Moto Guzzi is the oldest European motorcycle manufacturer in continuous production. “Established in 1921 in Mandello del Lario, Italy, they played a historic role in Italy’s motorcycling manufacture, its prominence worldwide in motorcycle racing, and industry innovations—including the first motorcycle center stand, wind tunnel, and eight-cylinder engine.“ (from Wikipedia)
Towards the end of the 1960s, the arrival of Japanese manufacturers caused a crisis in the European motorcycle industry.
SEIMM: From 1967 to 1973 Moto Guzzi was owned by SEIMM Moto Guzzi. “By 1964, Moto Guzzi was in full financial crisis. Emanuele Parodi and his son Giorgio had died, Carlo Guzzi had retired to private life, and direction passed to Enrico Parodi, Giorgio’s brother. Carlo Guzzi died on November 3rd, 1964 — in Mandello, after a brief hosptial stay in Davos. In February 1967, SEIMM (Società Esercito Industrie Moto Meccaniche), a state controlled receiver, took ownership of Moto Guzzi. The SEIMM oversight saw Moto Guzzi adapting to a cultural shift away from motorcycles to automobiles. The company focused on popular lightweight mopeds including the Dingo and Trotter — and the 125 cc Stornello motorcycle. Also during the SEIMM years that Guzzi developed the 90° V twin engine — designed by Giulio Cesare Carcano — which would become iconic of Moto Guzzi.” (from Wheels of Italy)
Moto Guzzi mopeds: There are two kinds of Moto Guzzi mopeds, US models. They are mostly the same except for different frames, wiring and lights.
1978-79 Moto Guzzi (mono-tube): This is the mono-tube or tubone (thick tube with gasoline inside) Moto Guzzi, made by SEIMM Co., that is almost the same as the Benelli G2. See Benelli.
The 1978-80 mono-tube moped has a clockwise 3-wire Dansi 101813 magneto with an external ignition ground. So loose brake light wires can cause it to not run. See CEV/Dansi.
1980 Moto Guzzi (mono-tube): This is the same as the 1978-79 except for headlight is shorter, speedometer is in a black plastic housing above the headlight, side covers are black and not as long.
The ID plate says made in 1980, 1981 model
1977-80 Moto Guzzi Robin (sheet frame): This is a stamped sheet metal frame Moto Guzzi Robin, made by SEIMM Moto Guzzi S.p.A. Mandello del Lario Italy. It is the US version of the Moto Guzzi Chiù.
