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 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, forcing Norton to respond with its own similar engine the following year. Designed by Walter Moore, the Norton motor retained the firm's traditional 79x100mm bore/stroke dimensions, employing bevel gears and a vertical shaft to drive the overhead 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.

A 1928 model, this CS1 was delivered new to Victor Horsman's Liverpool dealership on 15th December 1927. Our vendor purchased the Norton from a UK auction in December 1993. At that time the machine carried the registration 'SV 4616', however the HPI / DVLA reports list the machine as having been 'Permanently Exported and the machine is now offered without documents, subject to the usual import channels. Accordingly, prospective purchasers must satisfy themselves with regard to this motorcycle's registration status prior to bidding and will be responsible for any post-purchase DVLA applications should they wish to attempt to retrieve the VRN.

The 1993 catalogue described the Norton as subject of a total rebuild, the work including new wheel bearings, steering head races, fork bushes, chains, tyres and spokes, valves, springs and guides, and a rebore +0.060". Notable features include 'pie crust' fuel and oil tanks; Webb forks; a Sturmey-Archer gearbox; a Binks bronze-bodied carburettor; and a CAV magneto. The engine turns over.

Following a period of inactivity, this motorcycle will require recommissioning and/or restoration to a greater or lesser extent before returning to the road and thus is sold strictly as viewed. Prospective purchasers should satisfy themselves with regard to this motorcycle's completeness, history, authenticity, originality and mechanical condition prior to bidding.
