Norton debuted a new, over head cam single cylinder engine designed by Walter Moore during the 1927 season. Conceived in response to rumours of similar designs being developed by rival manufacturers , the new power unit retained the 79 x 100mm dimensions synonymous with the Norton marque. The over head cam was driven by a shaft with bevel gears mounted on the right hand side of the engine. The bottom end of the engine was similar to those employed by its over head valve cousins except for the drive arrangements for the camshaft drives. The top end featured a distinctive cambox with an inspection cover that allowed access to the top bevels. The new engine was installed in a new cradle frame that became a benchmark for handling in the rigid era.

The new machines showed considerable promise at the 1927 TT, Alec Bennett won, although Woods retired with clutch trouble. The Norton team, and Woods in particular, did well in other events that year, prompting the introduction of production version of the new machine for the 1928 season. Typed the CS1, the new over head cam model shared its frame and cycle parts with the equally new overhead valve ES2. The CS1 was joined by a 350cc version, the CJ, during 1928. The Moore CS1 and CJ were phased out early in 1930.

Poor racing results in 1928 and much of 1929 resulted in Moore moving to NSU in mid-summer 1929 and the return of former works rider Joe Craig to manage the racing side of the business. Craig and Arthur Carroll, an existing Norton design office employee, worked together to come up with the so-called Carroll OHC engine, shown at the 1929 Motor Cycle Show, and went into production in 1930.

During 1930 Norton continued to use the CS1 designation and quite a large number of such machines were produced, many for regular use fitted with magdynamos etc and some for racing. During the rest of the decade, the CS1 continued in production as a sporting machine, while its place for faster performance and racing was taken over by the International Models, introduced in late 1931.

Restored by the previous owner prior to the purchase and used on many VMCC events throughout ownership, we have been advised the Norton is running well and is offered with a current V5C and some old MOT certificates.
