Description
Sunbeam 1932 Model 9A 599 cc OHV frame # D12427 engine # PP1060A
The first OHV production Sunbeams were listed as the model 8 (350cc) and 9 (500cc) in 1924.
The model 8 with bore/stroke dimensions of 70×90 mm was an excellent sporty tourer, but stayed somewhat in the shadow of its more glamorous big brother, the 80×98 mm Model 9, which stayed in production till 1939.
From 1932 on a 600 cc version (Model 9A) was marketed , with engine dimensions of 88×98 mm, giving 599 cc.
New features for 1932 were: Sunbeam 4 speed gearbox and a new fork with revised brake, a tank top panel which holds Smith clock and oil pressure gauge and a new rocker box – with feed pipe from the oil pump – with fully lubricated rocker gear.
The clutch is now operated with a quick thread on the front chain case, doing away with the typical Sunbeam bridge over the output sprocket.
The 9A has 26 x 3.50 tyres, the Model 9 is standard equipped with 26 x 3.25.
This restored Gentleman’s mount is fully equipped with electric lighting, oil bath chaincase and speedometer.
