Metmachex Engineering was registered in 1978, our trading name being derived from the words Metal Machining Experts. The main source of income at first was sub-contract work, interspersed with design and machinery repairs.

Our swinging arms, which have become known worldwide throughout the motorbike industry, were first initiated by a customer who asked for his LC350 swinging arm to be repaired. The repair was to be found to be too costly and Metmachex designed a new one made out of aluminium. Soon after, more orders came in for us to design and manufacture a mirror polished aluminium swinging arm for all kinds of bikes.

In 1994 we found it necessary to move to a new and bigger 5000 sq. ft. factory unit. Since then we have installed new computerised machinery in order to produce our latest concepts in swinging arm design
