Vortex 641-54 Silver 54-Tooth 520-Pitch Aluminum Rear Sprocket

The Vortex 641-54 is a 54-tooth, 520-pitch silver aluminum rear sprocket engineered for high-performance street and stunt riding. Built from 7075 T6 billet aircraft-grade aluminum, this sprocket delivers an exceptional strength-to-weight ratio while dramatically reducing unsprung rotating mass compared to steel alternatives.

Vortex's proprietary saber tooth groove design and patented tooth profile set this sprocket apart from the competition, promoting extended sprocket life and smooth, consistent chain engagement under hard acceleration. Precision CNC machining ensures exact concentricity for vibration-free performance, and strategically placed lightening holes further reduce weight without sacrificing structural integrity.
