If not we may be able to come up with some other alternatives for you so please contact us and we will see what we can do.

This sprocket is a 17 tooth, also available in 12, 13, 14, 15, 16 teeth please contact us for details.


This sprocket will fit these bikes as a direct replacement each bike is listed under the number of teeth that will maintain standard gearing. If you want to increase the speed of your bike we recommend you go for a bigger front sprocket please check out our shop for the listed sprockets. A smaller front sprocket gives more acceleration and LESS top speed. Bigger Front sprocket gives less acceleration but MORE TOP SPEED. But please bear in mind only if the engine has enough power.
