The Vortex 151ZR-48 is a CAT5 series 420-pitch, 48-tooth aluminum rear sprocket finished in red anodize with contrasting silver machine cuts. Designed for performance-minded riders, it delivers a significant weight reduction over OEM steel sprockets, reducing rotating mass for improved acceleration and throttle response.

Key Features:

• Lightweight CAT5 aluminum construction — machined from a specially formulated aerospace-grade alloy per Vortex specifications
• 100% CNC manufactured in the U.S.A. for precise tolerances and consistent quality
• Vortex patented saber tooth groove design — unique tooth profile engineered to increase sprocket longevity
• Color anodized finish — red anodizing applied before CNC machining leaves bright silver highlights on the sweeps, mud grooves, and teeth
• 420 chain pitch — designed for use with standard 420 chains common on smaller displacement motorcycles and minibikes
• 48 teeth — rear sprocket tooth count optimized for lower-end torque and acceleration

The Vortex CAT5 line is trusted by racers and enthusiasts alike for its combination of race-proven performance, durability, and eye-catching aesthetics. This sprocket is an ideal upgrade for riders looking to shed weight from their drivetrain without sacrificing reliability.
