From my knowledge neither the trx450r or the yfz450 have reverse. To me that sucks, I'm not a diehard racer so i like reverse. To drop almost 7 grand and not even get reverse is pretty stupid. Thats why my next bike will be the kawi or suzuki. I know not as fast but at least everything was taken into consideration prior to production. I know the yammi and honda are great bikes (super fast, handle amazing, etc.) it just doesnt seem logical to not have a reverse gear on a quad I mean its not a dirtbike but i guess if you get the motor from one it means you cant have reverse or something. Well thats my 2 cents respond if I'm incorrect about anything.
