Vortex 617ZR-56 Red Aluminum Rear Sprocket 56-Tooth

The Vortex 617ZR-56 is a 56-tooth red anodized aluminum rear sprocket designed for performance motorcycle applications. CNC-machined in the USA from a specially formulated aluminum alloy, this sprocket delivers an optimal balance of lightweight performance and durability on street and track.

Key Features:

• 56-Tooth rear sprocket for tuned final drive gearing
• Red anodized finish (ZR designation) for corrosion resistance and a distinctive appearance
• 100% CNC manufactured in the USA to precise tolerances
• Specially formulated aluminum alloy per Vortex specifications
• Unique patented tooth design increases sprocket longevity
• Lightening holes reduce rotating mass for improved throttle response
• Reduces unsprung rotational weight compared to OEM steel sprockets

Vortex Racing rear sprockets are a trusted choice among road racers and performance riders. The higher 56-tooth count shifts the final drive ratio toward greater low-end acceleration and increased torque to the rear wheel. Always replace the front sprocket and chain simultaneously for optimal wear and performance.
