LI150 SPECIAL - 150cc

A classic 1965 Lambretta LI150 Special in Silver, representing one of the most desirable sport-oriented versions of the Series 3 LI. Introduced as a sportier alternative to the standard LI, the 150 Special combined distinctive TV-inspired styling with a more powerful 148cc engine.

This example has been fully restored, preserving the clean proportions and unmistakable character of the original Italian LI150 Special.

The Mid-60s Sport Benchmark: Lambretta LI150 Special (1963 to 1966)

Introduced in late 1963 and produced through 1966, the Lambretta LI150 Special (commonly designated LIS 150, frame prefix 150LIS) filled a crucial sporting role in Innocenti's line. Created to bridge the gap between standard touring LI models and the high-spec flagship TV range, the 150 Special brought elevated styling, sharper handling, and responsive road performance to mid-capacity scooter enthusiasts across Europe and North America.

With roughly 70,000 units produced at the main Innocenti facility in Milan, the LI150 Special became a staple of 1960s rally culture and Mod lifestyle. As a mature 1965 production model finished in factory-correct Metallic Silver (Argento Metallizzato), this machine captures the LI150 Special at its aesthetic peak, presenting a harmonious blend of Slimline bodywork and close-ratio mechanical performance.

Slimline Bodywork and TV-Inspired Styling Cues

The visual appeal of the 1965 Lambretta LI150 Special relies on its angular, aggressive lines adapted directly from the higher-capacity TV Series III models:

• Octagonal Headset Casting: Distinctive angular handlebar housing fitted with an octagonal headlight bezel and crisp speedo display, setting it apart from the round headset of standard LI models.
• Squared Front Mudguard and Tapered Horn Nose: Aerodynamic front sheet metal components, including a lower-profile front horn grille and a squared-off front mudguard for a crouching, athletic aspect.
• Double Finger-Flash Side Cowls: Tapered side panels decorated with polished aluminum front and rear finger flashes that accentuate its low, athletic profile.
• Metallic Silver Factory Finish: Adorned in iconic factory Silver, complemented by classic "Special" script badging mounted across the leg shield and floor runners with rubber inserts.
• Tubular Steel Spaceframe: Built around Innocenti's heavy-gauge central-tube frame architecture, providing high torsional stiffness, low center of gravity, and neutral cornering feedback.

148cc Engine Performance and Close-Ratio "Pacemaker" Gearbox

At the mechanical core of the 1965 LI150 Special is an air-cooled, single-cylinder two-stroke 148cc engine mounted horizontally within the central chassis frame. Innocenti engineers raised the compression ratio to 7.5:1 and optimized cylinder porting, boosting power output to 8.25 horsepower at 5,300 RPM.

Breathing through a Dell'Orto SH/18 carburetor, the 150 Special delivers lively acceleration and cruising speeds reaching 58 mph (93 km/h). The defining mechanical feature of the model is its famous close-ratio 4-speed transmission—widely known as the "Pacemaker" gearbox. By narrowing the ratio spacing between third and fourth gear, the Pacemaker cluster eliminates power drops during gear shifts and maintains engine momentum on steep inclines. Power reaches the rear 10-inch wheel via an oil-bath duplex chain drive, supported by trailing-link front suspension and a rear hydraulic shock.

Master Restoration and Historical Fidelity

This 1965 Lambretta LI150 Special has undergone a comprehensive ground-up restoration executed to preserve total historic accuracy while delivering turnkey reliability:

• Turnkey Operational Standard: Fully reconditioned to provide immediate road enjoyment, rally participation, or display without the downtime or complexity of an ongoing build project.

Investment Potential and Collector Value

For classic Italian vehicle collectors, the 1965 model year represents a prime period in Innocenti's mid-1960s production run. Benefiting from mature assembly standards while retaining the unadulterated aesthetic charm of Series III manufacturing, a fully restored 150 Special in iconic Silver remains a favorite in international collector circles.

Investing in a 1965 LI150 Special represents a sound commitment to Italian industrial heritage. Whether displayed at concours events or ridden on classic rallies, a completed Pacemaker Special stands as a functional, highly authentic centerpiece in any serious vintage vehicle collection.
