Key advantages you’ll notice on every ride

• Durable construction: high-strength alloy pins and rollers engineered for high-torque applications, ensuring reliable power delivery with minimal stretch over time.


• Corrosion resistance: sealed rings plus robust plates protect against corrosive road grime and weather exposure, extending chain life in wet climates.


• Improved riding feel: tighter tolerances and consistent pitch help deliver precise acceleration and throttle response, especially during spirited riding or track days.

Maintenance and fitment tips
