Overview Lambretta 150 D/LD

The Lambretta D and LD series comprised numerous variants, which today are usually categorised as versions 1, 2 and 3. However, the total number of versions increases when the globally produced models are taken into account. The differences between the various D models were often minimal, while the LD models are easier to identify due to their modified body shapes. Given the numerous modifications not documented in the production history, the descriptions of the D and LD models should not be considered complete or absolutely accurate.

Lambretta 150 D/LD model history

Model 150 D & LD (Version 1)

The first version of the Lambretta 150 LD from 1954 was characterised by an aluminium Handlebar, an electrical system that did not require a Battery and consequently no Rectifier. It also had Gudgeon Pins with a diameter of 14 mm, a cylindrical Distributor on the Flywheel and an Exhaust fitted with a chrome-plated Silencer.

Model 150 D (Version 2)

In October 1954, the range of 125cc Lambretta D models was extended to include a more powerful 150 cc model. This larger Engine was characterised by Cylinder and flywheel covers similar to the Lusso models. The previous direct air cooling and the single Teleflex gearshift cable were abandoned; instead, two "push and pull" cables were used. The exhaust system of the 150cc model was revised and given a chrome-plated Silencer, affectionately known as the "coffee pot". For the first time, a Silencer was inserted into the torsion bar suspension to improve ride comfort. With the increased power of the 150 cc Engine, the top speed also increased to around 90 km/h, with Innocenti continuing to state the fuel consumption at a remarkable 60 kilometres per litre.

Model 150 D (Version 3)

Compared to the second generation of the Lambretta 150 D, some adjustments were made, including the integration of a battery that powered the parking lights, Horn and Brake Light. This Battery found its place on the side of the Kickstart Lever, in a specially designed compartment next to the toolbox. The Exhaust was converted to a single Silencer model, eliminating the additional silencer from the previous series. The Legshields were adorned with a D150 Badge in chrome, while the Lambretta lettering remained as a Sticker on both sides of the fuel tank.

Model 150 LD (Version 2)

Similar to the Lambretta D model, the LD was also equipped with a more powerful 150 cc Engine. This increase in engine power led to an elevation of the top speed to around 90 km/h. As standard, this Lambretta had a toolbox mounted on the inside of the Legshield, which provided space for the Speedometer and an additional display. This second display, often a timer and a rarity today, was an optional extra. In contrast to earlier models, where the toolbox was concealed under the Side Parts, it was now located behind the rear seat and could be accessed from the outside. The 150 cc variant was also characterised by a shield-shaped Emblem on the Legshields, similar to that of the 125 cc model, but in blue and white with the marking 150.

Model 150 LDA (Version 2)

A 12-volt system was implemented for the electric start version of the LD, which was achieved by connecting two 6-volt batteries together. To create the required space for the batteries, a special elevation was added to the frame behind the rear seat. A newly developed and more reliable starter was mounted under the rear Footboards. The epicyclic starter, which was standard in the third version of the LDs, was inserted in later versions. Double seats were standard equipment on these models. By the end of production in November 1956, a total of 2,020 units had been produced.

Models 125 & 150 LD (Version 3)

In January 1957, Innocenti presented the third series of the Lambretta LD with engine variants of 125 cc and 150 cc. These new versions retained the engine characteristics of their predecessors, but were given an additional epicyclic kickstarter mechanism. The Legshields were now emblazoned with chrome-plated model identification, either LD125 or LD150, while the traditional Innocenti horn badge was carried over from the earlier models. The Horn found its place in a newly designed casting on the Handlebar, which not only provided neat Guidance for cables and wires, but also integrated a Speedometer. The rear of the scooter was visually revised and given a more aerodynamic design with an attached cast rear light unit. The door to the toolbox was positioned directly in front, between the Rear Light and the rear seat. Air was now supplied via a Rubber Tube leading to the rear of the Frame, which minimised intake noise and improved airflow. This allowed the scooter to achieve higher revs and better performance.
