I was very impressed with the Dyno numbers the trx was putting out!!!! I especially liked the torque mesurements. Go to www.gtthunder.com and click on 450R I have had my 450R for about two weeks now and I love the power and acceleration I get and was confused as to why everyone was talking about how the yfz was faster than the trx. I feel both bike are comparable in both power and speed its all up to who's the best riders....[img]i/expressions/face-icon-small-smile.gif[/img]
