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 comes with an old-style buff logbook (issued 1946) recording matching frame, engine and registration numbers. A letter on file shows that the Norton has belonged to the late owner since at least 1995. It should be noted, the Vehicle Registration Number 'MP 2645' has lapsed from the HPI/DVLA database. Accordingly, prospective bidders must satisfy themselves as to the validity of the VRN prior to bidding. This motorcycle's condition, completeness, and correctness is not known and thus it is sold strictly as viewed.
