Vortex 151ZR-56 CAT5 420 Rear Sprocket 56-Tooth Red Aluminum

The Vortex 151ZR-56 is a 56-tooth CAT5 rear sprocket designed for 420-pitch chain applications. Built for riders who demand lightweight performance without sacrificing durability, this sprocket is 100% CNC-machined in the U.S.A. from a specially formulated aluminum alloy and finished in a vibrant red anodize with contrasting silver machine cuts on the sweeps, mud grooves, and teeth.

Key Features:

• 420 pitch — engineered for small-displacement and mini-moto applications
• 56 teeth — higher tooth count for increased low-end torque and acceleration
• CAT5 aluminum construction — lightweight aerospace-grade alloy per Vortex specifications
• Patented saber tooth groove design — unique M-tooth profile increases sprocket longevity and wear resistance
• Red anodized finish — color anodizing provides corrosion resistance with bright silver highlighted accents
• 100% CNC manufactured in the U.S.A. — machined to tight tolerances for precise, concentric fitment
• Available in multiple colors (red, black, blue, gold) depending on application
