◆A race model that thoroughly pursues zero friction *Specially for small displacement ●Non-seal chain aiming for zero friction with the smallest and lightest weight Supported by many teams in the MotoGP World Championship and the GP3 class of the All Japan Championship . In the small displacement class, where a slight amount of resistance can make a difference in ranking, there is a difference in the increase in vehicle speed at high speeds. *This product is designed for competition use only, so please refrain from using it on public roads. ●Special pin strengthening process "SDH" This is a processing method that forms an extremely hard chromium carbide film on the surface of the pin and disperses the highly hard carbide inside. It suppresses pin wear that causes chain elongation, and exhibits high wear resistance even in harsh environments. ●Lightweight By converting from 420 to 415, it is possible to reduce the weight by about 20~25% including the sprocket. (Please be sure to change the chain size at your own discretion, and for installation, please check with a technically competent bike shop etc.) ●Uses cold forged solid bushings for long lifespan.No seams. A highly rigid bushing with a smooth surface and excellent roundness. By optimizing the contact surface between pins and bushes and using a uniquely developed special grease, pin wear, which is the cause of chain elongation, is suppressed, and wear life is increased by 1.2 to 4 times compared to conventional types. ★D.I.D chain joint symbol explanation The joint strength is expressed as RJ>FJ>ZJ. For sealed chains and medium displacement vehicles and above, we recommend using a ZJ (caulking) joint.・RJ (clip type): Can be used with pliers or pliers.・FJ (light press-fit clip type).Use "Kashimaru-kun" when press-fitting the plate. After press-fitting, work can be done with pliers.・ZJ (caulking type): A type that uses "Kashimaru-kun" for plate press-fitting and pin caulking. Precautions for use *This product is designed for competition use only, so please refrain from using it on public roads.
