RK 428HSB-120-CL — Heavy duty transmission chain designed for off-road use. Intended for enduro and motocross riders seeking a robust and economical solution, this non-O ring chain features a carbon alloy steel construction to withstand the demands of muddy and stony terrains. Supplied with a clip connection link for easy and quick installation, it is a reliable option for motorcycles not originally equipped with O-rings.
Ideal for primary transmission on small displacement engines, the 428HSB offers a link geometry suitable for standard sprockets and crowns. Its natural finish reduces the risk of sticking in mud and facilitates maintenance on the field. Installation and adjustment require standard tools (axle puller, tensioner) and regular tension checks are recommended to ensure safe and consistent operation.
