D.I.D never compromises even for Mini bike racing chain. This youngest brother of the D.I.D MX racing chain line has the same solid bushing and SDH pin surface treatment for greatest performance. Future Champions ride with this chain.
The SDH pin treatment creates an extremely hard chromium carbide layer on the pin surface which increases chain life. At the same time the pins inner core remains soft to absorb the tremendous shock loads of triple jumps without breaking.
