FULL DESCRIPTION
Renthal Ultralite Rear Sprocket - Silver
Upgrade your motorcycle's performance and durability with the Renthal Ultralite Rear Sprocket. This sprocket is engineered for superior longevity and is the ideal choice for both road and road racing applications.
Crafted from high-strength 7075 T6 aluminum, the same material used in Renthal's renowned offroad chainwheels, this sprocket offers exceptional strength and lightness. The Ultralite design contributes to reduced unsprung weight, potentially improving acceleration and handling.
A key feature of this sprocket is its hard anodized finish. This advanced surface treatment significantly enhances the hardness and wear resistance of the sprocket, providing increased longevity compared to standard sprockets. The hard anodizing process creates an integral surface coating that withstands the demands of rigorous riding.
