Designed to provide longevity and reliable handling without adding weight to the machine, this kit is suitable for urban use and small displacement bikes like the Aprilia 50.

The steel/aluminum combo reduces inertia while maintaining robustness at the sprocket. The XS-Rings extend the chain's lifespan by keeping internal lubrication intact.
