Manufactured: 1935-1979 by Aldo Guazzoni
Founded in 1935 by Aldo Guazzoni (1908-1978), the Milano company built a 500cc machine powered by a Calthorpe engine. This was followed by lightweight motorcycles fitted with their own engines, and later they built three-wheelers. Subsequent to WWII Guazzoni was a Motori Morini dealer before returning to motorcycle manufacturing in 1950, building, among others, a 150cc machine for FBM.
Guazzoni continued building classy lightweight sports bikes throughout the 1960s and 1970s including production racers, mostly fitted with reversed cylinders allowing the exhaust to exit at rear. Manufacturing ceased in 1976.

Guazzoni Engines
The Guazzoni rotary-valve two-stroke engine with reversed exhaust came in many guises, mostly 50cc
The production racer had a six-speed gearbox and could pull up to 15,000 revs.
Cadetti 60 engine size: 37.5 x 45mm
There were also 98cc, 125cc and 150cc engines. A 250cc Gran Turismo was advertised but may not have seen production.

Tank appears very similar to that on Franco Bonadonna's Guazzoni Matta, so it's probably a c1968 model. Engine, exhaust, headlight all non-original. Value debatable.

guazzoni 50 - 1966
Had one of these at one point. Manufacuturer bore it out to 60 cc and it went like a flash. Seeing your site made me wish I had never given it away after it proved to be so finicky.

Sorry, I wish. I only have a bundle of find memories of flying down the road at 90 miles an hour on a 90 pound bike with the blistering sound of a spinning 2 cycle engine going at full tilt and being driven through without a
muffler. I am so lucky not to have killed myself. But when it got so temperamental that I had to kick it over 100 times to get it going, my interest waned.
