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 Norton International is the street version of one of the best racers ever built, the Norton Manx, and shares the Manx’s handling qualities and gorgeous good looks.


In the 1920s, Norton hired Walter Moore to design an overhead-cam engine that was intended to power both a racer and a sport motorcycle. This 490cc engine was not quite perfect, and was redesigned in 1930 by Arthur Carroll. The Carroll engine became the famous name " International". Arthur Carroll had designed an overhead-camshaft engine for the works racers and although it retained the 79 mm × 100 mm bore and stroke of the Norton CS1, the Model 30 International was all new. The model International led to many successes and made the name of a legend living till today.


After the war, production of the International restarted. The suspension was upgraded to Norton Roadholder telescopic forks instead of girders. Close ratio gearboxes were supplied as standard from 1947, and the all alloy engine made a comeback in 1950. A new Featherbed frame was introduced in 1953. The production of the International ended in 1955.


The current owner purchased this matching numbers 1953 Norton Model 30 490 cc International more than 20 years ago from the UK and imported it to Austria. The machine has been restored in the UK to high standards, approximately in the '90-s. After restoration, the bike has seen only limited use since.


It is fitted with an all aluminium alloy overhead camshaft engine, 4 speed gearbox, Featherbed frame (which was new for model year 1953), Roadholder telescopic front forks and beautiful chrome plated petrol tank. Further components include Lucas electric lighting system and Smiths Chronometric speedometer. There is currently an Amal Concentric carburettor fitted for better performance, but the original Amal TT carburettor comes with the Norton as well.

This Norton Inter runs and rides fine, it is ready to be enjoyed. There are Austrian registration documents with this superb motorcycle.
