cgibbons99 Posted September 13, 2015 Share Posted September 13, 2015 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. Link to comment Share on other sites More sharing options...

KevtheRev Posted September 20, 2015 Share Posted September 20, 2015 I'd take the old sprocket to somewhere who supplies them for motocrossers , they should be able to match something up for you . Link to comment Share on other sites More sharing options...
