Lot Details
1959 Matchless 498cc G9
Registration no. 923 GEH
Frame no. A67262
Engine no. 59/G9/51956
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. Like those of its major rivals, AMC's original 500cc offering would remain the sweetest of the many larger alternatives. 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.

'923 GEH' was in running order when purchased by its late owner at Bonhams' Harrogate Sale in November 2003 (Lot 422). The owner stripped the motorcycle for restoration and some work was carried out but the project was never completed. The fuel tank, mudguards, oil tank cover and toolbox have been repainted and the shock absorbers replaced with new Hagon units. It is not known how much work has been done to the rest of the motorcycle, which will require careful checking as part of the completion process. A workshop manual (on CD) comes with the machine, which is offered with purchase invoice (2003), old-style continuation logbook (1970), two expired MoT certificates and Swansea V5C registration document.
