For real!! Why would you even ask such a question, being a pro racer and all??[img]i/expressions/face-icon-small-disgusted.gif[/img]

 

Get a YFZ much more explosive accelartion and top end speed best handiling on any qaud Ive seen in along time. It also has an electric start its a pain in the a$$ trying to kick start a big bore qaud like the TRX-450. If you dont kick the starting lever all the way down it will come back up and whack you in the ankle leaving a pretty good size bruze.You also have to the engine running very smoothly if you want the bike to start on the first or second kick. The TRX is a good qaud theres no question about that i would honestly go with YFZ for two reasons one eletric start and two more explosive accelration.

my buddy just bought a trx spent more money then i did on my yfz and i hand his *** to him in every way possible.
the onaly thing that i like about the trx is i can wheely for days on it other then that it sucks
also that foward kick start is pain in the nuts


so in my opinion the yfz hands down

 

If you are a big guy then the TRX will move you faster (better Torque) and fit you better. They are both awesome I just preferred the TRX 450R. YFZ was too small feeling for me, and I haven't really experienced this "wheelie problem", but that is probably cuz I am more used to riding my Big Bore 250R 3wheeler and you really have to work to keep the front wheel down on it! If you had good luck with Yamaha then get that, or with Honda then get that! I made my choice on all these considerations and it meant alot to me, my prior experience with Honda Products. Just get what fits you best.

The kickstart is so easy and thank goodness it is forward kick, I am very used to it!

 

If you are going to do more racing than riding get the yfz, but if its the other way around get the honda. My uncle has a yfz and its a great fast quad but the thump throttle will kill you on long rides
