Lambretta Junior

In 1964, Innocenti launched the Junior series, a completely new family of scooters. The simple scooters were intended to attract new groups of buyers at a lower price.

The concept of the vehicles has some similarities with Piaggio vehicles. For example, the chassis is self-supporting and access to the air filter is located under the driver's seat beneath a small plastic tub. The engine, on the other hand, is located centrally in the frame and is clearly based on the design of the Li engines. The cylinder of the Juniors is different. Depending on the model, a seat bench, a single seat or two single seats were installed.

The engine is hidden under side covers, most of which had external locking levers. The rubber parts were completely gray, except for the kickstarter and stand feet, which were also black.


J125 Starstream & Super Starstream

From May 1966, the lifted J100/125 was marketed as the Starstream. New features included a narrow leg shield, a new seat and the very attractive Stellina lettering with the star. The engine is familiar from the J125, but now has a four-speed gearbox. The paintwork is two-tone. The base coat is set off with either red or blue side hoods and cascade. The side bonnet catches change over time from levers to inside catches.

The "Super Starstream" was specially designed for the English market. Here, the advantages of the conventional Starstream were joined by a movable mudguard and a very successful cascade. Thanks to the change to a four-speed gearbox, the Starstream and Super Starstream accelerated quite quickly and reached a top speed of 87 km/h. Production of the Starstream and Super Starstream was stopped in April 1966.
