Armstrong CCM


CCM Motorcycles was a British motorcycle manufacturer, located in Bolton, England. Alan Clews formed CCM (Clews Competition Motorcycles) in 1971 from what was left of BSA's off-road department and bought spares to produce his own motorcycles. This was a successful business and the Bolton factory was established. As you can see the early trials model was powered by the BSA engine in1978


In 1981 Armstrong bought a majority share and Clews designed a road race competition motorcycle. For most of the 1980s Armstrong-CCM produced about 3,500 motocross and trail bikes. The first Hiro powered trials models branded Armstrong CCM. The CMT 310 produced from October 1981 to March 1982 and later just Armstrong produced from April 1982 to March 1983. In total around 300 where made.                                                            


They acquired the rights to the Rotax engine enduro motorcycle SWM XN Tornado from the Italian owners and developed the Armstrong MT500 military motorcycle used by the British Army in the Falklands War. As you will see they started to produce Rotax powered trials bikes after SWM had folded in the mid 1980's


In 1983, the Canadian company Bombardier Recreational Products licensed the brand and outsourced development and production of the Can-Am motorcycles to Armstrong-CCM, who produced Can-Ams until closure in 1987, when Armstrong sold the military motorcycle business to Harley Davidson and CCM back to Clews, who continue to produce motorcycles as of 2010.
