just curious if in stock form it should be faster than a built 440,
i know stock suspension should not compare if you have total aftermarket but still just curious

I think it will be close if the 440 is 12:1 or higher and has all the goodies. Anything less and the EX will probably get smoked.

now this is just my thoughts but depending on builder,now i would hope a backyard build and a duncan would be a little different but i would expect the 450r to be faster?
just me or why would pros switch to the 450 dirtbike motor over a built 440?

I hope that it is as fast as a built 440 with 12:1 compression other wise you will be smoked by a stock yfz:devil: lolllllll

just kidin' of course it will be faster. look the ex is nice and it worked great for me but it is no where near the spec that the trx and the yfz just face it the 400 ex in any state of mod will not be able to keep up. I know I have a built 440 and it works great but just not the proformance of the yfz. TRX will be the same

My buddy has a built 440 with a cam, high compression piston, carb, etc, etc, etc. He runs race fuel in it. My YFZ with the baffle removed spanks it, so yes, I would expect the TRX to be better than a built 440.

Liquid cooled makes a big difference IMO.

If it wont outpower 99% of all 400exs motorwise dont bother bringing it to the race with the YFZs...My Stock YFZ is faster than my built 426EX as in there was no comparison AT ALL. I imagine the honda will be the same ATLEAST.

yall must be talkin a drag race, cause if your takin mx come to fl and race were we can see.it comes down to rider and that is it. i have my 400 apart now buing built to a 440 so ill have a little extra hp. but before i tore it apart i could beat anything out there if the rider wasnt better than me. if he was as good you saw a very good race, if he was better and thing went good for him (no wrecks) he beat me. like i said it comes down to rider.

sorry jason I have to disagree with you
it is a combination of rider and bike that wins the race. If I was to give you an lt80 and tell you lets race, no matter how good you were you couldn't beat me, I hope you agree. :devil: Even if it was a 250ex same thing. anyway I do agree that on the track rider counts alot but with the proper bike a rider who has less talent can suceed against a rider with more talent.

THE BIKES HAVE TO BE CLOSE IN COMPARISON. YOU CANT COMPARE A LT80 TO A 400. BUT YOU CAN COMPARE A 400 TO A 450. LETS PUT TIM FARR ON A BONE STOCK 400 AND ME( I RACE A CLASS) ON A 450. I WOULD BET THE BIKE HE PROLLY BEATS ME. IM NO SLOUCH BUT I AINT NO PRO EITHER. IVE PLACED IN EVERY RACE EXEPT 2 AND THEY WERE BOTH ON ACCOUNT OF DNF.NOW LETS PUT A GUY FROM A OR B CLASS ON THE SAME 450 AND ME ON MY 440 AND IT WILL COME DOWN TO RIDER.LIKE IT OR NOT JUST BECAUSE THE NEW 450'S ARE OUT THAT DONT MAKE THE 400 ANY LESS OF A QUAD. THEY ARE STILL TO BE NOTICED AND I HOPE THEIR MORE PEOPLE LIKE ME THAT ARE GOING TO SHOW ALMOST EVERYONE OUT THERE THAT RAN OUT AND WASTED THEIR MONEY ON NEW 450'S THAT A 400 CAN AND WILL BEAT THEM. I PLAN ON RACING THE GNC MX AT ECHECONNEE THIS YEAR IF EVERYTHING GOES AS PLANNED. ILL SEE YOU GUYS THERE.

YOU OWN A YFZ 450 OF COURSE YOUR GONNA THINK ITS A BETTER QUAD NO MATTER WHATS DONE TO A 400. YOUR NOT GONNA ADMIT AN OLD AIRCOOLED 400 WILL BEAT YOU.YOU WASTED 6,800 .

Jason, I had an 18K dollar 400ex, yes eighteen thousand. It was okay. I got a yfz now and when i go to the races and see the bike i can guess whos gonna be up front by looking at there bikes. If its not a cdale 250r yfz or crf, i dont worry about it. Its just so much time you can save out of every corner on the YFZ (OR NEW TRX) that the EX cant keep up. Maybe i did waste 6,800(thats just gonna get you stock) or maybe it was more like 13,000 but i dont think ill see to many 400exs in front of me next year, i sure didnt last year!

400ex: trail bike, New Generation 450s: race bikes

Guys dont get me wrong the 400ex can still race comp. especially in XC.

I can tell you that I used to race a Raptor and got beat by quite a few people (Z400's, 400EX's, 250R's, etc.) and I also beat all those bikes, then I got my YFZ, still the same person and I place about three spots better now on average, I used to be middle of the pack, now I'm in the bottom of the top third. It definitely made me faster, so yes bike does matter. I know that you are going to say a Raptor sucks and that's why, so I should also mention that I raced a KFX 400 that I still have and I was not any faster on it than I was on my Raptor. I still stand on my opinion that the TRX450 will be a faster bike than a built EX no matter who you are.

10-22-2003, 03:27 PM
yea but what did u have done to your raptor, a slightly modded ex or raptured cant compare to a stock yfz, a moddeed ex u will do ok, you just have to be 2 times better rider to go fast on a ex

hahaha wasted my money you crack me up. your the one wasting all that money on your 400ex when even with all those mods you wouldn't be able to pass a decent rider on a 450 trx or yfz. If you have stock suspension there is no way you can even compare to a trx or yfz sorry but you are full of it. I didn't say that the 400ex is not a good bike but it just isn't good enough for the competition that is why honda came up with the 450r. and with all the mods you will have in to your 400ex my yfz or a trx will kill it and I do wish you lived closer so I could show you real racing.

Both my KFX and Raptor were bone stock as well as my YFZ. So they are all stock to stock comparisons. I wish I had the money to mod them, but I don't, thus the reasoning for buying the YFZ, I don't have to mod it to be competitive in the beginner class.
