Engineered and manufactured in Japan, the DID 420D is a high quality chain built for light, high powered (up to 85cc petrol engine) bikes. It is a great improvement over the factory installed chain and a perfect fit for standard powered or bikes up to 10kW.
It features a tensile strenght of 1 800kg (3 970lbs) all the while offering an extended lifespan. This chain is a standard, non o-ring chain, allowing for the lowest friction coeficient.
As a matter of fact, o-rings reduce chain maintenance at the detriment of performance, especially on our light electric bikes, as they rob horsepower and precious battery-life.
