AMC introduced their response to the Speed twin in 1949 when they unveiled the Matchless G9 and AJS model 20 twins. The two new machines were notable in that they utilised a pivoted fork frame from the outset and were finished to the usual exceptional AMC standards. By 1956 it was apparent that a larger displacement model was needed to compete against the 650cc twins offered by Triumph and BSA, particularly in the States. The result was the announcement of the G11 and Model 30 twins displacing 593cc. These were joined by a pair of sports models in 1957 coded the CS and CSR, the former being a "scrambler" aimed at the American West Coast and the latter a super sports roadster. As the fifties drew to a close AMC recognised the requirement for a full 650cc to be able to compete on equal terms with their major rivals prompting the introduction of the Model 31 and G12 twins displacing 646cc in 1958. Like their predecessors, the G11/ Model 30, the new models were offered in four versions, the CS and CSR sportsters and the more touring orientated standard and de luxe models, which differed only in the finish and the use of an alternator on the standard machine. The range continued in this form until 1961 when the CS variant was dropped with further rationalisation taking place for the 1962 season when the de luxe version left the catalogue and the CSR adopted the road frame instead of the scrambles chassis.
This example of the Matchless G12 CSR variant is offered in good condition with black paintwork and has formed part of a significant private collection in recent years.
