Vortex 527ZR-41 CAT5 Red 41-Tooth 530-Pitch Rear Aluminum Sprocket

The Vortex 527ZR-41 is a CAT5 anodized aluminum rear sprocket featuring 41 teeth and a 530-pitch chain interface. Machined from a specially formulated aluminum alloy to Vortex's own specifications, this sprocket delivers a significant weight reduction over stock steel units — reducing rotating mass for improved throttle response and acceleration.

Key Features:

• CAT5 Red Anodized Finish — Vivid red color anodizing with contrasting silver machine-cut highlights on the sweeps and body
• Saber Tooth Groove Design — Vortex's patented tooth profile reduces drag, minimizes friction, and extends sprocket and chain service life
• 100% CNC Machined in the USA — Manufactured to the tightest tolerances for a perfectly concentric sprocket every time
• Specially Formulated Aluminum Alloy — Proprietary alloy per Vortex specifications balances light weight with durability
• 530 Chain Pitch — Direct replacement for 530-pitch drive systems
• 41 Rear Teeth — Stock-equivalent tooth count for OEM gearing ratio

Vortex CAT5 rear sprockets are a proven choice for street and track riders looking to reduce unsprung and rotating weight without sacrificing reliability. The anodized finish provides corrosion resistance while the distinctive color scheme adds a premium look to the drivetrain.
