Vortex 193A-45 Silver 45-Tooth 520-Pitch Aluminum Rear Sprocket

The Vortex 193A-45 is a 45-tooth, 520-pitch rear sprocket designed for riders who demand lightweight performance without sacrificing durability. Engineered as a 520 chain conversion sprocket, it is an ideal upgrade for motorcycles originally equipped with heavier 525 or 530 chain setups, reducing overall drivetrain weight for improved throttle response and acceleration.

CNC machined in the USA from a specially formulated aluminum alloy per Vortex specifications, this sprocket delivers the precision and consistency that racers and performance street riders rely on. The silver anodized finish provides corrosion resistance and a clean, aggressive look. The body is cupped down from the tooth ring to minimize weight while maintaining structural integrity.
