2006 Honda TRX450R ( Kick Start )

How do you make the 2005 Pro Quad Champion, ATVA GNC MX Champion, and Baja Champion even better? How about a new engine with even more power? How about new suspension settings and steering geometry? How about two versions; kick start or electric start? That’s the new 2006 TRX450R. The best sport ATV we’ve ever made - quite a bold statement, considering Honda has dominated the class.

Honda. (that’s all I got to say about those pieces of crap)

Yamaha Raptors and YFZ’s both whoop ass!!! My 660 spanks my buddy’s modded 450r!! And I have seen multiple YFZ’s spank Honda 450’s as well. Wake up people.......Honda’s ass. Lose your pride because you know the truth......you will lose and you do lose. I know the truth hurts but don’t be mad at me. I am just here to let the truth be known.

dubz you are right the yfz 450 would out run the trx 450 any ing day my buddy has a trx 450 that is bored and piped and him and a yfz shock raced and the stock killed the trx by about a mile and would of went way past that if they would of went that long

Ran the 450r *stock at the beach in florence oregon wide open. According to my Garmin GPS the Honda had a top speed of 71.2mph. I am 225lbs

my 450r does about 180mph in 1/8 mile and 210 mph in 1/4 mile

man the trx450r is the it will kill the yamaha yfz450 eny day and what is the top speed on the trx450r

Someone needs to race me I got a 450r that i know will out run a yzf450 anyday

whos the dumbass that said his quad would go 180? hes a douche bag.

i have a honda 450 and it goes 180 mph in a quarter mile

stock vs. stock the yfz will win, but with equal riders.
