Manufacturer's ref: 428HSB-146-CL — RK 428HSB transmission chain, Heavy Duty non-O version, specially designed for off-road use (enduro / motocross).
This o-ring-less chain offers a robust and economical solution for riders who tackle demanding terrain. Made from carbon alloy steel, each component has undergone heat treatment and shot peening to enhance fatigue resistance. The chain is pre-tensioned and pre-stretched to limit elongation during break-in and ensure more stable tension from installation.
Ideal for riders seeking a durable transmission to tackle mud, stones, and harsh conditions, the RK 428HSB-146-CL chain prioritises robustness and value for money without the bulk of o-rings, facilitating maintenance and the frequent cleaning typical of off-road riding.
