A new 250cc machine is added to the range taking it to eight models in
all, including the 350cc OHV Model 8, OHV Model 9 in 500cc and 600cc
versions, and the side-valve Lion also available in 500cc and 600cc
versions. The 500cc OHV Model 95 is made available in fast, road-going trim
as the 95L, and in sportier racing trim as the 95R.
The new 250cc model has a distinctive crank case which encloses the oil
pump, and a bought-in Burman gearbox. It has a high, double camshaft engine
which earns it its 'Hi-Cam' name, whilst its pronounced bulbous silencer is
probably its most distinctive feature. All this is held together in a
duplex, cradle frame - all features that point to the future design for the
model range as a whole.
The Model 95 gets larger 8 inch brakes, improved forks and a stiffer
frame to assist handling at speed.
The Model 95 has a large cut-away tank (for the
saddle), whilst other models retain the standard tank with inset oil gauge
and clock (except the 250cc model which has no inset items)
26 inch wheels are standard, except for the Model 95
which has larger, 27 inch wheels.
Sunbeam 'fish tail' silencers are common across the
Engine and gearbox
There is a new alloy cylinder head for the side-valve engines, plus a
complex, Sunbeam-patented decompressor for all 500cc and 600cc machines,
both OHV and side-valve.
The Model 8 gets a four-speed gearbox, which was
introduced for other models in 1932.
