Announced in 1948 and progressively developed thereafter, AMC's twins had already undergone a number of capacity increases before finally arriving at 646cc in the autumn of 1958 with the launch of the AJS Model 31 and Matchless G12. The new range-topping super sports models were typed 'CSR', a designation AMC had first used on the superseded 600cc versions. Motor Cycling achieved a top speed of 108.5mph with 'their' G12CSR while fuel consumption averaged 51mpg over the course of the 500-mile test.
Purchased by the late owner in December 2007, this partially dismantled G12 CSR is offered for restoration and sold strictly as viewed. The detached parts are contained within a number of boxes. Accompanying paperwork consists of sundry invoices and correspondence, some items of photocopied AMC-related literature, a parts list, old-style continuation logbook (issued 1969) and V5/V5C registration documents. It should be noted that the engine has been replaced (number not changed on V5C). No reserve.
