The ‘’’BSA Spitfire’’’ was a British motorcycle launched in 1966. One of the first BSA’s to have 12-volt electrics, the Spitfire was also one of the first ‘’street racers’’ with two large-bore Amal GP carburettors, complete with velocity stacks[1].

The Spitfire had a new twin-downtube steel frame and new Girling shocks. A 190mm front drum brake improved braking and and lightweight alloy rims reduced the weight to 174kg[2].


The 1968 MkIV Spitfire was the last made. Amal’s new Concentric carburettors were combined with twin-leading-shoe front brakes and independently adjustable Lucas ignition points for easier starting. Engine power output was increased to 53 bhp.[3]
