Navigator
350cc
1961 - 1965
1961 Model 1961 Model 1962 De Luxe Model
Introduced at the 1960 Earls Court Show in Standard and De Luxe versions, the Navigator is a larger version of the Jubilee, easily recognised by the Roadholder forks and an 8" Dominator front brake.
It had revised frame geometry for extra strength and a cylinder block cast in one piece, compared with the Jubilee's two separate castings; although both models had two part cylinder heads.
Early versions had a two tone paint job, dove grey / black on the De Luxe and dove grey / blue on the Standard. From October 1962, the Standard's colour options were changed to black and polychromatic blue, black seats with white piping were fitted, and after the move to Plumstead in 1963, production of the De Luxe ceased at the end of that year. Wider front forks were fitted and a steering lock, before the last Navigator came off the production line in 1965.
The top speed is just under 90 m.p.h. with petrol consumption in the mid '50s or better.
