Vortex 255A-41 Silver 41-Tooth 525-Pitch Aluminum Rear Sprocket

The Vortex 255A-41 is a silver, 41-tooth aluminum rear sprocket designed for motorcycles running a 525-pitch chain. Engineered by Vortex Racing — a U.S.-based manufacturer with deep roots in professional motorsport — this sprocket delivers a precise combination of lightweight performance and long-lasting durability.

Constructed from 7075-T6 billet aluminum and finished with a bright silver anodize, the 255A-41 reduces rotating mass compared to steel alternatives, contributing to improved throttle response, faster acceleration, and quicker directional changes. The sprocket features Vortex's patented saber tooth groove design, which is engineered to extend sprocket life by managing chain wear more effectively than conventional tooth profiles.

Key Features:

• 41 teeth — 525 pitch rear sprocket
• 7075-T6 billet aluminum construction for lightweight strength
• Silver anodized finish for corrosion resistance and clean appearance
