Vortex 527ZR-43 CAT5 Red 43-Tooth 530-Pitch Rear Aluminum Sprocket

The Vortex 527ZR-43 is a CAT5 series aluminum rear sprocket engineered for high-performance motorcycle applications. Featuring a 530 chain pitch and 43 teeth, this sprocket is finished in an eye-catching anodized red with contrasting silver machine cuts on the sweeps, mud grooves, and tooth ring.

Vortex CAT5 sprockets are 100% CNC-machined in the USA from a specially formulated aluminum alloy developed to Vortex's own specifications. The result is a sprocket that delivers an outstanding balance of low weight, dimensional precision, and long service life — making it a popular upgrade from heavier OEM steel sprockets.

Key Features:

• CAT5 Lightweight Aluminum Construction — Specially formulated alloy per Vortex specifications for strength without excess weight
• 530 Chain Pitch — Designed for 530-series drive chains
• 43-Tooth Rear Sprocket — Optimizes final drive gearing for acceleration or top-speed tuning
• 100% CNC Manufactured in the USA — Machined to tight tolerances for precise concentricity and quiet operation
• Patented Saber Tooth Groove Design — Vortex's unique tooth geometry reduces friction, extends chain and sprocket life
• Anodized Red Finish — Color anodizing applied to the body with contrasting bright silver on the teeth and grooves
• Available in Four Colors — Red, blue, gold, and black (availability varies by application)

Upgrading to a Vortex CAT5 aluminum sprocket reduces rotating mass in the drivetrain, which translates directly to improved throttle response and acceleration. The precision CNC manufacturing process ensures a perfectly concentric sprocket every time, reducing drivetrain wear and freeing up horsepower.
