Vortex 491-48 Silver 48-Tooth Rear Sprocket

The Vortex 491-48 is a silver, 48-tooth rear sprocket engineered for high-performance motorcycle applications. Machined from 7075 T6 billet aluminum, this sprocket delivers a significant weight savings over stock steel sprockets — reducing rotating mass and translating directly into improved acceleration and drivetrain responsiveness.

Vortex's patented saber-tooth groove design is 100% CNC machined to the tightest tolerances, producing a perfectly concentric sprocket every time. This precision fit minimizes drivetrain friction, extends both chain and sprocket life, and frees up horsepower. A clear anodized finish helps resist corrosion and gives the sprocket a clean, polished appearance.
