• Offered for restoration
• Believed to have been ridden by Douglas Lamb
• Original Moore-designed CS1
Like the majority of their contemporaries, Norton relied on the sidevalve engine until the introduction of its first overhead-valve design in 1922, and the resulting Norton Model 18 was a big success on the road. On the racetrack however, Velocette had shown the way forward when its overhead-camshaft KTT romped away from the field in the 1926 Junior TT, and Norton responded with its own similar engine the following year. Designed by Walter Moore, the Norton motor retained the firm's traditional 79x100mm bore and stroke dimensions, employing bevel gears and a vertical shaft to drive the cams in KTT fashion. The cycle parts too were new: a cradle frame and saddle tank appearing for the first time on the works CS1 racer, which scored a debut win in the 1927 Isle of Man Senior TT with Alec Bennett riding. The production version of the new CS1 duly appeared at the Motor Cycle Show later that same year.
Towards the end of the 1930 season a new overhead-camshaft engine began to be seen in the works Nortons. Designed by Arthur Carroll, this replaced the original 'cammy' motor that had been drawn up by Walter Moore, recently departed for NSU, and first appeared in production Nortons made for the 1931 model year. The existing CS1 (490cc) and CJ1 (348cc) model designations were carried over from the Moore era, and the pair continued as Bracebridge Street's top-of-the-range sports roadsters until 1932 when the arrival of the competition-orientated International models saw them re-branded as refined sports-tourers. Today the original Moore-designed CS1 is one of the most sought after of all Norton motorcycles.
Offered for restoration, this incomplete CS1 is believed to have been ridden by Douglas Lamb, who competed in the Isle of Man TT on three occasions: the Senior race in 1928 and 1929, and the Junior in 1929, Norton-mounted in each case. He died in June 1929 following a fatal crash in the Senior race (see VMCC correspondence, photographs, and photocopied press cuttings on file). This motorcycle's condition, completeness, and correctness is not known and thus it is sold strictly as viewed. It should be noted that the frame number appears to have been stamped twice in different fonts.
