Designed to withstand the traction and abrasion encountered in competition, this chain is aimed at motocross and enduro riders who want a solid transmission without sacrificing weight. Before installation, check compatibility with your motorcycle (e.g., Honda CR 250 R ME03 1992–1993) and ensure proper tension/alignment adjustment to guarantee even wear of the links and sprocket.
