DID is a Japanese manufacturer of high-performance transmission components and is internationally known for its quality chains and chain sets. “ERV” chains consist of X-ring links and are directly derived from MX competition chains.

The latter are intended for enduro such as rally raid and are reinforced for a longer life. They optimize the transmission of power to the rear wheel and offer the pilot more feeling when accelerating.

These chains are SDH treated, which gives them antioxidant properties, reduces friction and provides better resistance to external agents such as mud, sand, etc.
