Vortex 610ZK-41 CAT5 Aluminum Rear Sprocket 520 Pitch 41-Tooth Black

The Vortex 610ZK-41 is a CAT5 aluminum rear sprocket featuring a 41-tooth count and 520 pitch chain compatibility, finished in a durable black anodized coating. Designed as a high-performance upgrade over heavy OEM steel sprockets, this sprocket delivers a noticeable reduction in rotating mass for improved throttle response and acceleration.

Key Features:

• Lightweight CAT5 Aluminum Construction: Machined from a specially formulated alloy per Vortex specifications, combining strength with significant weight savings over stock steel sprockets
• 100% CNC Machined in the USA: Precision-machined to tight tolerances for perfect concentricity, reducing wear on both the sprocket and chain
• Black Anodized Finish: Cat 5 anodized black finish provides corrosion resistance and a clean, aggressive appearance
• Patented Saber Tooth Groove Design: Vortex's unique tooth geometry reduces drag and friction, improving both acceleration and deceleration performance while extending sprocket longevity
• Mud Grooves: Integrated mud-clearing grooves help keep the sprocket free of debris during aggressive riding
• 520 Pitch Compatibility: Designed for use with standard 520 pitch chains — a popular choice for OEM replacement or performance chain conversions
• 41 Teeth: Stock or modified gearing option depending on application

Vortex sprockets are a proven choice for both street and off-road riders seeking a performance-oriented replacement that outlasts and outperforms standard OEM components. The 610ZK series is manufactured to exacting standards and reflects Vortex's commitment to race-proven quality.
