RK Chain Quick Acceleration and Sprocket Kit

The RK Chain Quick Acceleration Chain and Sprocket Kit is a matched motorcycle chain and sprocket kit (also called a drive kit or final drive kit). It is built to improve acceleration and throttle response. The kits convert a heavier 530 or 525 drivetrain to a lightweight 520 chain and sprocket setup. This reduces rotating mass and gives crisper throttle response.

Key Features:

• 520 pitch racing-style chain: RK's premium sealed chain (XW-ring, RX-ring or O-ring depending on the kit) is cut to length for each application.
• Matched sprockets: The front and rear sprockets are precision matched to the chain for balanced performance and durability.
• Steel front sprocket: The front sprocket is hardened steel.
• Rear sprocket construction: Depending on the kit, the rear sprocket is lightweight 7075-T6 aluminum or induction-hardened high-carbon steel.
• Gearing for quick acceleration: Gearing is tuned for faster acceleration. Top speed may be slightly lower.
• Bike-specific kits: Each kit is tailored to a specific motorcycle application.

RK Chain is a long-established maker of motorcycle drive chains. This kit lets you replace the chain and both sprockets in one step with components designed to work together. It is a good upgrade for street and sport riding.
