Vortex 635ZK-53 CAT5 Aluminum Rear Sprocket 53-Tooth

The Vortex 635ZK-53 is a 53-tooth CAT5 aluminum rear sprocket designed for high-performance motorcycle applications. Engineered to exacting standards, this sprocket delivers the precision fit and durability that Vortex Racing is known for across road racing, track days, and aggressive street riding.

Key Features:

• 53-tooth rear sprocket for modified gear ratio tuning
• Constructed from lightweight aerospace-grade aluminum to reduce rotational mass and improve power transfer
• Features a hard-coat anodized black finish for enhanced corrosion resistance and long service life
• Precision CNC-machined to tight tolerances for true concentricity and smooth chain engagement
• Optimized tooth profile for consistent chain wear and reliable power delivery

Upgrading to a higher tooth-count rear sprocket increases the drive ratio, resulting in improved low-end torque and acceleration. This sprocket is a direct bolt-on replacement designed to work with the matching chain pitch for the intended application. It is an ideal choice for riders looking to fine-tune their motorcycle's gearing for track use or spirited street riding.
