1955 Matchless 498cc Model G45

Based on the Model G9 Super Clubman vertical twin, a one-off racing twin was produced in time for the 1951 Manx Grand Prix, on which Robin Sherry came 4th at 83.71mph.

For 1952, the first Model G45 came into being, the engine still recognisably G9 based but housed in a 7R AJS based frame etc. This time Derek Farrant won the MGP at 88.65mph. Thus encouraged, AMC Ltd, put the G45 into production and itwas shown at Earls Court in November.

As a production racer it performed well and no less than 17 of them lined up on the Glencrutchery Road for the start of the 1955 Senior TT, best placing being a very creditable 6th, by Derek Ennett at 92.54mph.
