Vortex 512ZK-56 Aluminum Rear Sprocket 520 Pitch 56 Tooth

The Vortex 512ZK-56 is a high-performance aluminum rear sprocket designed for 520 pitch chain systems. This 56-tooth sprocket is precision CNC-machined from aerospace-grade 7075-T6 aluminum alloy, delivering exceptional strength while significantly reducing rotating mass compared to OEM steel sprockets.

Key Features:

• 520 pitch (5/12" pitch) for compatibility with 520 chain systems
• 56 teeth for precise gearing options
• CNC-machined from 7075-T6 billet aluminum for maximum strength-to-weight ratio
• Unique tooth design increases sprocket longevity and chain engagement
• Lightweight construction improves acceleration, deceleration, and handling
• Kawasaki bolt pattern (ZK designation)
• Made in the USA by Vortex Racing

Vortex Racing sprockets are trusted by professional racers in AMA Superbike, Motocross, and Road Racing competitions. Each sprocket is manufactured to the tightest tolerances in the industry, ensuring precise fit and optimal performance. The reduced weight of aluminum construction decreases rotational inertia, allowing for quicker throttle response and improved directional changes.
