1962 AJS 646cc Model 31
Registration no. 4379 MW
Frame no. A80632
Engine no. 62/31 X7037
When announced in 1948, the AJS Model 20 and equivalent Matchless G9, while following the established pattern of British parallel twins, were unusual in having an engine with a third, central, crankshaft main bearing. The new 498cc power unit was housed in the sprung frame recently introduced to the heavyweight singles line-up. Progressively developed, the motor underwent a number of capacity increases, finally arriving at 646cc in the autumn of 1958 with the launch of the AJS Model 31 and Matchless G12. Well-finished, stylish and deservedly popular despite lacking the performance image of certain rivals, the AMC twins were much missed after their demise in 1966.
Last taxed for the road in 1976, this matching numbers, Wiltshire registered AJS Model 31 is offered with two expired MoT certificates (most recent 1978), old/current Swansea V5/V5C documents and old-style continuation logbook (issued 1976) listing the vendor's father as the second of only two owners recorded.
