Strange how from an innocent question on engine capacity and type model name, now Austrians are weird?
This is a model number and it belongs to the Duke/RC bikes bearing a 373 cubic centimetres (not cubic inches) engine.
My first car was a 1968 Triumph Herald 1200
l later discovered l had been short changed in the engine department and it was actually 1147cc
However it burnt so much oil, that l imagine the engine was actually nearer 1200cc
l changed it for a 1971 Triumph Vitesse (basically the same car with a bigger engine) and at 1998cc it was actually only 2cc below the "2.0 litre" badges on the front wings.
