RK Chain 428-140 - Natural

Features 4 side (Quad) rivet staked pins. When pins are quad riveted they are stronger and more stabilized; which results in increased stress resistance due to high engine loads and makes the transmission of horsepower to the ground more efficient.

Now includes solid bushings! RK’s solid bushings are constructed by a process called Cold Forging. The forging process strengthens the metal component of the bushing which results in a stronger more rigid chain.

As a result of the change to the 4 rivet staked pins, the addition of solid bushings and the application of RK’s new specially formulated coating; RK non-sealed chains now show a 40% increase in chain life!

RK non-sealed chains perfect for low displacement motorcycles that did not come from the factory with sealed chains. If the motorcycle came from the factory with a sealed chain, then RK recommends always replacing it with a sealed chain.

When choosing RK Non-Sealed Heavy Duty chains, please make sure the chain you choose has a suitable CC rating for the CC’s of your motorcycle.
