RK Chain – Having been producing motorcycle chains since 1953, has been at the forefront of motorcycle drive chain technology, developing the sealed ring chain in the mid 1970’s.

RK’s sealed ring drive chain was thrown in to the spotlight during a 24 hour endurance race, in which teams typically changed the drive chain 3 times during the race. But when a team using the newly developed sealed ring chain from RK went on to win with a chain that lasted the entire race, a new standard had been set.

This was just the beginning, and now has more than 40 years of experience researching, testing and developing chains for high performance motorcycles. RK Takasago chain, the name that has long been synonymous with quality.
