Vortex Racing is a leading manufacturer of precision-machined sprockets trusted by racers and street riders worldwide for their exceptional strength-to-weight ratio and dimensional accuracy.

Key Features:

• 55-tooth rear sprocket for optimized acceleration and gear ratio tuning
• Precision CNC-machined from high-grade aluminum alloy for reduced unsprung weight
• Hard anodized finish for corrosion resistance and long service life
• Manufactured to OEM dimensions for direct fit installation
• Compatible with standard 520 chain pitch (verify chain pitch for your application)

Upgrading to a Vortex rear sprocket allows riders to fine-tune their motorcycle's final drive ratio for improved low-end torque, faster acceleration, or higher top-speed potential depending on the tooth count selected. The lightweight aluminum construction helps reduce rotational mass for improved throttle response.
