This Stevenson-designed 250  ( bore x stroke= 64x70mm)  was introduced at the November 1934 Olympia Show. 

The bike attracted much attention because of its sporty looks: large carburettor, hairpin valve springs and  “ OHC look-alike” timing case. This was the first Sunbeam with a proprietary gearbox, made by Burman. 

The long bulbous silencer has a special, deep exhaust note. 

Although the press wrote favourably about this new design, the model 16 became not a great seller and was dropped from the line in 1936.
