The 850 cc MK3 Commando was launched in 1975 with an improved specification – electric starter, isolastic head steady for improved vibration absorption, left side gear change and right side foot brake to comply with United States vehicle regulations, and a rear disc brake. The range of models was reduced to just two machines, the ‘Mk.3 Interstate’ and the ‘Roadster’. The specification remained unchanged until October 1977 when the last machines were made, although few Roadsters were made in the end due to the higher cash sales value of the Interstate.
