Vortex 505-55 Silver 55-Tooth Aluminum Rear Sprocket

The Vortex 505-55 is a silver, 55-tooth aluminum rear sprocket designed for high-performance motorcycle applications. Built to Vortex's exacting standards, this rear sprocket is precision-machined from 7075 T6 aluminum — the same high-grade material trusted by professional racers — delivering an ideal balance of lightweight construction and long-term durability.

Vortex's patented tooth profile is engineered to reduce wear on both the sprocket and chain, extending the service life of your entire drive system. Each sprocket is induction-hardened and plated to resist corrosion and withstand the demands of aggressive street and track riding.
