I was kind of bummed out after i took out my 400EX for the first ride with my Razrs on. To tell you the truth, my old worn out stock tires hooked up just as good as the Razrs on the same trails. I also put on a 16 tooth front sprocket and i was able to get 76.5 mph on my GPS. Keep in mind, it is not stock, but 76.5 isn't too bad.

 

Hey What did that 16 inch sprocket do. did u lose or gain bottom end. did u lose any mid and did u gain top end

 

To tell you the truth, i didn't lose any lowend power. The power felt about the same in the first four gears. Where i noticed the difference was in fifth gear. With the stock gearing i was bouncing off the rev-limiter on top-end. With the 16 tooth sprocket, i haven't hit the rev-limiter yet and i picked up about 4 mph on top end.
