Vortex 839AV4-48 VTX Aluminum Rear Sprocket 48-Tooth Silver

The Vortex 839AV4-48 is a 48-tooth aluminum rear sprocket engineered for serious motorcycle racing applications. CNC-machined 100% in the USA from a specially formulated aerospace-grade aluminum alloy developed to Vortex's own exacting standards, this sprocket delivers an ideal balance of low rotating mass and exceptional durability.

The silver anodized finish provides corrosion resistance while the patented Vortex tooth profile is engineered to extend sprocket life and maintain smooth, consistent chain engagement lap after lap. Reducing unsprung and rotating weight over a stock steel sprocket directly improves throttle response, acceleration, deceleration, and mid-corner directional changes.
