1960 AJS 646cc Model 31 De Luxe
Frame no. A77046
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. Previously registered in the UK, this particular AJS Model 31 De Luxe was purchased at the Beaulieu Autojumble in 2006 and used rarely before being restored to its current concours condition. Completed in February 2012, the work was carried out by Kickstart Classic Motorcycles (Neil Fulcher) of Frieston, Lincolnshire, whose detailed invoice for £6,523 is on file. The machine has covered only 70 miles since the rebuild and has been kept in dry storage and maintained in working order. Offered with Republic of Ireland registration documents.
