Judging from your logo, I would guess you have already made your mind up??? For the kind of riding you described, I would suggest the YFZ.

I think the YFZ has the better engine, but for the kind of riding most people do (most bikes will NEVER see an MX track), the TRX has the better frame. Most people are trail riders.

 

I wouldn't trust any dyno's. One way to find out go out and race em' or watch them race.

 

I THINK THE 2 QUADS ARE PRETTY EQUAL BUT THE YFZ IS A LITTLE QUICKER WHEN I SAW BOTH OF THEM RACING IT ALL DEPENED ON WHO GOT THE HOLESHOT THAT QUAD WOULD WIN MOST OF THE TIME
