Vortex 720-57 Rear Sprocket Chain Pitch Sprockets - 57-Tooth 520

The Vortex 720-57 is a 57-tooth rear sprocket designed for high-performance motorcycle applications. Engineered by Vortex Racing, a trusted name in motorsport components, this sprocket delivers the durability and precision tolerances demanded by both track and street riders.

Key Features:

• 57-Tooth rear sprocket for increased low-end torque and acceleration
• Precision-machined from high-strength aluminum or steel for lasting performance
• Compatible with 520 chain pitch applications
• Lightweight construction reduces unsprung rotational mass
• Hard-anodized finish (aluminum versions) resists corrosion and wear
• Manufactured to tight tolerances for smooth, consistent power transfer

Vortex sprockets are a popular upgrade for riders looking to fine-tune their final drive gearing. A higher tooth count like 57T provides stronger acceleration and improved low-speed power delivery, making it ideal for tight, technical circuits or urban riding. Always replace the front sprocket and drive chain when installing a new rear sprocket for optimal performance and longevity.
