Vortex HFRS Chain and Sprocket Kit

The Vortex HFRS (Hyper Fast Steel) Chain and Sprocket Kit is a complete 520 conversion final drive kit for Kawasaki street motorcycles. It replaces the chain and both sprockets in one package, and the gearing change sharpens acceleration and throttle response. Riders may also know it as a chain and sprocket set, a drive chain kit or a final drive kit.

Key Features:

• Hyper Fast 520 conversion street kit with a laser-cut steel rear sprocket
• Gearing is one tooth down in the front and two teeth up in the rear for quicker acceleration
• Steel front sprocket with drilled lightening holes to reduce rotating mass
• Steel rear sprocket with a corrosion-resistant black finish and a tooth design made for good chain hold and release
• Hardened sprocket teeth are made to hold up over many miles
• Vortex 520 X-ring chain with sealing that reduces friction and helps retain lubrication
• Includes a rivet-type master link
• 520 chain setups are lighter than 525 or 530 setups

Each kit combines a front sprocket, a rear sprocket and a chain that are matched to work together. This gives you a durable, ready-to-install replacement for street and spirited riding. Specific tooth counts, chain length and chain type vary by part number.
