Vortex 151ZB-48 Black Anodized 48-Tooth Aluminum Rear Sprocket 520 Pitch

The Vortex 151ZB-48 is a 48-tooth, 520-pitch black anodized aluminum rear sprocket designed for performance motorcycle applications on the street and track. Manufactured 100% in the USA using a specially formulated aerospace-grade aluminum alloy, this sprocket delivers an exceptional balance of light weight and durability.

The black anodized finish provides corrosion resistance and a sleek, aggressive appearance, while Vortex's patented tooth profile is engineered to reduce wear and extend sprocket life beyond what standard designs offer. By replacing a heavier OEM steel sprocket, the 151ZB significantly reduces rotating mass, contributing to improved throttle response and overall drivetrain efficiency.
