Moto Guzzi 250 Airone Sport
Moto Guzzi's origins can be traced back to WWI, when a trio
of motorcycle enthusiasts serving with the Italian Air Force
hatched a plan to start a business: Giorgio Parodi would secure
the finance, Carlo Guzzi would design the machine, and Giovanni
Ravelli would race it. Sadly, Ravelli died in a flying accident
soon after the war's end, leaving Parodi and Guzzi to found what
would become one of the most exalted of Italian marques at
Mandello del Lario, close to the shores of Lake Como.
Carlo Guzzi's first prototype motorcycle of 1919 was unconventional in so far as its single-cylinder engine was installed horizontally, and by the end of the 1930s the 'flat single' had established itself as a Guzzi hallmark.
The prototype Guzzi was exceptionally advanced for its day: unitary
construction of the 500cc engine and gearbox, over-square bore/stroke, geared
primary drive, an overhead camshaft, and four valves per cylinder being just
some of its salient features. However, the Normale (standard) model that entered
production in 1921 was necessarily less ambitious, the most obvious difference
being its engine's inlet-over-exhaust valve arrangement, adopted to reduce
costs.
Guzzi recommenced production post-WW2 with range of updated pre-war designs,
which in the case of the 250cc Airone (heron), first introduced in 1939, meant
it gained a telescopic front fork, larger diameter brakes, and an
aluminum-alloy cylinder barrel and 'head. In 1949 a Sport version became
available; the original being renamed Turismo. Boasting a higher compression
ratio and larger carburetor, the more powerful Sport offered a 73mph top speed
and the ability to cruise at 60mph all day, and remained a top-seller well into
the 1950s. 'Robust Italian machine capable of very hard driving: remarkably
light petrol consumption' was how Motor Cycle magazine summed up the Airone
Sport after testing one in 1949.
