Reinforced RK 428H transmission chain, designed for enduro and motocross riders who put their transmission to the test on demanding terrain. This non-O (without O-rings) chain features a robust construction made from carbon alloy steel: all components have undergone heat treatment and shot peening to enhance fatigue and wear resistance. Pre-tensioned and pre-stretched in the factory, it limits initial elongation and reduces the need for frequent adjustments after installation.
Ideal for those seeking a robust, reliable, and economical chain for off-road use. Remember to regularly check the tension and lubrication according to your practice to maximise the lifespan of the transmission.
