I am just woundering how much horsepower a stock 07 yzf 450 has ?
You should be able search up dirtrider magazine online. They always dyno the bikes for their 450 shootout.
Reliable reports I have seen put well tuned examples of the '07 at 50.5-51 (rear wheel), which is about 0.5-1.0 more than an '06, and the same amount less than an '08.
