“D.I.D Bush Chains: Over 90 Years of Protecting the Heart of the Engine”

Inside an engine lies one of the harshest environments — high temperatures, intense vibration, and extreme rotational speeds.
In this unforgiving space, one component must operate with precision, silence, and reliability, millions of times. That’s the role of the D.I.D Bush Chain.

D.I.D (Daido Kogyo) is a trusted Japanese brand with over 90 years of experience in manufacturing high-performance engine chains.
What sets it apart is the solid bush structure — crafted from solid steel rather than rolled material — providing superior wear resistance, minimal elongation, and excellent oil retention.

The result? Outstanding durability, long-term timing accuracy, and reduced noise.
This is why leading motorcycle manufacturers around the world continue to rely on D.I.D.
