This 1957 NSU Prima III was purchased from the collection of well known scooter restorers Tom and Anna Giordano. NSU began producing the Innocenti Lambretta under license beginning in 1950, then introduced the Prima as their own design in 1956. This Prima III was originally equipped with a 146cc engine but has been bored out to the 175cc displacement of the higher priced Prima V. It has been restored both cosmetically and mechanically using many NOS parts acquired by the Giordanos from a former NSU dealer, and remains in good condition.
The scooter is in nice cosmetic condition with fresh paint in a period appropriate pastel green. The trim was restored with a combination of polished original parts and NOS pieces where available. Some of the trim between the two rear side panels is missing but there are no other significant flaws in the bodywork.
The clock and speedometer have been restored. The scooter is equipped with an electric starter and all lights are in working order.
The dual bicycle style seats for the rider and pillion passenger are in very good condition. The grab handle for the back seat rider is still in the protective plastic wrap.
The frame was also cleaned and repainted as part of the restoration, as were the wheels. New tires were fitted.
The mechanical components of the scooter were all refurbished, with the following work performed:
- Fully rebuilt engine
- Transmission disassembled with any worn parts replaced as needed
- Rebuilt carburetor
- Fuel tank cleaned out and new fuel lines installed
- All cables replaced
- Brake system rebuilt
- Suspension rebuilt
The engine is a 175cc unit that starts easily and runs well, and with all the mechanical systems refreshed the scooter is said to ride nicely.
The scooter is sold with a Washington state title. These German built NSU scooters are an interesting alternative to the more common Vespa and Lambretta scooters of the era. This example has been nicely restored with good attention to detail and is being offered at no reserve.
