Posted September 13, 20159 yr I have bought a tzr50, that has engine and carb upgrades. It's top speed is around 60. This is a problem as I am only 16, meaning I need to reduce its top speed. I was hoping to do this by just adding a larger rear sprocket on the bike, but it seems I am unable to find any online. If anyone knows any other ways to reduce the top speed cheaply or any links to a 52ish tooth rear sprocket.
September 20, 20159 yr I'd take the old sprocket to somewhere who supplies them for motocrossers , they should be able to match something up for you .
