The Vortex 595-51 is a silver anodized, 51-tooth aluminum rear sprocket designed for 520-pitch chain applications. Built by Vortex Racing — a U.S.-based manufacturer with decades of motorsport experience — this sprocket is CNC-machined from a specially formulated aluminum alloy and engineered to deliver reliable performance for road racing, flat track, and high-performance street riding.

Key Features:

• 51-Tooth, 520 Chain Pitch — direct-fit replacement or gearing upgrade for 520-pitch drivetrain setups
