Giuseppe Remondini worked in Italy with Alfa-Romeo, Moto Frera and& Nagas & Ray before moving to France and forming a partnership with Tito Rodolfo Jonghi, an Argentinian of Italian descent who presented himself as a doctor but was believed to be involved in the arms trade.

Initial machines were re-badged Nagas & Ray models, and by 1931 the first true Jongi models were completed.

Jonghi machines entered competition with quite outstanding results. They won the Bol d'Or of 1932, and later that year took the Grand Prix 350 event in Rome. In 1933 they gained a 24 hour record at Montlhery. Other world records followed including a sidecar record.

In 1933 Tito Jonghi left the firm and, with financial assistance from his father, Remondini renamed the business Les Constructions Mécaniques Remondini, Père et Fils.

1935 saw the acquisition of the Jonghi marque by the owners of Prester, the Eichel brothers. New models followed including a 175cc twostroke and a 100cc BMA. To demonstrate the durability of the 100cc two-stroke, it was ridden across the Sahara desert and as a result sales soared.

In 1944, after the Eichel's demise at the hands of the Nazis, the company was acquired by the SATAM company with Remondini as manager, and the machines rebranded as Motos Jonghi. Production resumed at a new factory in La Courneuve, initially with a BMA of 100cc and shortly thereafter a 125cc model was released. This was followed, in 1948, by an OHC 125cc model, the ACT, and in 1951 a 250cc machine appeared. 1953 saw the first appearance of their Polo 125, a machine very similar in appearance to the Moto Guzzi Galletto. This proved to be the last new model from Jonghi.

By the early 50s motorcycle manufacturers in France, as in Italy, were besieged by the success of lightweight cars - the Citroen 2CV in France, and the Fiat in Italy. Dozens, hundreds perhaps, of smaller motorcycle factories folded, among them Jonghi. They ceased production in 1957.

Guiseppe Remondini died in 1959. Arigo, his son, was the motorcycle mechanic for Jean Pierre Beltoise who was an International Grand Prix rider from 1962 to 1964 in 50, 125, 250 and possibly 500 cc classes. Although on paper his GP results do not look terribly impressive, he also won 11 French titles in three years. He and Arigo joined the Matra racing team (or, more likely the Rene Bonnet team and then Matra.)

October 28, 2000
Hello, I am in the UK, I have a 250cc Jonghi single twin port (2 Silencers) believed to be 1953. Frame 6551 Engine 4422 It has a single rubber seat, The sides of the petrol tank are chrome, the filler cap is a nice flip up type in aliminium, Full width ali hubs, plunger rear suspension,, Tool box on the right Ali crankcases, barrell and head. White kneegrips on the tank, with pimples, front fork lower legs are chrome, tops and headlamp brackets in alloy.

It is believed to have broken down and left by the roadside, recovered by the Police, never claimed by the owner, sold at auction, then sold to a number plate dealer, put back into another auction, which is where I bought it in 1997.

If you give me an address i will send pictures, so that you can identify it for me, or anyone that might know the model type.

I am interested in anything about it, I hope someone can help me ,

Many thanks Brian McDonough.

PS, Is there a club for Jonghi's? Is there a Jonghi Expert? Is there any literature on Jonghi's?.
