RK Chain

Looking for a chain that lasts for many miles and tough riding? RK manufactures drive chains for motorcycles, from small motocross and enduro bikes to big road machines. Here you’ll find O-ring and X-ring chains, off-road chains and connecting links, so you can choose the chain that suits your bike and your riding.

Japanese chain maker focused on motorcycles

RK is a Japanese manufacturer specialising in chains, and the name is well known both on the road and in motorsport such as motocross and road racing. The chain is one of the hardest-working parts on a motorcycle: it has to transfer the engine’s power to the rear wheel, withstand dirt, water and heat, and wear as little as possible. That is why RK focuses on durable materials, precise manufacturing and seals that keep the grease inside the links.

RK Chain’s key products

The core of the range is sealed chains with O-rings or X-rings, where rubber rings keep grease in the links and dirt out. This gives a longer service life and less maintenance, making them a popular choice for street and touring bikes. For motocross and enduro there are lighter chains, where low weight and low friction matter most. The chains come in different pitch sizes, such as 520, 525 and 530, and in several lengths and colours. Remember a suitable connecting link with rivet or clip lock, and ideally replace the sprockets at the same time. See each product for pitch and number of links.

Frequently asked questions

What is the difference between an O-ring and an X-ring chain?

Both types have seals between the links that keep the grease in. An X-ring has a different cross-section that gives less friction and often a longer service life. The choice depends on your bike, your riding and your budget.

Should I replace the sprockets when I replace the chain?

It is usually recommended. A new chain on worn sprockets wears faster, so chain and sprockets are typically replaced as a set. Check pitch and number of links before ordering.
