Lot 285: 1950 Norton International 490cc Model 30

Collectors' Motorcycles, Bonhams (19 October 2008)

One of the most charismatic model names in motorcycling history, ‘International’ was first used by Norton for its top-of-the-range sports roadster in 1932. The Inter’s Arthur Carroll-designed overhead-camshaft engine had been developed in the works racers for the preceding two years, and although it retained the classic 79x100mm bore/stroke dimensions and shaft-and-bevels cam drive of the existing CS1, was entirely new. Based on the works bikes and intended for racing, the International could nevertheless be ordered with refinements such as lights and a kickstart-equipped gearbox. By the time production halted in 1939 it was being built with a four-speed foot-change ’box and plunger rear suspension (the ‘Garden Gate’ frame), reappearing after the war in similar guise save for the adoption of the hydraulically-damped Roadholder front fork, which replaced the pre-war girder. The vendor advises us that this International was supplied new to special order by the factory fitted with an all-alloy engine and Manx cam box/internals for clubman’s racing in the USA, from whence it was re-imported in 2005. The machine has since been totally restored to original specification by the current owner, a dedicated Norton enthusiast, and completed only this year. We understand that a Swansea V5C registration document has been applied for, though the DVLA has indicated that it will not be issued until the end of October. Offered with restoration invoices.
