Vortex 245A-57 Aluminum Rear Sprocket 520 Pitch 57 Tooth Silver

The Vortex 245A-57 is a lightweight aluminum racing sprocket featuring 100% CNC manufacturing in the USA. This 57-tooth, 520-pitch rear sprocket is constructed from specially formulated alloy per Vortex specifications and silver anodized to prevent corrosion.

Key Features:

• Unique tooth design increases sprocket longevity
• Vortex patented sprocket design unlike any other sprocket
• Lightweight construction reduces rotating mass and aids in putting more power to the pavement
• 520 chain pitch compatibility
• Silver anodized finish for corrosion resistance
• Precision CNC machined for exact tolerances

This is a 520 conversion sprocket, meaning when switching to a different pitch size, all three components (front sprocket, rear sprocket & chain) must be the same pitch. The 245A series sprockets are designed for street sportbike applications and offer the perfect balance of weight savings and durability for performance riding.
