Description
A quality front sprocket is fundamental to reliable power delivery and chain longevity. JT’s rubber-cushioned design absorbs chain impact that would otherwise cause premature wear and noise, while the heat-treated C45 steel construction maintains strength under sustained load. This is the same OEM-proven technology trusted by major Japanese motorcycle manufacturers—proven durability without compromise.
