Vortex 190ZK-53 Aluminum Rear Sprocket 53 Tooth

The Vortex 190ZK-53 is a 53-tooth aluminum rear sprocket engineered for performance motorcycle applications. Vortex Racing is a trusted name in the motorsports industry, producing precision-machined drivetrain components used by professional racers and serious enthusiasts worldwide.

This sprocket is manufactured from high-grade 7075 aluminum alloy, delivering an optimal balance of lightweight performance and durability. The precision CNC-machined teeth and carrier provide consistent chain engagement and smooth power transfer from the engine to the rear wheel.

Key Features:

• 53 Tooth count for tuned acceleration and gear ratio customization
• 7075 aluminum alloy construction for strength-to-weight advantage over steel
• CNC-machined for precise tolerances and consistent chain engagement
• Hard anodized finish for corrosion resistance and extended service life
• Direct OEM-style fitment for easy installation
• Compatible with standard 520 chain pitch (verify chain pitch for your specific application)

The 190ZK carrier designation identifies the specific bolt pattern and hub configuration. Upgrading to a higher tooth-count rear sprocket like the 53T increases acceleration and low-end torque at the expense of top speed — a popular choice for track days, motocross, and sport riding. Vortex sprockets are proudly made in the USA.
