"Hello everyone. Today I bought a 60cc Cylinder kit for my bike. It has the kit, bi-turbo and gears. I rode it home and was scared to ride it, it went alot faster. I later went to the bike store and bought a mountain bike speedometer.<br>I clocked on it going 54mph on flatland. If anyone is debating about the 60cc kit get it, its worth it?<br>"
