So I bought my first dirt bike for 600 bucks! It was raced a while back and my friend got it from the kid who raced. My friend had it bored over a little. Anyways, was curious to know if anyone has any experience with different sprockets on cr80's? I like doing wheelies so I was considering going smaller on the front sprocket. But I am also curious as to what kind of speed an 80 could be geared up to.
