sprockets

[gitrdonechevy25]

What sprocket combo should i go with for my top speed for my 450r. I have 20's on the back. Right now its stock gearing and I need more top end because my motor is very worked. I dont wanna put a 15 on front what combo should i put thanks.

go and type in atv gear calculator on your search engine and you'll find a site that breaks down top speed out of each gear with each sprocket combo.;)
