This kit will replace your stock sprocket bolts, nuts and keepers with new hardware.

Many aftermarket sprockets are thinner where they bolt to the wheel and the threads on the stock bolts do not allow these sprockets to be tightened down all the way. These grade 10.9 bolts will alleviate that problem. They are the same length as the stock ones, but the threaded area is longer allowing stock sprockets or aftermarket sprockets to be securely tightened down.

The bolt keepers are genuine Yamaha replacement parts to ensure an accurate fit. It's a perfect upgrade if your keepers have been removed too many times.

This spring clip retainer takes the place of the OEM two bolt retainer and fasteners when a FRITZCO sprocket is used.

All sizes of new FRITZCO sprockets come with a quick change retainer included, this is only a replacement.

This retainer can only be used with FRITZCO sprockets and can not be used with thin OEM type sprockets.

FRITZCO front sprockets are a straight up no hassle installation. Their sprockets are machined from alloy steel that in every way is comparable to OEM Yamaha and the best offered by other manufactures. The sprockets are then given a heat treatment that provides a compatible sprocket for the Yamaha output shaft and longest chain wear life possible.

High quality sprockets

• Stock size is 14 tooth
• Add teeth for highway riding
• Subtract teeth for low end gearing

Counter shaft sprocket replacement requires the removal of the left side case cover. A new gasket may be required. This is also a great time to replace that leaking oil seal!

• Use a rear sprocket with a higher number of teeth for quicker acceleration and technical offroad trails.
• Use a rear sprocket with a lower number of teeth for lower engine rpm's at highway speeds.
• Stock size is 50 teeth.

We recommend using the Rear Sprocket Bolt Kit when installing most aftermarket sprockets on your TW.
