A racing model that thoroughly seeks zero friction.

■Feature 1: The smallest and lightest non-seal chain with zero friction
It is supported by many teams in the GP3 class of the MotoGP World Championship and the All Japan Championship.In the small displacement class, where a small amount of resistance makes a difference in the ranking, there is a difference in the increase in vehicle speed in the high speed range.

■Feature 2: Special pin strengthening process "SDH"
This is a treatment method to form a very hard chromium carbide film on the surface of the pin and to disperse hard carbides inside.The pin wear is reduced, which can cause chain elongation, and high wear resistance is achieved even in harsh environments.
By converting from 420 to 415, you can reduce the weight by 20-25% including the sprocket.

■Feature 3: Longer life by adopting cold forged solid bushes
This is a highly rigid bush with a smooth, seamless surface and excellent roundness.The contact surface between the pins and bushes has been optimized and a special grease has been developed to suppress pin wear, which is the cause of chain elongation, and the wear life has been increased by 1.2-4 times compared to the conventional type.
