RK 428HSB-100-CL Transmission Chain – 428H Heavy Duty (non-O)
Designed for intensive use, this RK 428H Heavy Duty chain without O-rings offers a cost-effective alternative to standard chains while providing increased strength. The links are made of carbon alloy steel, all heat-treated and shot-peened to enhance mechanical performance. Pre-tensioned and pre-stretched in the factory, the chain limits initial elongation and facilitates the start-up on your transmission.
Versatile, it adapts to trails, roadsters, touring bikes, and more off-road or racing-oriented machines when seeking robustness and budget control. To maintain optimal transmission, regular lubrication, tension checks, and inspection of the links after intensive use are recommended.
