Vortex 641A-52 Aluminum Rear Sprocket 52 Tooth

The Vortex 641A-52 is a high-performance aluminum rear sprocket designed for sportbike and street motorcycle applications. This sprocket features 52 teeth and is precision-machined from 7075-T6 aircraft-grade aluminum alloy for an optimal balance of strength and weight reduction.

Key Features:

• 52-tooth configuration for improved acceleration and torque
• CNC-machined from 7075-T6 aluminum for lightweight durability
• Hard-anodized finish for extended wear resistance
• Self-cleaning mud grooves to prevent debris buildup
• Precision-cut teeth ensure smooth chain engagement
• Significantly lighter than steel sprockets for reduced rotating mass

Vortex sprockets are engineered to exacting tolerances and undergo rigorous quality control testing. The hard anodizing process extends sprocket life while the lightweight construction improves acceleration response and reduces strain on drive components. Compatible with standard 520, 525, or 530 pitch chains depending on application.
