Historical Notes of the Marque

Count Renzo Rivolta, born in London in 1908, purchased the Isothermos factory in 1939, and moved it from Genoa to Bresso (Milano) in 1942 after it was bombed. Isothermos built refrigeration and railway equipment. Motorcycle production began in 1948. The firm built scooters and motorcycles including Isoscooter, Isomoto, Furetta and the Isocarro, the latter a three-wheeler. There was also a an Isetta microcar which was licenced to builders in several countries including France, Spain, UK, Germany, Belgium and Brazil. The BMW Isetta is by far the best known of the variations and some 130,000 of these were built in Germany.

Their first model was the 65cc Furetto scooter which struggled to achieve 50 km/h and was soon shelved.

This was followed by the 125cc Isoscooter, capable of a genuine 75 Km/h. Powered by a two-stroke along the lines of the Puch "Twingle", it had a similar appearance to the Furetto but did considerably better in the marketplace due to both its acceptable performance and modern suspension.

In later years the firm turned to sports cars powered by American GM and Chevrolet V8 engines.

1953 ISO 125 Scooter
My friend has a 1953 ISO scooter that he purchased as a student in Milan and now lives in New Jersey in the USA. After 40 years he retired and we are now trying to get the scooter to run. The cylinder cranks over but the spark plug wire is broken at the point where it enters the magneto. Do you know where can we purchase the wire?
Also, is there a place on the engine to add oil to the crankcase?
Thank you for any information you can provide.
