Vortex 313ZK-44 44-Tooth 520-Pitch Aluminum Rear Sprocket

The Vortex 313ZK-44 is a 44-tooth, 520-pitch aluminum rear sprocket engineered for motorcycle road racing and performance street riding. Vortex Racing has been manufacturing precision drivetrain components in the USA since 1995, and this sprocket reflects their commitment to tight tolerances and high-quality materials.

Key Features:

• 44 teeth — delivers increased rear-wheel torque and improved low-end acceleration over lower-tooth-count sprockets
• 520 chain pitch — compatible with 520-series chains for a broad range of sport and supersport motorcycles
• Lightweight aluminum construction — reduces rotating mass compared to OEM steel sprockets, improving throttle response and handling
• 100% CNC manufactured in the USA — machined to exacting tolerances using a specially formulated alloy per Vortex specifications
• Anodized finish — resists corrosion and wear for extended service life
• Vortex patented tooth design — unique geometry increases sprocket longevity and promotes smooth chain engagement

The Vortex 313ZK-44 is a direct-fit replacement and performance upgrade for riders looking to fine-tune their gearing. Always replace the front sprocket and chain simultaneously when installing a new rear sprocket to ensure even wear and optimal drivetrain performance.
