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.
J50
There are three different versions of the J50. The first version, with a displacement of 50 cc and a three-speed gearbox, produces an impressive 1.47 hp and reaches a dizzying top speed of 40 km/h. The 10-inch tires were replaced by the 2.75-9" format in the second version. Although the J50 has a double seat as standard, there is no speedometer or steering lock. The third version introduced a four-speed gearbox and the frame was significantly modified. The leg shield became significantly narrower and more stable. The seat also became narrower to match. Despite the four-speed gearbox, the J50 does not get any faster.
The four-speed J50 was replaced in January 1968 by the J50 De Luxe, which again had the three-speed gearbox. The De Luxe has a sporty single seat and a rear luggage rack. The leg shield is framed with chrome edging. The latches on the side covers are similar to those on the DL series. The tires are now back on 3.00-10" tires.
