400 and have your shock valved for a +1 swingarm. that would keep the rear end 400ex geometry.

[Rich250RRacer]

How is the 400EX carrier used in the 450R swinger? The carrier in a 400EX is longer than a 450R carrier, which means it will stick out of the swinger too far on the brake side.

[monster400ex]

the rear caliper bracket looks very different from the one thats on my 99
im very interested in this swap my swing arm is cracked i already have the 450r brake and shock

[siggy konowaluk]

that looks sweet. i personally like the 400 swing arms becaure of there shortness. and there good for wheelies.

[childert79]

OK. So I have a 400ex and all i have to buy to get the 06 450r swinger to work is the swingarm and a new chain. Every thing else swaps right over? What link chain would I need to run with 14/38 setup?

[siggy konowaluk]

yeah. he said on the first page that EVERYTHING from the stock 400ex fits onto the 450r swinger EXCEPT the chain.

[childert79]

Just wanted to make sure. Pretty sure the 07 down are the same as far as the swinger and stuff. They just changed up the fenders. The 08 up might be different though.

[honda400ex2003]

the brake stay is also different on the new 400. steve

[johnnynonails]

hi all,as ive just done this mod as stated a few pages back,i have a 2001ex list of things that did and did not fit,

thinks that did fit.

bearing carrier,yes it is longer than the 450 one but only by an 1/8 of an inch,mine stuck out the sprocket side,no dramas.

brake caliper and stay also went right back on.

i have a braided brake line which is slightly longer than stock,but theres loads of brake line left.

the swingarm bearing kit works.

i put the 450 shock linkage on,but it lowered it to much for me,i left the 450 link from frame to2nd link,then put the 400ex link on from swinger to shock.

things that didnt fit

chain was to short.

chain slider is diffrent.

not sure about the skid plate as i dont run one

[TRX01]

ok thanks johnny, for clearing that up for the guys(me) with older models

[honda01400ex]

i want to do this mod can you post pics of your bike with the 450r swinger

just put a few in show ur ex,they aint the best as it was dam cold today,i'll get a few more when its not so windy and cold.john

hey johnny, i was wondering if u could get a pic of ur bike right behind ur swinger, like and up close pic of ur swinger from the back....i want to seee what it looks like and how far it sticks out i no u said the carrier sticks out about 1/8 of and inch, but i wanna see a pic

thats why we are all here to help each other out.:) .glad i could help you out,like others have helped.

[quad2xtreme]

Reason I would like to do this...

450r brakes are better and easier to change

brake rotor on 450r is smaller thus it isn't as low to the ground

Lonestar makes a great stainless brake rotor guard for the 450r swinger that isn't available for 400ex swinger.

Lonestar makes a great stainless sprocket protector.

You can grind the two small tabs off the brake caliper holder which allows the chain to be tightened with the carrier more towards the ground thus raising the swingarm up by 1/2"...give more ground clearance. This usually requires taking a link out from the stock chain.

This results in better protection, better braking, and more ground clearance.

[2007TRX400EX]

Would it be worth it to buy a 2004-2005 swing arm?

[quad2xtreme]

That is what I bought.

[johnnynonails]

as stated earlier,04-05 450 swingers are not any longer than your stock ex swinger,( if i read it right)

[2007TRX400EX]

I thought i read that to but then someone said the 04-05 was 49.2 and the 06-.... was 50.2, so i dont know.

[johnnynonails]

just had a very rough measure of the 2 swingarms,was a bit hard to get an exact measure on the swinger on the bike ,but i will get that tomoz.

stock 01 ex swinger from the outside of the front swing arm bearing end,to the rear tip of the 4 bolts that tighten the carrier in are 21-1/2inches

06 450r swinger measured from the same place is roughly 22-1/2 inches.

i'll get a bang an measure tomoz,coz ive only a small shed to store my quad in.

[400exrider707]

Last I knew, 06+ swinger was .85" longer than the 04/05 swinger (talking about 450R's)

I dont see this working well. I can see you have it mounted and what not, but something is going to be wearing out fast. The 450R carrier is shorter in overall length, meaning your 400ex carrier in the 450R swinger is going to be sticking out on one side or the other (which also means it can move around, side to side), so everything will be shifting no? Your chain will now have side to side play on your sprocket, or your brake rotor will now be pressing side to side on the pads.

Also the 450R rear shock is actually shorter and sprung quite differently than the 400ex rear shock. Mounting a 450R rear on to the 400ex rear will result in a lower stance yes, but a screwy progression, and possibly allowing it to travel too low (maybe making contact between the frame and ground!?)

I still say this is a bad idea. If you want to do this, use the 450R carrier and axle too. JMO.

For me, this was a good thing. I want to keep it as nimble and tight turning as possible in the woods as well as being able to bring that front end up.

[quad2xtreme]

looking back through magazine articles when the 2006 was first released, it says the 2006 swingarm is 15mm longer which is about 1/2".

there is no side to side movement on the rear at all,the brake rotor spins freely,and there is no side to side play on the chain,we are talking an 1/8 of a inch longer for the ex carrier not a massive amount.i personally had a 450r rear shock on my ex swinger before the swap,and i thought it was a better shock than the old ex one(maybe it was knackered).the 450r shock has never bottomed out on me in mx races.
sorry if anyone was waiting on the sizes for the swinger,but i got in late from work,will try tomoz.john

[quad2xtreme]

Did a little measuring tonight.

A 2006 450r swingarm increases the distance between the swingarm bolt and the axle by one inch over the early years' 400ex swingarm.

I am betting that the 2005 swingarm will increase the distance by 1/2" as the 2006 swingarm is 1/2" longer than the 2005 450r swingarm. I have a new 2005 swingarm showing up in a couple days so I can measure and know for sure.

The width of the rear portion of the 400ex swingarm is wider thus the reason the carrier is wider too...no surprise there.

I haven't measured so I am guessing that if you run a 400ex axle then you probably need the 400ex carrier. I am betting the groove for the c-clip is located a little further out on the 400ex axle than the 450r axle. If you tried a 450r carrier with a 400ex axle, you would probably run out of threads on the bell nut before the axle is tight. Just a guess at this point...

[quad2xtreme]

johnnynonails,

Why did you leave the excess space on the carrier sticking out on the sprocket side? Was this required to have the rear sprocket in alignment with the engine drive sprocket?

Or, did you split the spacing difference and put a little on each side?

Thanks,

Jon

[buster024]

The carrier issue concerns me as well. I shredded several sprockets after I installed my aftermarket swingarm from SLC Quad Customs, until I figured out I was missing a small spacer that re-aligned the carrier correctly. If you are off by anything at all, I'm betting your chain is going to wear deep grooves in your sprocket after 1 ride, and will have the teeth chewed off completely after 2 or 3.

[mmbintn]

I've been running mine "evenly spaced" for a good bit now. Even with a 3 day trip to the dunes and have had no issues. I did take it off recently though as I am going with a 6" extended swinger, so it will be for sale soon.

[monster400ex]

just bought a 08 450r swing arm ill left you guys know how it goes

[sameltoe]

Funny thing about the 450 swing arms...there all the same physical length, but were the link mounts up-is different. I have an 05 450 and replaced it with an 06-up swinger and both links. It's all in the geometry of the links...And it only add'd 3/4 of an inch.

That 1/8 of an inch has to go somewhere.

Saying your shock never bottomed out, is not a good thing, you know this right? Your shock/s, when built correctly, should bottom out every once in a while, otherwise you're not utilizing the full travel of the shock in question, it's a waste. Now I'm not saying the 450R doesn't ride better than the 400ex (stock for stock rear shocks), but I am saying, it's not the properly designed shock for it. I've never tried it, and dont plan on it.

This will all depend on where your carrier is located too. Notice it's an eccentric design, meaning it's not centered. If one guy has a chain that is very loose, and has his carrier favored towards the back, he'd have different readings.


15mm = .59"


Dont forget, not everyone will benefit from a longer swinger either. TT guys may opt for a shorter swinger.

I say if you're going to do this mod, use all of the 450R components and do it right.

Just my thoughts on it. Not trying to step on anyone's toes.

My post says 15mm longer which is about 1/2". Isn't "about 1/2" and ".59" the same? I would assume "about" would account for 9/100ths of an inch.

I would normally use the ~ symbol but half the people on this site can't spell so I was pretty sure they wouldn't figure out that "~" meant approximately. :eek2:

[quad2xtreme]

A 2005 and 2006 450r swingarm are not the same length from the center of swingarm bolt to the far edge where the carrier slides in.

I can post the pics this weekend with a ruler on each to show the difference.

I also plan to determine if the smaller width of the 450r is centered or not. If so, this means that it is 1/8" narrower on the left and 1/8" narrower on the right (for a combined difference of 1/4"). This could cause a problem with chain alignment if you used the 450r carrier. At least with the 400ex carrier, you can let it stick 1/8"on the left to keep the chain alignment as engineered.

[quad2xtreme]

The 1/4" smaller width at the rear the 450r swingarm is not centered so 1/8" is on each side. The entire loss of the 1/4" is actually totally on the sprocket side. This is a good thing because if you use a 450r carrier, it is actually wider on this side thus it will make it align perfectly. Honda did this so they could fit 2 bearings in there.

[quad2xtreme]

by the way, the front chain guide on a 450r swingarm is more towards the center than the 400ex one. Thus, the chain rides a bit to the left of the chain guide.

You can modify the 450r one to move 1/4" to the left. There is a tab at the front of the swingarm that fits into a hole in the front chain guide. Fill that hole with epoxy plastic and then use a dremel to relocate the hole. Use spacers and longer bolts to mount the rear portion to the swingarm.

The TM Designworks chain guide is a bit wider so it will provide more protection or soon, I expect Glann Innovations to have a custom one for this conversion.

sorry guys,been a little busy to do any measuring ect.i left the carrier sticking out the sprocket side,as the carrier would only go in that far and also the brake rotor lined up spot on.i have temp put my 400ex chain slider on the swinger(tie wrapped it on), and ran the engine threw gears many times to check if there will be any wear.i know it does not simulate race conditions,but ive come across no probs up to now.the carrier has not moved or come loose,the rotor spins freely,and the chain and sprockets are in the new condition they were.
as for my statement about bottominng out,what i meant was yes if you jump big or whatever then yes it will bottom out,but with me just trying this out for the 1st time i didnt wont to go mad with it just incase,i find the ride is plush,with the 06 swinger,06 450 rear shock and half of the 450 linkage.if there is a down side i will post up so you guys know about it.john

other tidbits...

1) the stock 450r brake line makes it a cleaner swap.

2) Although you might be able to use a 450r axle, you definitely need the 400ex sprocket holder. The 400ex sprocket holder positions the rear sprocket to the left by 1/4" versus the 450r sprocket holder. This is required to keep the rear sprocket in alignment with the front sprocket.

something i forgot,i had to make 2 spacers to go behind the 450r chain slider to keep the it inline with the chain.john

Yea, I did the same for now. I actually filled the front hole in when the tab from the swinger fits in and then drilled out a a new one.

I am working with John Glann from Glann Inovations on making his front chain guide fit this conversion. His covers to much more than stock or a TM Design one. In fact, he had to cut a slot just for the subframe mount bolt to clear.

He has good stuff for sure! Great guy to talk to. I have the front and rear Sliders on mine, for a season now with hardly any wear.

[johnnynonails]

the only down side i see,for ppl who run a smaller front sprocket,say a 14t,is its going to have to pull down on the top of the slider to get round the sprocket, i run a 16t front and it works great.john

Looking at doing this. I have the 01 model so an 06-08 450r swing arm shouldn't be too hard to come by. AFter that itsj ust swapping everything from the 400 over to the new swing arm.

I know I'll need the new chain guide for the 450r but other than that FROM WHAT I READ in this thread I'll be good to go. I just have the stock gearing whatever that might be. Then it's just a matter of finding a rear shock for a 400ex with a 2" extended swing arm if my assumption from this thread is correct.

Please someone correct me if I'm wrong.

[johnnynonails]

if u have stock gearin for a 01 it will be 15/38,the gain in lenght is approx 1 inch not 2 inch,ive put a 450r shock on and it works good for mx.
depending on how your swinger bolt comes out.u'll need.......
bolt,bearings,400ex spacers(should be in with bearings),new chain,new chain slider,i think you can mod the stock skid plate for swinger if you use one,(i dont).
easy enuff swop,with the odd mod on the way to make it all fit nice.john

Johnny -
Did you try and run this with your 400ex shock and a 450r shock? I'm just wondering how they compare. I think I might be able to snag an 07 swingarm and have the option of buying the rear shock with it, so I'm not sure what to buy.

I would go with a 450r carrier over stock 400ex...3 bearings instead of 2. Or course, aftermarket would be nicer.

You can modify the front chain guide. You just need to space it 1/4" to the left...a few spacers and longer bolts.

I would guess you could modify skidplate. I purposely did this mod so I could run Lonestar rotor guard and rock ring sprocket guard. I switched over to 450r caliper and rotor too since it provides more ground clearance.

So does grinding the two small tabs off the brake caliper holder then spinning the carrier forward to tighten the chain instead of pulling towards you, It puts the axle on the downside thus raising up the bottom of the carrier...of course this will raise you ride height a bit too...you gain about 1/2" of clearance.

hi,no i didnt,i had the 450r rear shock on my standard 400ex swinger,long before i got the 450r swinger,it works for me,i just inter changed the linkage to keep the ride height.john

Whats the length of the stock 400ex swingarm on a 2001 model? I tried looking it up but couldn't find it. I thought it was around 47" and the 2008 450r was about 50"

behave 47" lol

So far I have a 400ex lsr axle carrier/ lsr axle/ 06 450r rear shock and linkage. I'm wanting to use the 450r rear caliper/rotor setup and 450r swinger. What would I need to get the rear 450r rear brake setup to work? Will all year 450r brakes fit or just 06+? Will an 09 trx450r swinger work? I appreciate all the help.

[quad2xtreme]

2006-2009 swingers are the same.

Brake calipers, brake stays, and brake rotors are the same from 2004 on. You will need the brake rotor holder and the brake caliper stay from a 450r too.

If you plan to use a 450r rear shock then use the 450r linkages. If you are going to use a 400ex shock then use the 400ex linkages.

[mmbintn]

Read my first post. "Everything" but the parts listed will fit to include all brake parts.

[childert79]

I'm wanting to use a 250r LSR Rotor hub and locknut on my 400ex axle with 450r brake setup. Does anyone know if a 250r rotor will work with the 450r brakes?

[mineralgrey01gt]

go in the 250r section under the stickies, there is a thread on using 450r rear caliper and such on 250r's. See if that helps

[childert79]

Thanks for the reply. Just read it and it ended with someone asking if the 250r rotor would work with the 450 rear caliper. It seems that the only problem they had was with spacing but I would be using the 400ex rear carrier so my spacing would be different. Guess the only way to find out is to try it. I'll wait until monday to buy the 250r rotor in case someone posts up.

is that the 400ex sprocket hub your talking about?

can u put the 400ex rear sprocket holder on the 450r axle?

i have the 450r axle as well as swingarm and carrier and i'm getting ready to do this swapout.

I assume a 400ex sprocket hub will work on a 450r axle but not 100% sure. It definitely is not easy pressing those off. You almost need a pneumatic hydraulic press.

Let us know how it goes if you try the 450r axle.

[chronicsmoke]

I'm still in the process of making this swap.. Just got the swinger back from powder and got the bearings pressed in today. The axle from my 450r that I'm putting into my ex has different splines for the sprocket holder, but it is also durablue.. not to sure about stock. If it doesnt line up tomorrow when i try and put it together then ill take some pics and post it hee. I'm using the following parts from my 450r;

Swinger
Axle
Carrier
Shock
Linkage- (Probably use the 400ex link)
Brake caliper
Brake rotor & hub
Brake line

[2001400exrida]

that axle pivot bolt is a real PIA! i can't get mine to push out, it will turn but it won't push out. tomorrow we are gonna use a plasma cutter to cut the damm bolt or the swingarm, whatever it takes!

[CJM]

Any of you tried an air hammer yet? If I ever attempt to remove mine thats what Im using. But I SURE as hell am not removing it till I have every part needed cause it could be the end of the swinger.

Actually, you are going to bend the frame before you damage the swinger. All the bearings will float right through both holes in the swinger. What actually gets seized is the sleeve/collar that rides on the swingarm bolt.

[2001400exrida]

i think what he was saying is that he may have to cut the swinger off. just like what i'm going to have to do. the fram will be fine, it only mounts on the frame flanges on the side, the other mount is the motor mount. The motor mount is the one you want to make sure you don't screw up.

my bolt is bent and that's why i'm gonna have to chop my swingarm today.

does anybody know where to get the metal spacer/bushing that goes with this pivot bolt? i bought the bolt but don't know where to find a replacement bushing.

Sleeve comes in the swingarm bearing replacement kit...unless you buy genuine Honda parts then you can buy just the sleeves.

[2001400exrida]

i'm having trouble finding the sleeve even.
