250 Raid The initial 250 model was propelled by a 247 cc
air-cooled,
single-cylinder OHV engine.
Bore and
stroke was 69 x 66 mm and
compression ratio was 7.2:1. Breathing through a 24 mm
Dell'Orto carburettor, the engine produced 14 bhp (10.4 kW) at 5,600 rpm. A geared primary drive fed the power to a 4 speed
gearbox. The
frame was MV's usual arrangement of a double cradle made of tubular and pressed steel.
Telescopic front forks were fitted and a
swinging arm with hydraulic
shock absorbers at the rear. 200 mm
drum brakes were fitted front and rear. The machine was finished in black with red detailing. Top speed was 115 km/h (72 mph).
300 Raid In 1959, in an attempt to recover the poor sales of the 250, a 300 cc version was introduced. The bore was increased to 74 mm and the stroke to 70 mm, which gave a 301 cc displacement and an output of 16 bhp (12 kW) at 5,000 rpm. To give a similar fuel consumption to the 250, the carburettor was reduced to 22 mm. A new
petrol tank,
mudguards and
exhaust were fitted, otherwise the cycle parts were the same as the 250. was produced in limited quantities for Italian Armed Forces in 1961. The model was fitted with two individual
saddles and finished in a drab green. was introduced, but this variant was not taken up by the police. ==Spanish production==
