The first model of the series was the B40 Star, introduced in 1961.
The new 350 cc engine had 21 bhp, which gave a cruising speed of 50 - 55 mph and a top speed of 75 mph.
The Star had deeply valenced, painted mudguards; metal fork shrouds and the headlamp was fitted in a nacelle.
Finish was red with black frame and forks or all black.
American variants had chrome sides to the petrol tank.

In 1962, the big end was changed from plain bearings to roller bearing, and in 1965 the points were moved from the 'distributor'-type device behind the cylinder to the timing case, and the clutch operating mechanism redesigned.

Very few machines were made in 1967, its final year.
These machines were fitted with a roller bearing timing side main bearing.
These engines, prefixed BD40G, are generally acknowledged as having the most robust bottom end.

The model was initially known as the Star Sportsman in the US, but this was changed to the Star in 1962 ahead of the SS90 model being launched.
In 1964 the name was changed again in the US to the Super Star.
