This part being universal, it may require adaptations
MXU Series Transmission Chain (GB520MXU-112-CL) — RK offers an O-ring chain designed for off-road requirements: gold finish, 112 links, and compatibility with 125–500 cc motorcycles. Designed for motocross/enduro use and suitable for adapted roadsters, it focuses on durability and reduced maintenance to keep the transmission reliable on muddy tracks or rolling roads.
The chain is pre-tensioned and pre-stretched in the factory to promote even load distribution and reduce initial maintenance. The O-rings protect the rollers and pins from dust and mud, contributing to increased longevity and a smoother torque transmission. Ideal for demanding riders who want a robust part ready to tackle tough terrains without surprises.
