Like those of its major rivals, Associated Motor Cycles' parallel twin engine started life as a 500 before undergoing a number of capacity increases. Similarly, AMC's original 500cc offering would remain the sweetest of the many alternatives. Announced in 1948, the Matchless G9 and equivalent AJS Model 20, while following the established pattern of British parallel twins, were unusual in having a third, central, crankshaft main bearing. The new 498cc engine was housed in the sprung frame recently introduced on the heavyweight singles. Progressively developed, the motor underwent a number of capacity increases, finally arriving at 646cc in 1958 with the launch of the AJS Model 31 and Matchless G12. Production of the 500cc models ceased in 1961 and that of the 650s in 1966. Well-finished, stylish and deservedly popular, the AMC twins were much missed after their demise.
This restored example was purchased by the current vendor in a basket case condition with the intention of restoring it back to its former glory which was finally achieved this year when it was started up and ran to ensure everything worked. After this process, the vendor drained all of the fluids and has dry stored it since, therefore it will need careful recommissioning and running in before use. It should be noted that the engine has been uprated to 600cc (the V5C still records the capacity as 500cc). Documentation consists of a V5C, old style log book and dating certificate from the AJS/ Matchless Owners Club.
All lots are sold 'as is/ where is' and Bidders must satisfy themselves as to the provenance, condition, age, completeness and originality prior to bidding. Visit the Bonhams Motorcycles website for all pertinent auction information.
