RK Excel – Since 1953
RK Excel originally began life as a company called Takasago Tekko K.K. back in
1930. Instead of manufacturing chain and rims, which wouldn’t be developed until
1953, Takasago produced a variety of aircraft components. After WWII, the
factory changed its name to Kusatsu and embarked on a new direction of
manufacturing bicycle components. This venture proved to be successful and in
1947 the bicycle chain department was established in the Shimura Factory.
In 1951 the chain department was separated from Takasago Tekko and Takasago
Chain Co. was established. In this year the company also began production of the
bicycle chains with the TCC mark. 1953 was the birth of RK motorcycle chains. In
1975 RK began experimenting with O-ring technology. RK’s efforts paid off and in
1982 chains with O-rings were in use on large to mid-sized motorcycles.
Excel Rims began to take form in 1952 when the Kusatsu factory began
manufacturing rims for two wheeled vehicles. The rim department of Kusatsu
separated, creating a new company Takasago Manufacturing. In 1956 the company
ceased the production of bicycle rims and concentrated on the development of
rims for motorcycles. In 1958 the Excel motorcycle rim program was launched.
In 1991 RK and Excel merged into a new company under the name RK Excel Co Ltd.
Today RK Excel makes some of the strongest parts in the motorcycle industry.
