The Armstrong MT500 is a British military motorcycle made by Armstrong-CCM Motorcycles in Bolton, Lancashire, who acquired the rights to the Rotax engine enduro motorcycle SWM XN Tornado from the Italian owners and developed the MT500 for use by the British Army in the Falklands war.[1] Electric start models were built for the Canadian and Jordanian armed forces.[2]

In 1987, the design and production rights were sold to Harley-Davidson, who in 1993 released the MT350E. The MT Riders Club exists for owners of these bikes around the world.
