Lambretta Li Series II

General Information

With the LI Series II, the LI range had finally come into its own. The Series II LI was the most commercially successful Lambretta ever made. In terms of sheer numbers produced, Innocenti would never equal the LI 150 Series II.


In terms of styling, the Series II was not substantially altered from the LI Series I which preceded it. The most notable alteration was that the headlight was moved from the fixed position on the front horncasting, up to the front of the handlebars where it would be able to move with the steering of the scooter. Not only was this a safety improvement, but it helped create an aesthetic harmony on the scooter, and helped to balance out the sheer size of the legshields and front mudguard.

The handlebars themselves were also radically altered to accommodate the change. The speedometer retained its earlier round shape, but was sunken into the top of the bars, rather than protruding out as it had on the Series I. A green plastic "gem" was located above of the headlight which would glow when the high beams were on. A kill switch and a covered lock were located at the back of the handlebars facing towards the rider. The horn and light switch was located on the right handlebar. The handlebar assembly was split, so that with the removal of two screws, the top cover could be removed for easy access to the cables and wiring inside.

On the rest of the body, the scooter was the same as the late Series I (non-frame breather). The 125cc models had aluminum strips for floor runners, and the 150cc scooters had rubber strips in aluminum channels. Badging was the same as on the Series I, with a long "art deco" style Lambretta badge on each side-panel, and a small Lambretta badge and model designation badge on the legshield. There was also an Innocenti shield in the center of the horncasting. A "dummy" air vent grill was located on the frame behind the rear seat. During the production run there were minor changes to the horncasting and the rear taillight lens.


As with the Series I Li, the Series II came in both 125 and 150cc trim. The motor design followed Innocenti's normal "evolution not revolution" philosophy. The power plant on the Series II was not substantially altered from that on the Series I LI. The cylinder and the piston were altered from the Series I version. Over the course of the production run there were several minor alterations to the carburetor and the generator. As on the late Series I machines, the air for the carburator was drawn through a small scoop under the front seat, as opposed to through the frame on the early Series I.

Bottom Line

The Series II bikes are heavy and relatively slow. Since motor power output was unchanged from the Series I machines, their performance is on par with the Series I. As with the Series I's, motor parts are generally easily available, while body parts can sometimes be hard to get.

The Series II LI's are extremely good looking scooters whose slow speed and generally poor lighting makes them less than ideal daily drivers. Still it is hard to beat a Series II for a Sunday cruise!
