Vortex 422-66 Silver 66-Tooth Aluminum Rear Sprocket

The Vortex 422-66 is a 66-tooth aluminum rear sprocket finished in silver, designed as a custom replacement for off-road and motocross applications. Built to Vortex's exacting standards, this sprocket is 100% CNC machined from lightweight aluminum and features Vortex's patented tooth design for extended service life and reliable power transfer.

Vortex's unique tooth profile reduces wear and stress on both the sprocket and chain, helping this rear sprocket outlast the competition. The silver finish is achieved through a clear protective coating applied over the aluminum to resist oxidation and maintain appearance over time.

Key Features:

• 66-Tooth rear sprocket for aggressive low-end acceleration and torque-focused gearing
• Lightweight aluminum construction for reduced rotating mass
• 100% CNC machined for precise tolerances and consistent fit
• Vortex patented tooth design for increased sprocket longevity
• Silver anodized finish with clear protective coating
• Compatible with 520-pitch chain applications

A high tooth-count rear sprocket like the 422-66 is ideal for riders seeking improved low-end power delivery and quicker acceleration, particularly in off-road, trail, and motocross environments. Replacing your rear sprocket with the correct pitch and tooth count is essential — the front sprocket, rear sprocket, and chain must all share the same pitch for proper operation.
