Grom, Dax, Monkey Street / Race / Stunt Regearing kit

Looking to regear your DAX, Grom, or monkey for better performance! 

Please use the drop down menu to select gear ratio, and your bike's year.

A larger rear sprocket or smaller front will increase acceleration.

A smaller rear sprocket or larger front sprocket will increase top speed.

NOTE : I see lots of kits using cheap low quality chains. These kits include an RK 420MXZ chain which will not wear and stretch out nearly as fast as the other kits I see. I went from adjusting my chain every ride and replacing my chain twice a year, to adjusting every 15-20 rides going from a cheap chain to this nice one. 

Kit includes :

• S3 Rear sprocket (Choose 37T or 40T) 
• JT Front Sprocket (Choose 14T or 15T)
• RK GB420MXZ Chain (120L) 

Pairs perfectly with our S3 chain adjusters
