Vortex 527ZR-54 CAT5 530 Rear Sprocket Red 54-Tooth Aluminum

The Vortex 527ZR-54 is a CAT5 Series 54-tooth rear sprocket designed for 530-pitch chain applications on road motorcycles. Machined from aerospace-grade 7075 aluminum, it delivers a significant weight reduction over OEM steel sprockets, reducing rotating mass for improved acceleration and throttle response.

What sets the CAT5 series apart is Vortex's distinctive finishing process: each sprocket is color-anodized first, then CNC machined, resulting in a vibrant red finish with contrasting bright silver highlights on the sweeps, mud grooves, and tooth faces. The result is a race-proven component that looks as good as it performs.

Key Features:

• 530 Chain Pitch — 54-tooth rear sprocket for road applications
• 7075 T6 Aerospace Aluminum — premium alloy for optimal strength-to-weight ratio
• 100% CNC Machined in the U.S.A. — manufactured to the tightest tolerances for perfect concentricity
• CAT5 Color Anodizing — anodized before machining for a vibrant red finish with silver highlights
• Saber Tooth Groove Design — unique tooth geometry reduces friction, improves chain engagement, and extends sprocket life
• Reduced Rotating Mass — lighter than OEM steel, multiplying the benefit across all drive components
• Vortex Patented Design — trusted by racing champions on track and street

The 54-tooth count provides a higher drive ratio, optimizing low-end torque and acceleration. Vortex CAT5 sprockets are a proven upgrade for performance street riding and track day use, offering the reliability of race-bred engineering in a visually striking package.
