Vortex CK6307 HFRS Hyper Fast Chain and Sprocket Kit - 520

The Vortex CK6307 is a complete HFRS (Hyper Fast) 520 conversion chain and sprocket kit designed to improve acceleration and reduce rotating mass on Suzuki GSX-R motorcycles. This performance-oriented kit converts the stock chain pitch to a lighter 520 configuration while adjusting the gearing ratio with one tooth down in front and two teeth up in the rear for enhanced low-end torque and quicker acceleration.

Key Features:

• HFRS configuration with 16-tooth front and 44-tooth rear steel sprockets
• 520RX3 chain with 110 links featuring tri-glide seal design
• Laser-cut steel rear sprocket with electro-plated black finish for durability
• High carbon steel, nickel-plated front sprocket with drilled lightening holes
• RX3 chain provides up to 10 times the wear life of standard O-ring chains
• Pre-sized chain requires no cutting for installation
• Includes rivet-type master link
• Made in Japan to highest quality specifications

This 520 conversion kit offers weight savings compared to OEM components while maintaining excellent durability with the steel sprocket construction. The modified gearing ratio delivers improved off-the-line performance and faster acceleration through the gears, making it an ideal upgrade for street and track riders seeking enhanced performance.
