Vortex 615BZB-48 Black 48-Tooth 615-Pitch Rear Sprocket

The Vortex 615BZB-48 is a 48-tooth, 615-pitch aluminum rear sprocket finished in a black hard-coat anodize. Engineered for performance-minded riders, this sprocket is 100% CNC machined in the USA from a specially formulated aluminum alloy to Vortex's exacting standards, delivering a lightweight alternative to the heavy OEM steel sprocket.

Key Features:

• Chain Pitch: 615
• Tooth Count: 48 teeth
• Finish: Black hard-coat anodized for corrosion resistance and a aggressive appearance
• 100% CNC manufactured in the USA to tight tolerances for a perfectly concentric sprocket
• Specially formulated aluminum alloy per Vortex specifications for optimal strength-to-weight ratio
• Vortex patented unique tooth design reduces friction, minimizes chain wear, and increases sprocket longevity
• Reduced rotating mass compared to stock steel sprockets aids in improved throttle response and acceleration
• Available in single-tooth increments for precise gearing customization

Upgrading to a higher tooth-count rear sprocket like the 48-tooth 615BZB delivers more low-end torque and quicker acceleration versus a stock lower-count sprocket. The black anodized finish not only resists corrosion but also gives the drivetrain a clean, blacked-out look. Trust Vortex Racing's decades of motorsport expertise for a sprocket that performs as good as it looks.
