RK 428HSB-108-CL — Reinforced 428H transmission chain, designed for intensive use in enduro and motocross. This "Heavy Duty" non O-ring chain combines alloy carbon steel construction, heat treatment, and shot peening of all components for enhanced mechanical strength on demanding terrains. Pre-tensioned and pre-stretched in the factory, it limits initial elongation and facilitates the tuning of the transmission.
Designed to withstand the stresses of the track — traction, impacts, jumps, and torque changes — this RK chain offers excellent value for money for riders looking for a robust and low-maintenance solution. Perfect for reassembling a transmission before a muddy outing or for replacing a worn chain on an off-road motorcycle.
