Renthal 210U-520-48P-HA Ultralight Rear Sprocket 520 Chain Pitch 48T Hard Anodized

The Renthal 210U-520-48P-HA Ultralight Rear Sprocket is a precision-engineered 48-tooth rear chainwheel designed for 520-pitch motorcycle drive chains. Purpose-built for street and track day applications, this sprocket delivers a significant weight reduction and performance advantage over conventional steel sprockets.

Manufactured from specially enhanced 7075-T6 aluminum alloy, the Renthal Ultralight design is 66% lighter than steel while remaining incredibly durable. Each sprocket is CNC-machined to extremely tight tolerances, ensuring outstanding concentricity and accuracy of fit for maximum power transfer and extended service life.

A hard anodized surface finish is applied as an integral coating — not a surface treatment — which significantly increases hardness and wear resistance, giving this street-focused sprocket enhanced longevity compared to standard anodized aluminum sprockets.
