The RK 428HSB-140-CL chain is a reinforced transmission chain designed for the demands of off-road riding (enduro, motocross). This heavy-duty chain without O-rings offers an economical solution for riders who put their chain to the test on abrasive terrains and in racing or intensive training conditions.
Material: carbon alloy steel, all components heat-treated and shot-peened for better durability.
Pre-tensioned / pre-stretched: limits initial elongation and stabilises performance in service.
Links: 140 links (quick clip connector included).
Colour: natural.
Compatibility displacement: up to 125–200 cc depending on application.
Weight: 1.01 kg for 100 links (manufacturer's reference).
Designed for enduro/motocross use, this chain prioritises strength and longevity while remaining easy to maintain (no O-rings). Ideal for replacing an original chain on a light to medium displacement motorcycle or for preparing a transmission that can withstand the stresses of the terrain. Supplied with a quick clip connector for fast mounting on the sprocket and the crown.
