Lot Details
1934 Norton 490cc Model 18
Registration no. JH 8820
Frame no. 53793
Engine no. 59171
Introduced for 1923, the Model 18 was Norton's first overhead-valve production machine, and quickly established a reputation for both speed and reliability when a standard engine assembled from parts was used to set a host of records, including a new 12 hours mark. Improvements resulting from the racing programme were regularly incorporated into the production bikes, yet the Model 18 retained its essentially vintage characteristics until extensively redesigned in 1931. At this time Norton's sidevalve and overhead-valve singles adopted the rear-mounted magneto - already seen on the ES2 - and switched to dry-sump lubrication. Norton continued to fit Sturmey-Archer gearboxes and all models - with the exception of the ES2 - used an open diamond frame. Changes between '31 and 1939 included an additional drive side main bearing, revised cam gears, the adoption of Norton's own gearbox, and - in 1938 - a new cylinder head with enclosed valve gear. This matching numbers (frame and engine) Model 18 was registered on the 11th of July 1934 and restored between 1989 and 1991 and after completion was used for a short while before being placed in storage. Described as in 'mint' condition and said to be a lovely ride, the machine will require re-commissioning and the customary safety checks before returning to the road. Accompanying documentation consists of an old-style logbook and V5 registration document.
