Vortex 201ZK-64 Aluminum Rear Sprocket 64-Tooth

The Vortex 201ZK-64 is a precision-machined aluminum rear sprocket featuring a 64-tooth configuration, designed for high-performance motorcycle applications. Engineered by Vortex Racing — a U.S.-based manufacturer with over 15 years of motorsport experience — this sprocket delivers race-proven reliability for road racing, supercross, motocross, and street performance use.

Key Features:

• 64-tooth rear sprocket for optimized gear ratio tuning
• Machined from aerospace-grade aluminum alloy for maximum strength-to-weight ratio
• Hard anodized finish for corrosion resistance and surface durability
• Precision CNC machined to tight tolerances for true concentricity and smooth chain engagement
• Lightening holes reduce rotating mass for improved throttle response
• Made in the USA by Vortex Racing

Vortex rear sprockets are manufactured to the same exacting standards used by professional race teams worldwide. The ZK carrier designation identifies the bolt pattern and hub fitment specific to compatible motorcycle applications. Adjusting to a higher tooth count like the 64T lowers overall gearing, improving low-end torque and acceleration — ideal for tight circuits or aggressive off-the-line performance.
