During its production years, NSU introduced two versions of the Lambretta. The first variant, built until 1954, had a 123cc displacement, a top speed of 70 km/h (44 mph), and produced 4.5 PS of power from its single-cylinder two-stroke engine.

From 1954, the second variant featured a 150cc engine with a top speed of 81 km/h (50 mph), offering a more robust power output of 6.2 PS. In total, approximately 117,000 units of both versions were manufactured from 1950 to 1956.

The Lambretta scooters were available in four colors: lime green, beige, medium gray, and light gray.
