Description

Chain and sprocket wear is one of the most common wear items on track-focused and high-mileage YZF-R6 machines, directly impacting acceleration, top-end performance, and overall drivetrain reliability. This RK OEM replacement kit restores your R6 to factory specifications using premium case-hardened steel construction, ensuring consistent power delivery without the guesswork of aftermarket gearing changes. If your chain shows visible stretch or your sprockets display hooked teeth, this kit is essential maintenance that will eliminate power loss and restore predictable handling characteristics.

Helps keep cool, works great!
