Norton Commando models used "Isolastic" engine mounts (rubber mounted) and had 745 cc ("750") engines up to 1973 when the 828 cc ("850") engine came into use.

Years
Notes
Commando Fastback
1967–1973
Just called "Norton Commando" until 1969
Commando Roadster
1970–1975
750cc 1970-73, 850cc 1973–1975. Targeted for the American market
Came with "2S" cam, shaved head to increase the compression, and was made in both Roadster and Interstate form. Early on there were engine failures which quickly gave the Combat a bad name. Even though those problems were rectified, the press was so bad that the name was discontinued later in the year.[1]
Commando "Combat"
1973
Officially, there was no 1973 Combat, but the engine was still available. This is still confusing today as some parts manufacturers list a 73 Combat, meaning the high compression engine.[1]
