The Moto Guzzi Sport is a motorcycle that the Italian company Moto Guzzi produced from 1923 to 1939.
history
In 1923, based on the manufacturer's first racing machine, the C2V , derived from the normal series model , a sportier motorcycle called Sport was created , which was initially set aside for the normal. A year later, it completely replaced this first production model. The Sport was the first Moto Guzzi to be equipped with electrical lighting on request and was also the manufacturer's first model to which a sidecar could be attached.
In 1929 the successor Sport 14 replaced the first Sport, which was subsequently also referred to as "Sport 13". It was equipped with an improved parallelogram fork and a drum brake in the front wheel. The engine power increased slightly.
The Sport 15 followed in 1931 , which differed from its predecessor Sport 14 in particular in the saddle tank instead of the previous plug-in tanks. The electrical lighting system was standard on her. The sport was built in this form until 1939. Since 1934, parallel to the counter-steered sport, the overhead steered V-models , which completely replaced the sport in 1940.
While the Sport produced 4107 copies in the years 1923–1928, the Sport 14 had 4285 units in 1929 and 1930. The Sport 15 was built in 1931-1939 in 5979 pieces.
technology
Engine and drive
The Sport has an air-cooled single - cylinder four-stroke engine with a horizontal cylinder. On the left stump of the double-bearing crankshaft there is a smooth flywheel that runs outside the housing. A spur gear attached behind it drives the basket of the multi-plate oil bath clutch mounted on the transmission input shaft. The three-speed gearbox is operated with a gear lever on the right side of the tank. The transmission is connected to the rear wheel by a machine chain.
The hanging exhaust valve is controlled by the camshaft below via a bumper and a rocker arm , the vertical intake valve is controlled directly ( counter control ). To switch off the engine, the bumper is pushed forward using a valve lifter so that the exhaust valve opens. The magneto is driven by a spur gear on the right side of the engine. The ignition timing is adjusted manually.
The mixture is prepared by a flat-flow carburetor with a round slide, 36 mm passage and without an air filter. The nickel-plated (from approx. 1928 chrome-plated) exhaust pipe is pulled back on the left side of the machine. In the Sport 14 and Sport 15 models, it ends in a cigar-shaped silencer.
Frame and chassis
The Sport has a double-loop tubular frame with an unsprung mount for the rear wheel. The front wheel sits in a parallelogram fork with a barrel spring .
Tanks
The petrol tank of the Sport, which was built until 1928, is a plug-in tank and has a volume of 10 liters, the oil tank underneath has a volume of 2.5 liters. The oil tank is connected to the cylinder head and the oil pump in the engine's dry sump by nickel-plated copper pipes. In the Sport 14, the volume of the petrol tank increased to 11 liters and that of the oil tank to 3 liters. The Sport 15 also has an 11 liter gas tank, but in the shape of a saddle.
Wheels and brakes
Sport's 26 ″ wheels are wire-spoke wheels. The rear has half-hub drum brakes . It is operated via a foot lever on the left side of the engine and a linkage or via a cable from the handlebar. The Sport 14 corresponds to Sport in wheel size and rear brake, but has a half-hub drum brake in the front wheel as standard, which is operated with a cable from the handlebars instead of the rear brake. The Sport 15 has 19 ″ wire-spoke wheels and the same brake equipment as the Sport 14.
Materials
The engine / gearbox housing is made of aluminum, the cylinder and cylinder head are made of gray cast iron . The frame, the front fork, the tank and the mudguards, on the other hand, are made of sheet steel.
Painting, surface treatment and emblems
The sheet steel parts of the Sport are painted in olive green. Tanks and mudguards have gold-colored lines. On the tank sides of the machines there are gold-colored Moto Guzzi emblems as decals. The gray cast iron parts of the engine are burnished. The Sport 14 also corresponded to this picture, but was painted red. The Sport 15 was also available in red paint, but also as a luxury model with chrome-plated and partially painted petrol and oil tanks.
