Negrini mopeds, scooters and small motorcycles have been made in Modena, Italy since 1950.
1. “From bicycle to anti-dive” a history of Negrini, from “Motociclisimo d’Epocha” magazine April 2005
2. Negrini was founded by Pietro Negrini in 1950. The first Negrini mopeds had IMC (Industria Meccanica Calzolai) 3-speed engines.
3. Negrini made 61,632 units in 1960, 132,548 in 1965, and 320,000 in 1970. Pietro Negrini’s son Mauro took over the company in the 70s.
4. Here is Mauro Negrini, on a fishing trip, 65 years old in 2005, still with the passion. Some Negrini’s had CO.ST.A. anti-dive front suspension.
1. 1962 Negrini Gioietta
2. 1978 Negrini Leprotto (Italy model) provided by Primo of Budoia (Pordenone)
3. ’70’s Negrini Boomerang (Italy model)
Negrini USA
Negrini USA was formed when the US laws changed in 1976, and moped demand in the US was very high because of fear of high gas prices. Some time around 1979 Negrini USA Inc became Marina Mobili, in Moonachie New Jersey.
Negrini mopeds are rare in California because they had no west coast distribution center. So out of 150 moped shops in the greater Los Angeles area, none, or almost none, were Negrini dealers.
1. This could be Marina Mobili’s first flyer, side one.
2. Negrini MX Sport, Harvard and Gazelle, side two.
Marina Mobili The business location on 146 W Commercial Ave, in Moonachie NJ, that was originally called “Negrini USA Inc”, became known as “Marina Mobili Inc”. The phone number 201-438-5700 that was originally for Negrini USA Inc, became the phone number of Marina Mobili Inc. From this it appears that Negrini USA changed their name to Marina Mobili. The most likely reason is they wanted to expand into selling more brands than just Negrini. They went on to become the biggest independent moped importer in the USA, taking on dozens of brands of bikes and components, mostly Italian and American at first. Soon they expanded to parts from France, Germany, Taiwan, Holland and Spain. So this flyer is historically important. This material was donated by Mr. B. Small of Maryland USA, for you to use and enjoy!
1. Negrini/MMI early flyer for moped dealers
2. Dealer Flyer shows MMI was Negrini
3. MMI made this Negrini brochure for USA moped dealers
Marina Mobili’s first product brands were Bosch, CEV, Cintin, CO.ST.A., Dansi, Dellorto, Domino, G.E., Grimeca, Huret, Kryptonite, Master, Michelin, Minarelli, Morini, Negrini, and Pirelli brands. They are listed on this early flyer for moped dealers.
1977 models
The Negrini Leprotto was the low cost version of the Gazelle, with painted fenders instead of polished stainless steel, an all steel standard fork instead of the stiff and precise CO.ST.A. motorcycle type fork (cast aluminum with steel tube), and with P.V. controls with plastic levers instead of Domino controls with polished stainless steel levers. Both the Leprotto and Gazelle had the same detachable gas tank and classic Italian moped steel tube step-thru frame.

Right, 1978 Negrini MX Sport (top tank) with standard Morini MO1 engine.
1978 models
Other than the Leprotto, all Negrini mopeds had high quality CO.ST.A motorcycle type suspension for precise control. Other than the Leprotto, all Negrini mopeds had high quality Domino “70’s chrome” controls with polished stainless steel (SS) levers that look like chrome. Of course, like an Italian meal is not complete without pasta, so all Negrini mopeds had high quality CEV electrical equipment, Dansi or Bosch ignition, Grimeca wheels and brakes, CBA exhausts, and for desert, Dellorto S.H.A. 14/12 (or 14/9) flat slide carburetors facing to the right side.

1977-78 Negrini MX Sport
This MX Sport is equipped with a Bosch ignition coil, while the Gazelle and Harvard have Dansi ones. That means the magneto might also be Bosch on some models, Dansi on most others.
