*The corresponding link is a link in case of mounting to a vehicle in a full normal. Please note that the number of the corresponding link might be different in case of changing the number of the sprocket or customization. *Please avoid from using it on public road because it is a product that is exclusively designed for competition. *With regards to the installation, please make sure to check it at the pro shop and etc. with qualified mechanics and skills along with changing the chain size on your own. *It requires special tool to ZJ: rivet type.
It is a race model that thoroughly sought zero friction
•Feature 1: Minimum/Lightweight, Friction/zero non-sealed chain It is also supported by many teams in the MotoGP World Championships and the All Japan Championships GP3 class. It is a small engine displacement class where slight resistance is the difference in the rank, and there is a difference in the growth of the vehicle speed at high speed.
•Feature 2: Special Pin Reinforced Processing "SDH" This treatment method forms a very hard chromium carbide film on the surface of the pin and disperses the carbide with high hardness inside. It suppresses wear on pins that cause chain elongation and exhibits high wear resistance even in harsh environments. It is possible to reduce the weight by about 20-25% including the sprocket by converting from 420 to 415.
•Feature 3: The life is increased by adopting cold forged solid bush It is a high stiffness bushing with a smooth surface that is seamless and excellent roundness. With the optimization of the contact surface between the pin and the bush and the specially developed special grease, the wear of the pin, which is the cause of chain elongation, is suppressed, and the wear life is improved by 1.2 to 4 times over the conventional type.
I used to chain it very well I used to race cars.
It's a very good song, but it's good.
Very little tight really tight.
