Product Info

  • Universal 428 Chain

NOTE: RK rates it to 15 hp, for bikes that came with a non-sealed chain

RK's non-sealed heavy duty chains now use four side, or quad, rivet staked pins, which RK says are stronger and more stabilized, raising stress resistance under high loads and putting horsepower to the ground more efficiently. The bushings are solid and cold forged, a process that strengthens the metal for a stronger, more rigid chain, and RK adds a specially formulated coating.

RK says those three changes together show a 40% increase in chain life. The chain is not endless, so it goes on with its included clip connecting link, and RK warns never to use two connecting links on one chain. RK also recommends new sprockets with every new chain, since damaged, worn or misaligned sprockets shorten chain life.

RK rates the M428H at 5,400 lbs tensile strength with a maximum chain width of 20.3 mm and a maximum of 15 HP, and it weighs 1.01 kg per 100 links. RK recommends installation by a qualified mechanic with the proper tools.
