is this normal?

[ae13291]

ok guys i know the honda trx 450r is pretty damm fast, but it also seems very torquey. but is it normal to be pretty even in a race with a 450r and a 400ex? i drove the 450 and it has alot more torque then a stock 400ex. so today we went riding and i was racing against a 07 450 on a dry lake and we started in about 3rd gear and i punched it first and we were going dead even, towards the end of 5th he was barely inching away from me. i have the current mods in my sig and he had uni filter,modified airbox and stock modified muffler and new jetting. this is the 2nd 450 that i have literally kept up even with. i was surprised at how the 400 put up. has anybody else raced a 06 and newer 450r?

[buck440]

lol, :rolleyes:

[jcs003]

maybe the guy on the 450 had a thumb cramp.

[ngates788]

the 450r rider didnt change sprockets or anything? lower in front and higher in rear increases torque and lowers the speed. i think 15,38 is stock for the 450r's? not sure but im sure someone on here can tell ya

Something must be up. Sounds like you know the 400ex better than he knows the 450r. From a standing still launch its easy to believe but from a 3rd gear roll the 450 should have pulled away when you hit 5th. Racing a 450 in a drag from a roll quads were almost dead even the 400ex hanging there until it hit 5th and then the 450 hit the next gear and just kept pulling

[Gibson]

i believe it, i can get my brother's 04 450R on take off and he catches me when i hit 4th, but he never gets more than a 1/2 quad length in front of me after we top out.

[sprayedgt]

Either the 450 rider couldn't drive or something is up with his machine. Taking the launch out of the equation both riders ability should have been equal. Unless he weighs 500 lbs or something. I know with my '08 400 with the mods I have in my sig, a stock 450 will eat me on the top end with a 3rd gear roll.

[ae13291]

i knew i would get some type of crap from some people opening up a thread like this, anyways. so the 450 rider wighed probably 150lbs and im about 270lbs, so im alot heavier on a 400ex. the 450r rider was good and knew what he was doing but i mean we started in 3rd gear so that doesent matter. but i have the mods in my sig and the 450r was basically stock. when i drove his quad it is easily has more torque then my quad by alot.

[sprayedgt]

I would say that with your mods you may have 2 or 3 more hp than stock at the absolute most which would give you about 37 hp. His totally stock makes 43hp and with the little he has done maybe 2 more than that. The difference is not if his feels like it has more torque. It's that the 450 LIVES to be in the upper RPM range and excels in that range where in the same RPM range the 400 runs out of breath quickly. All I'm saying is next time you do this, make a video. It's a pretty hard battle proving you did something on a site that is loaded with people that have run into the same exact situation as you and came out with much less spectacular results. What makes it even harder to believe is that you are at a much, much heavier weight on the 400 with less power than he is on the 450. Which brings me back to thinking something is not in tune on the 450. Not flaming you, but something seems funny here.

man, i'd kill to have 37 hp with stock compression :blah:

i was thinking the same thing i dont even think my 416 11 to 1 makes 37hp

[Pipeless416]

37 hp from a 400ex usually requires high comp, valve work and porting, carb, cam, and exhaust.

[dariusld]

Iv'e raced my friends piped 450 and were about dead even.

[buster024]

All this only makes sense if the 450's sprockets were changed. I can pull my friend's piped 05 (I think it's an 05) on my 400, BUT he has changed sprockets (and so have I). I've pulled him on top end by a smidge several times, although off the line it's not even close....and my bike is well maintained, and his was purchased recently used, and we're not sure of the service history.

[Young_Gun1]

its all gearing he has a 14t front and i think stock is 13 one tooth in the front is a big difference

[sprayedgt]

Which is why I said the absolute most it would have would be 3 or 4 more than stock. I was being very, VERY generous.

[Pipeless416]

3 or 4 extra would still put you at about 30-31 hp.

[ae13291]

^^^^ it just so happened that there was a dry lake bed in front of us and i just decided to punch it, its not so hard to beleive, drag racing and track type of racing is complety different since no 2 people ride the same. but i really dident think it was that hard to believe the 400ex can hang in there with the 450 on a drag, i was pretty even with another 07 450 b4 i had even done my cam. the people who have rn against a 450r before know what i am talking about

[ngates788]

stock 400ex is 29hp or pretty close too it but the stock hp on a 450r is 37ish...

[ae13291]

i thought it was more?

[ngates788]

stock for stock there is a huge difference between the two but i looked into it before i installed my big bore in my 400 just for the comparison factor becuase my couisn has a 450.

All of you guys are smoking crack.

A stock 400ex is around 26hp. MAYBE 27hp if the motor came perfect out of the factory. A stock 450r is give or take 36-37hp.

Piped/jetted 400ex... ehh maybe 29hp max. Piped/jetted 450r is around the 42hp ball park

What is up with you guys and drag racing? Drag racing proves absolutely nothing. Go to a track and race, guarantee the 400ex will get killed. I am not bashing the 400ex but come on guys. I know you want to feel good about your trail quads and all but seriously? I will admit that I draged raced a few times and a kid with a bone stock 400ex couldnt come anywhere close to my 450 when it was stock. I am talking like completly smoked. I do not understand why people always want to drag race on their 400s and 700 craptors.

i'll challenge you to a race. any race you want, drag, xc, mx, tt and we will see how that goes.

[sprayedgt]

Direct from the Air Resource Board the 400ex puts out 34.19hp and the 450 puts out 42.65hp. These are the stock numbers at the crank and converting the KW rating into HP.

[droppedmazda]

im not goin to argue but i'll race any 450 built or not for $500 a race on my little 400ex.

crank hp to rwhp is as an apple is to an orange.

I'm sure more than one person on here would be more than happy to take your money from you with that offer.

beat me to it:cool:

Theres quite a loss by the time it gets to the rear wheels. The warriors say 28hp on the title.. which is a crank reading. whats that tell ya guys. lol.

That I know. I stated BOTH as crank ratings and not rwhp ratings. Both machines will lose near the same in drivetrain friction. The 450 looses slightly less because of internal differences.

wow thats crazy, must have a really fixed up 400 or 460 or 500

[sprayedgt]

Wonder what he'll do if some of the people with 450's and R1 motors call his bluff.

something like this.. :p

[droppedmazda]

r1 motors are not 450 based but ill gladly line up against any 450 based bike for $500 a pass. there r some for 450s that are gonna beat me but ill still line up just because i said i would. only reason i said anything is because some of the people on here act like there's nothing u can do to a 400ex to beat a piped 450 but i have 2 that will beat plenty of 450s.

HAHA!! That's priceless!! There's one in my garage right now that I'm building that I know you'll beat. It's on jack stands right now and the engine is out of it:blah:

[hypersnyper6947]

If a 450r puts 42hp at the crank and my 416ex puts 37hp to the wheels i would have to say it is possible to keep up with a 450, i have never had the pleasure of trying but i have dyno charts to prove my 37hp.

[sprayedgt]

He on his 400 is around 680lbs. The other guy on the 450 is about 530lbs. That's what makes it so unbelievable. If it were the other way around, with the heavier person on the 450, it would be an easier point to prove. Power to weight here is so much in favor of the 450 it's not even funny.

So the guy on the 400 weighs 270lbs, and the guy on the 450 weighs 150lbs, doesnt sound very good for the 400 at all your right.

yall go at it again but, this time have a camera handy. ;)

Hey man I'm heading to Sand Hill ATV March 20th or 21st. You interested?

[quad2xtreme]

My wife is proud of herself for beating me in drags with her 2008 450r over my 2000 and 2001 400ex(s). She wins by 1-2 lengths 90% of the time. When we switch though, I kill her by 10-15 lengths 100% of the time.

[86 Quad R]

yea? lemme check things out. i have yet to swap engines in my R from last seasons "grenade" but if all else fails i can always run my sons. i'll know more soon. :cool:

damn for that kinda of bet maybe I should buy a 450r and do a little work and after I win $500 thats money off the mods or the price.

[rideracelivemx7]

he had to of had a throttle cam or something becuase, well i know this is completely differerent but my ex built had absolutely NOTHING on my crf450 when i got it, it just flat out ripped and all it had was an hmf can on it, not even jetting or anything, and your bike had absolutely nothing that was on my ex and my ex would never have dreamed of seeing the acceleration that the stock 450 does. im not sure what he did to his but my ex has wayyy more torque than the 450 soo... last time i checked the 450 was about 46 at the crank on the trx

[ae13291]

i want to see how my quad wll do up against another 400ex ;) i dont have a helmet camera but if i do go there again and have the opportunity to go full throttle in 5th then i will do it to show you guys.

[quadrider1299]

Well ae13291 plain and simple your 400 is faster than a 450. I'm gonna call you GNCC 3. CM and RP will understand.
