The 1930 Norton model range introduced two new OHC engines, with the 500 at 79 x 100mm bore and stroke and a 350 Junior version at 71 x 88 mm. They were designated the CS1 and CJ. Using the old ‘three stay’ frame and three speed Sturmey Archer gearbox the new models were yet to be fully ‘tweaked’ and their victories that season were few and far between. By 1931 Norton had ironed out the problems of the previous year and the ‘Cammy’ Nortons swept the board, with Tim Hunt taking the first ever ‘double’ at the TT races with a first in both the Senior and Junior races. With riders of the calibre of Hunt, Stanley Woods, Jimmie Simpson and Jimmie Guthrie, the Norton race machines won practically every TT and continental race during the early 1930s. And when the likes of ‘Crasher’ White, Freddie Frith and Harold Daniells joined the team, Norton continued to dominate the world of motorcycle racing during the decade. In 1932, the 500cc International, as it was now called, was given the Model number ‘30’ and the 350 junior was designated the Model 40. In keeping with Norton’s dictum of “we only race standard products”, the machines available to the public were very similar to the works machines and many ‘privateers’ enjoyed racing their ‘Inters’ at numerous race meetings all over the world.
