The original model was designated the 'Fastback' in March 1969 to differentiate it from the newly introduced 'S' and 'R' models. A modified frame was fitted to overcome the earlier breakages. A Mk2 Fastback was introduced in September 1970 with revised stands, chain guard, alloy levers with integrated switchgear and the 20M3S engine. A metal tank, 4.10 x 19 front tyre, upswept exhausts and reverse cone megaphone silencers were fitted on the 1971 MK3.

The ‘Combat engine’ engine was introduced in January 1972 in the Mk4 Fastback. The last of the fastbacks, the MkV, was produced from November 1972 to mid-1973 as a 1973 model and featured improved crank bearings and the standard grind camshaft. Compression was reduced to 9.4:1.
