Rk MXU Series 120 links 520 Universal ChainRef : RK00195A / 12220194

MXU Series Transmission Chain by RK (manufacturer reference GB520MXU-120-CL): an O-ring chain designed for reliable transmission on both road and off-road. Its 520 profile is suitable for small to medium engines and targets roadster, enduro, and motocross enthusiasts looking for a robust chain with a refined visual finish (gold finish).

Made from steel with O-ring seals, this chain minimizes lubricant loss between the roller and link, which helps reduce premature wear of moving parts and preserve the transmission. Its construction allows for consistent power transmission between the sprocket and the crown, even in mixed use.
