Vortex 780ZR-51 Aluminum Rear Sprocket 520 Pitch 51 Tooth

The Vortex 780ZR-51 is a 51-tooth, 520-pitch aluminum rear sprocket engineered for performance motorcycle applications. Built to the same exacting standards trusted by professional racing teams worldwide, this sprocket delivers an ideal balance of lightweight construction and long-lasting durability.

Key Features:

• 7075 T6 billet aluminum construction — aerospace-grade alloy for maximum strength-to-weight ratio
• 520 chain pitch — compatible with standard 520 chain setups
• 51-tooth rear sprocket — optimized for specific gearing requirements
• CNC machined in the USA — precision manufacturing ensures concentricity and consistent fit
• Lightening holes — strategically placed to reduce rotating mass without sacrificing structural integrity
• Clear anodized finish — resists corrosion and wear for extended service life
• Gunk-clearing tooth grooves — help shed debris and keep the drivetrain running cleanly

Vortex Racing rear sprockets are a proven choice for road racing, superbike, and street performance applications. Reducing rotating mass with a lightweight aluminum sprocket improves throttle response, acceleration, and overall drivetrain efficiency compared to heavier OEM steel sprockets.
