RK Chains & Sprockets

RK Chains & Sprockets

For more than 60 years, RK Excel Co. and its predecessors have produced industry-leading drive chains for motorcycles and ATVs. Though the Japan-based company has merged and changed names several times, their commitment to premium, innovative chains has never wavered. Chain-drive riders know the sinking feeling when a chain falls off or breaks, leaving them stranded mid-ride or out of the big race. RK drive chains have carried Motocross, MotoGP, ASRA and many other powersport racers to championships around the globe, and Dennis Kirk carries a wide selection of chains that utilize the same technology for your machine.

RK’s reputation for quality drive chains has led to partnerships with Yamaha, Kawasaki, Suzuki and other manufacturers, with RK motorcycle chains now included as OEM parts on many dirt bike and sport bike models. As such, the chains we sell can often be used as direct factory replacements. RK standard drive chains outperform the heavy-duty chains made by many competitors, thanks to precise two-point riveting and curled bushings for tensile strength of more than 4,000 pounds. For a more economical solution with less powerful bikes, the RKM series of drive chains meets all of RK’s standard specifications.

Riders looking for a little more should turn to RK Max-X and Max-O drive chains. Premium Max-X series chains use sealed RX rings and four-point riveting for strength and durability even on the most powerful bikes. RK Max-O chains are designed with O-rings that fill the space between the chain and the link plates. This feature improves lubrication while blocking out dirt and debris for better performance and reduced wear. If your sprocket teeth need to be replaced as well, you can order RK chain and sprocket kits in both standard and racing models.

All RK chains are pre-stressed and pre-stretched for great performance right out of the box with minimal adjustments needed. Dennis Kirk also carries connecting links, press-fit tools and other accessories for chain installation and use.
