i know u guys have scene this bout 1000 times but every day somthing new happens i was wondering wich one would win in drag races sand dirt whatever stock and with mods thank you

 

Some friends of mine have (2) different Yama 450s - one completely stock and another with GYTR pipe and cam .. and 13tooth gearing

I raced the modified 450 up the sand dunes in CA over and over - and they are very very close. Even the guy riding the Yamaha said it was close.
I raced the stock one up - and kicked his bootie every time - of course, i didnt race mine stock - so maybe some difference.

we also drag raced down about 3 mile strectch.. amazingly, we were alot closer here.. the first 3 gears i was in front - but after 4th - Yamaha revs higher and it does catch up very very slowly - iI may add. I had the GPS with me and we both finished up at slightly over 75mph - but thats prob because it was loose sand - on extremely hard pack - im sure its closer to 80 !

HOWEVER,

TORQUE POWER - now way YAMAHA. Raced up a very steep sand dune - both of us in 2-3rd gear going straight up --- guess what Yamaha had 4 lenght head start - everytime i caught up to it and passed it.
that translates to low end torque/power - which is where most people ride --- in trailes or dunes...
the Yama riders were very UNBIASED ! AND even they said - Hey were' "TIED' for first place ! Only on the drag strip was it obvious that the Yama450 was slightly faster.

ALL i can tell you is this - they are soooooo fast - and so close - its all a matter of color.
I PREFER RED !!!

Get the 450

 

Both r pretty good atv's i heard the yamaha dosent come up that easy where its built for motorcross.And i heard the honda 450R is geared to high.But the honda looks pretty meanit probably dont have the power of the yamaha but i like the honda it looks cool.

 

i also heard the new 450 honda aint no different than the honda 400ex in power wise.

 

look in the yamaha fourm, there are alot of comparissions about the 2.

 

you can believe all that BS - but Ripper - this AINT no 400ex !
I had one for 4yrs - and I can tell you thats just the die-hard Yamaha fans talking.

BTW, I forgot to mention if you dont mind the engine knocking all over the place - get Team Blue.

If you want smooth consistent power all over the powerband, then forget about it - HONDA did a good job on this.
Much better job than Yamaha in my opinion.

and after this last wknd after spending some time riding with Team Blue - I ALSO got to drive the Y -- I was convinced that I made the right decision.

Like i said, its a matter of taste - but if you havent riden this - im telling you its so much faster than the last generation of ATV's-- that when I hear people say that its nothing but a 400ex -- they are completely 'wacked'.

Both bikes are good - and very very close - especially once you put your basic pipe/rejetting - they are almost the same - except for

comfort
quality
ergonomics
powerband
color
size/fit for the rider...

other than that -- GET WHATEVER color you prefer.

 

my friend has a yfz its completely stock rit now except fer handlebars and grips i think he said hes getting a hmf pipe gyr air filter and maybe a cam but if i get my trx i am going to get the hrc kit and a toomey exhaust which is suposed to take the stock 35 hp and make it 46(just the pipe alown) and a set of nerfz handle bars of course cuz its a honda k&n filter and a 13 front sprocket who do u think would win in any type of riding o and also i might get the z-brake auto clutch if i notice it stalls alot and also this kid that has the yfz is really rich sooo his posibilitys will neva end soo wats a short cut i could take to get there w/ him its not a matter of money just saving for itbut i dont want to bore it out or port it cuz then i cant ride it till it gets bak from who eva i have do it

 

TT racing is all about horsepower, always has been, always will be. I've raced 3 nationals this year and can tell you this. They are close... very close. If both machines had just a pipe both machines power is equil, however the honda does have more of a "tractable" powerband, the yamaha seems pipey. This week at paducah it was very slick... I could gain on most yamahas through the infield, but they would gain on me down the straight. But these gains did not make or break the race. In a good riders hands, with the right setup, both machines are potent TT weapons. But we will see after a couple of years how reliable both machine are... I think RED will privale!!!!!

 

i never raced them back to back, but from what ive experienced by what it has raced and i have raced i think both stock would be even. the yfz barely beats my predator and i think the 450r will beat it also because i beat a 416ex by more than the predator did. so ur getting a toomey pipe for a 450r huh 2phast....
