All motorcycle chain regardless of brand is a consumable product; which means that it will not last forever and will eventually need to be replaced.  RK Chain suggests that chains need to be replaced when it is worn or at best every 20,000 miles and every 3,000 miles for non-sealed chains if they are maintained correctly. You should also change both the front and rear sprocket whenever you replace the chain.

RK Chain recommends cleaning a sealed chain with only a mineral based O ring safe chain cleaner. Do not use kerosene, mineral spirts, diesel fuel, brake cleaner, motor oil or any caustic chemicals because that can damage the seals. RK recommends that you douse a rag with the mineral based O ring cleaner and wipe the dirt off the chain. Do not use a wire brush or hard bristle brush to clean a sealed chain. The wire or hard bristles can damage the seals reducing the life of the chain.

RK Chain recommends that after cleaning the chain and before lubrication, go for a short ride around the block to remove most of the chain cleaner and or water from the chain. RK recommends that you then follow up with a quality chain lubricant designed for sealed chains while the chain is still warm.

Cleaning a non sealed chain is the same as a sealed chain. RK Chain recommends cleaning a non-sealed chain with only a mineral based O ring safe chain cleaner. Do not use kerosene, diesel fuel, brake cleaner, motor oil or any caustic chemicals. RK recommends that you douse a rag with the mineral based O ring cleaner and wipe the dirt off the chain.

WE HIGHLY RECOMMEND USING A MOTORCYCLE O-RING CHAIN SPECIFIC CLEANER AND LUBE SUCH AS MOTOREX CHAIN CLEAN, AND ONE OF THE MOTOREX CHAIN LUBE FAMILY.
