Stage III cam, Track porting, 11:1 piston, duals, filter kit and 15t front sprocket and youll be just over 90mph depending on weight.

Yamaha is sandbagging its figure.
Mine is stock as far as engine goes and I weigh 265 pounds. I've gone much faster than 76 miles-per-hour, according to the speedometer on my buddy's Grizzly, on wet sand.

I just installed Trail tech Vapor and my top speed was 73.5 mph. I have a 15 tooth front sprocket it's bone stock.
I was disapointed the RPMS would only go 6800. I guess the 15tooth front is a little to much for stock to pull any higher in the RPMS. I'm saving money for the three mods. All most have enough. :thumbsup:
