The 500 cc DBD34 was introduced in 1956, with clip-on handlebars, a finned alloy engine with a newly designed head, chrome plated fuel tank, 38 mm ( 1 1/2" ) bell-mouth Amal carburettor and swept-back exhaust.
The DBD34 had a 110 mph (180 km/h) top speed.
The Gold Star dominated the Isle of Man Clubmans TT that year.
Later models had an ultra close-ratio gearbox (RRT2) with a very high first gear, enabling 60 mph (97 km/h) plus before changing up to second.
Amongst the options available were a tachometer and a 190mm full width front brake that gave a larger lining area than the standard 8" single sided unit.
A scrambles version was also offered.

Production ended in 1963.
