MODEL A - 125cc

A rare and historically important 1948 Lambretta Model A in Olive. Also known as the Model M, the Model A was the first Lambretta to leave the Innocenti factory and represents the beginning of the Lambretta story.

This example has been fully restored, preserving the distinctive early Lambretta design, compact proportions and simple mechanical character of this pioneering Italian scooter.

The Genesis of a Legend: Lambretta Model A / Model M (1947 to 1948)

Produced from October 1947 through October 1948, the Lambretta Model A (designated internally as the Model M, short for Motoleggera) is the founding father of the entire Innocenti scooter saga. Conceived in the aftermath of World War II by industrialist Ferdinando Innocenti and engineered by aeronautical pioneers Cesare Pallavicino and Pier Luigi Torre, the Model A was created to provide cheap, reliable personal transport to rebuild post-war Italy.

With only 9,669 units ever produced at the original factory in Lambrate, Milan, surviving examples are exceptionally rare. As a final-year 1948 production unit finished in factory-correct Olive, this machine captures the pure, unadulterated birth of the Lambretta brand, serving as a priceless historical artifact for top-tier motorcycle museums and world-class collections.

Pioneering Open-Frame Architecture and Model A Design Details

The visual architecture of the 1948 Lambretta Model A is defined by extreme mechanical transparency, aircraft-inspired engineering, and functional post-war minimalism:

• Pressed-Steel Section Frame: Built on a unique structural chassis made of two square-section pressed steel halves welded together, preceding the central tubular frames of later models.
• Direct Foot-Operated Gear Change: Features an unassisted, floor-mounted pedal gear selector—a short-lived configuration unique to the Model A before hand-twist controls were adopted.
• Minimalist Shielding and Open Layout: Compact, flat front leg shields with an entirely open engine area, offering zero bodywork clutter and direct visual exposure to the mechanical running gear.
• Authentic Olive Paintwork: Finished in period-correct industrial Olive, capturing the exact utilitarian aesthetic of late-1940s Milanese production.
• Dual Telescopic Front Suspension: Aircraft-style front forks using exposed telescopic fork tubes with internal springs, riding on tiny 7-inch split steel wheels.

123cc Engine Engineering and Bevel Gear Drive

At the mechanical heart of the 1948 Model A is a cast-iron, air-cooled single-cylinder two-stroke 123cc engine mounted vertically ahead of the rear wheel. Producing a modest 4.1 horsepower at 4,500 RPM, the engine is mated to a Dell'Orto MA13 carburetor, reaching a top speed of 40 mph (65 km/h).

Power transfers through a 3-speed manual transmission operated via the unique foot pedal gear shift on the right floorboard. Final drive is accomplished via a direct shaft setup enclosed within the aluminum swingarm, completely eliminating drive chain maintenance. Suspension at the rear is entirely rigid, relying on a sprung dual-saddle system and 7-inch tires fitted with internal expanding drum brakes to absorb road irregularities.

Master Restoration and Historical Fidelity

Restoring a 1948 Model A requires specialized historical knowledge due to the complete uniqueness of its first-generation castings, foot-shift linkage, and 7-inch running gear. This 1948 example has undergone a museum-grade restoration preserving complete historical accuracy:

• Chassis & Sheet Metal Preservation: Careful structural restoration of the original two-piece welded pressings and front leg shield, maintaining original factory weld seams and panel thickness.
• Reconditioned Mechanical Assembly: Full mechanical rebuild of the original 123cc vertical two-stroke engine, 3-speed shaft-drive system, and foot-pedal shift linkage to operational factory standards.
• Period-Correct Detailing: Refinished in period Olive with authentic early-type Innocenti badging, period-correct rubber controls, and fully restored 7-inch wheel assemblies.

Ultimate Collector Distinction and Historic Value

For serious vintage vehicle purists, motorcycle historians, and Italian design collectors, an authentic 1948 Lambretta Model A represents the absolute holy grail. As the foundational machine that launched one of the most celebrated names in two-wheel history, an original Model A commands unrivaled prestige.

Investing in a fully restored 1948 Model A means owning a physical piece of post-war Italian industrial heritage. Whether exhibited in museum displays or presented at premier international concours d'elegance events, this founding masterpiece stands as an irreplaceable monument to mid-century engineering bravery.

Conclusion: The Founding Pillar of Lambretta History

The 1948 Lambretta Model A remains an immortal monument to post-war ingenuity, mechanical simplicity, and visionary industrial design. Fully restored in period Olive while retaining its original Italian soul, this turnkey Model A offers an unrepeatable opportunity to own the ultimate origin piece of classic Lambretta history.
