Vortex 610ZR-41 41-Tooth Red Aluminum Rear Sprocket

The Vortex 610ZR-41 is a 41-tooth red anodized aluminum rear sprocket engineered for performance motorcycle applications. Built to Vortex's exacting standards, this sprocket is 100% CNC machined in the U.S.A. from a specially formulated CAT5 aluminum alloy, delivering an outstanding strength-to-weight ratio over stock steel sprockets.

Vortex's signature saber tooth groove design sets this sprocket apart — the patented tooth profile reduces wear, extends service life, and promotes smooth, consistent chain engagement. Weight-reduction sweeps and mud grooves are machined throughout the face for reduced rotational mass, which translates directly to improved throttle response and drivetrain efficiency.

Key Features:

• 41 teeth — allows precise gear ratio tuning for acceleration or top-speed optimization
• Lightweight CAT5 aluminum construction — reduces unsprung and rotating mass compared to steel
• Red anodized finish — CAT5 anodizing provides corrosion resistance with a vivid red color and contrasting silver machined highlights
• Patented saber tooth groove design — increases sprocket longevity and promotes even chain wear
• 100% CNC manufactured in the U.S.A. — precision tolerances for reliable OEM-quality fitment
• Specially formulated alloy per Vortex specifications

The Vortex 610ZR-41 rear sprocket is an ideal upgrade for riders looking to fine-tune their gearing, reduce drivetrain weight, or refresh a worn OEM sprocket with a high-quality aftermarket alternative. Always replace the chain and front sprocket simultaneously for optimal performance and longevity.
