What’s No.1 ?

1.Chain Performance

Strong but Light - DID chain provide superior performance under any condition of usage. The chain performance is made from DID’s original chain processing technology and surface treatment methods of steel products.
Basically chain is likely to be made thicker and heavier for its longer life under the harsh condition of usage. However DID engineering philosophy stands on opposite sides. That is, DID think the nature of chain is strong but light.
As one of the most important part of driving unit, chain assumes a large role of transmission of power while keeping a harmony of all the mechanism. For adhering to the role, it’s necessary to seek stronger but lighter chain and eliminate the obstructive factor of heaviness. This attitude is very essence of DID engineering philosophy and it can be true to improve DID’s surface treatment technology which is superior in anti-wearing performance. DID’s strong but light chains are in the top level for anti-wearing performance, low fuel consumption, comfortable riding and so on.
