Vortex 641AS-48 Aluminum Rear Sprocket Sprockets - 48-Tooth

The Vortex 641AS-48 is a high-performance aluminum rear sprocket designed for sport bikes and performance motorcycles. This 48-tooth sprocket is precision-engineered to deliver optimal power transfer while reducing rotational mass for improved acceleration and handling.

Key Features:

• 48-tooth configuration for customized gearing ratios
• Constructed from aerospace-grade aluminum alloy for superior strength-to-weight ratio
• Precision CNC-machined to exact tolerances for perfect chain alignment
• Hard-anodized finish provides corrosion resistance and extended wear life
• Lightweight design reduces unsprung weight and improves throttle response
• Compatible with 530-pitch chains

Vortex sprockets are manufactured in the USA and undergo rigorous quality control testing to ensure racing-grade performance. The reduced rotational mass compared to steel sprockets allows for quicker acceleration and improved handling characteristics, making this an excellent choice for track day enthusiasts and street riders seeking enhanced performance.
