The RK M420H heavy-duty motorcycle chain is an economical, dependable replacement for motorcycles that were not originally equipped with an O-ring chain. Designed for applications using a 420 chain size, this 132-link chain provides reliable power transfer for compatible street, off-road, commuter, and recreational motorcycles.
Manufactured by RK, the M420H combines durable construction with practical serviceability. The included clip connecting link simplifies installation and makes this chain a convenient choice for maintenance, replacement, or drivetrain service. Always verify the motorcycle manufacturer’s recommended chain size, length, gearing, and connecting-link style before installation.
For fitment, use the RK M420H-132 manufacturer part number and confirm compatibility with the specific motorcycle model. This chain is intended for motorcycles that use a standard non-O-ring 420 chain configuration and may require adjustment or cutting depending on the original equipment chain length and sprocket setup. Proper lubrication, alignment, and tension adjustment are essential for maximizing chain life and maintaining smooth operation.
