Lot 183: 1957 AJS 593cc Model 30

Associated Motor Cycles’ first stretch of its 500cc parallel twin took it out to 550cc in 1954, but this US-only variant would prove relatively short-lived and was swiftly superseded by an even bigger version. Introduced for 1956, the AJS Model 30 and equivalent Matchless G11 boasted an engine of 593cc, which went into the newly introduced cycle parts shared with the heavyweight singles range. Along with the new frame came a restyled oil tank and toolbox, full-width front brake and longer seat, while the excellent AMC gearbox - also fitted to Nortons, including the Manx - was phased in during the year. Offered for restoration, this Model 30 is accompanied by Swansea V5.
