Vortex 817ZB-46 Black Steel Rear Sprocket 46-Tooth

The Vortex 817ZB-46 is a 46-tooth black steel rear sprocket engineered for performance motorcycle applications. Manufactured in the USA to exacting tolerances, this sprocket delivers the durability and precision that Vortex Racing is known for among street and track riders alike.

Key Features:

• 46-tooth rear sprocket for tuned final drive gearing
• Carbon steel alloy construction per Vortex specifications for maximum strength and longevity
• Electro-plated satin black finish for corrosion resistance and aggressive styling
• 100% CNC manufactured in the USA for precise, concentric tolerances
• Vortex patented tooth profile — unique tooth geometry extends sprocket service life
• Quieter operation compared to non-precision alternatives due to concentric manufacturing

Upgrading to a higher-tooth-count rear sprocket like the 46T increases low-end torque and improves acceleration response, making it a popular choice for riders seeking stronger roll-on power. Always replace the front sprocket and chain together when installing a new rear sprocket for optimal performance and wear life.
