Launched in 1960 at the
Earls Court Motorcycle Show the Navigator was a development of the Norton Jubilee. The engine was enlarged in bore (from 60 to 63mm) and stroke (from 44 to 56mm), to give a capacity of 349cc. The cylinders, separate on the Jubilee, were now a single casting to improve oil retention, but the cylinder heads continued to be separate. Norton
Roadholder forks and eight-inch brakes were fitted to replace the Jubilee's lightweight front end. The down tube on the frame was stiffened to improve handling and deal with the power increase to 22bhp. to enter a standard Norton Navigator in a race at
Silverstone race track where it recorded on the straight with only minor carburettor modification. The 1960 model was still aimed at the Jubilee market, with enclosed rear end. In 1961, optional extras included a handlebar-mounted fairing and screen, as well as large legshields and panniers, giving it the enclosed look popular at the time. Early Navigators came with two-tone paintwork in grey and black for the "De Luxe" and grey and blue for the "Standard" model. From October 1962, the Standard's colour options were changed to black and polychromatic blue, with black seats with white piping. When Norton production moved to
Plumstead in 1963, production of the De Luxe ended, but the Standard model continued with wider front forks and a
steering lock, until Navigator production ended in 1965 with the collapse of Norton's parent group,
Associated Motor Cycles. ==Norton Electra==
