Vortex 422B-66 Black Steel 66-Tooth Rear Sprocket

The Vortex 422B-66 is a 66-tooth rear sprocket built for small-bore off-road and motocross motorcycles. Manufactured from carbon steel alloy to Vortex's exacting specifications, this sprocket delivers the strength and durability needed for aggressive trail riding, motocross, and low-speed technical terrain where a tall rear sprocket tooth count provides maximum low-end torque and pulling power.

Finished in a satin black electro-plated coating, the 422B-66 resists corrosion while giving your drivetrain a clean, aggressive appearance. Vortex's patented tooth profile is engineered to reduce chain wear and extend sprocket service life beyond conventional designs.

Key Features:

• 66-tooth count for enhanced low-end torque and acceleration
• 422 pitch chain compatibility — matches standard small-bore off-road chain sizing
• Carbon steel alloy construction per Vortex specifications for maximum durability
• Satin black electro-plated finish for corrosion resistance
• Vortex patented tooth design reduces chain wear and increases sprocket longevity
• Precision machined for accurate fitment and smooth chain engagement

The 422B-66 is an ideal upgrade for riders seeking lower gearing for woods, trail, or technical off-road use where torque and low-speed control are prioritized over top-end speed.
