"With a history stretching back almost to the very dawn of motorcycling itself, the Norton single is without doubt the greatest of all the over-the-counter production racers." - Mick Walker, Manx Norton.

Dubbed 'Manx Grand Prix' in 1939, what would become the best-known racing motorcycle of all time had become simply 'Manx' when production resumed in 1946. Norton's over-the-counter Manx racers were much the same as their pre-war counterparts, with single-overhead-camshaft engine, 'square' cylinder head finning, upright gearbox and plunger-suspended 'garden gate' frames. Only the presence of the Roadholder telescopic front fork readily distinguished them from the '39 machines. 1949 brought the first significant change in engine specification, the Manx gaining a double-overhead-camshaft 'head like that enjoyed by the works bikes for many years, but the major development was the arrival of the Featherbed frame for 1951. The works' adoption of the McCandless-designed duplex-loop swinging-arm chassis the previous year had given the Nortons a new lease of life in Grand Prix racing, and Geoff Duke duly took both the 350 and 500cc world titles in 1951. The cycle parts remained essentially unchanged from then on apart from the adoption of a double-sided, twin-leading-shoe front brake for 1962. Manx engine development, though, continued steadily, latterly under Doug Hele's direction, until production ceased at the end of '62, among the most significant design changes being the adoption of 'square' bore and stroke dimensions for 1954 and coarser-pitch bevel teeth in 1957. Loved and admired by all that have ridden one, the Manx Norton in its many forms is a mainstay of today's classic racing scene.

Purchased by the vendor's late father in 2004 and dry stored, this Model 30 Manx has not been used for at least five years and will require re-commissioning before further use. Concours awards include 'Best in Show and 'Best Competition' at the East Kent Classic in 2006, and 'Best in Show' at the Cardiff Motorcycle Show in 2011 (list available).
