LAMBRETTA LI 125 & LI150 MODEL INFORMATION:
The 'slim style' Li series three was the start of a long production run and almost all future large frame models were an evolution of the Li series 3. The Li 3, was a great sixties design, and a lot of the advertising for the scooter used sixties model and icon Jane Mansfield, either sitting or standing on the Li. The body and panel work itself was all new in design, slimmer and sleeker, than the series two it replaced. New headlight, horn cast, slimmer leg shields, panels, rear running boards all helped make the 'slim style' look, well slimmer! Twin single saddle seats were fitted as standard on these machines, although the single dual seat was available as an option should you wish. The new Series three models gained rear frame badges in holders rather then the earlier models fake grilles. These badges wore the model, either Li125 or Li150.
Under the panels technical details mostly stayed the same, although a number of minor changes were made cosmetically. A new carburettor, SH18, featured the float chamber built in under neath the carb instead of the earlier MA/MB side float chamber items. This carburettor gave not only increased miles per gallon, but also helped to increase the overall speed of the new Li. The bulbous kick start stop bulge was dropped from the S1/2 in favour of a more streamlined chain casing. Due to the slimness of the body and floor boards, a kick start pedal with less of a kink out was utilised. Carburettor hose, although retaining the looks of the earlier models did now not need to be as long to bridge the gap between the air box elbow and carburettor. The air box was also given a slight overhaul, slimmer and with a redesigned metal neck and air filter cartridge retaining system. A more boxy exhaust box, with seperate U bend up to the cylinder was fitted with replaced the box and seperate tail pipe & u bend on previous models. All UK models came with a battery which provided power for the parking lights, which was a legal requirement for UK vehicles at that time. The battery also provided power for the horn and stop light. All other markets received the same direct lighting system that was more common to the Lambretta. The front suspension was still the same Innocenti design with trailing links sat on buffers, but slightly differing in shape, and thinner. Rear suspension again remained the same coil damper unit combined as on previous models although the was now half an inch shorter. Braking received slight cosmetic changes, and remained drum front and rear. The locking tab washer on the rear hub now sat in a recess in the hub itself, which also gained an extra hole taking the total up to three to allow easier fixing of the locking ring. The rear hub was tightened to its torque setting of 150lbs but the choice of three holes for the locating screw made for easier fixing at the factory torque setting. With a production so long, in fact the longest of any model, many mid run production changes were made. Early Series 3 Li's used four pole stators which carried over from the second series, later models switched to the to six pole system which used more lighting coils to give better electrics. Gearbox ratios were changed on the 125 models to improve speed. With the changes of new and existing models that were made, so the Li models received them as well. In 1965 the chrome ring underneath the headset was deleted, the gap left by that being taken up by a deeper headset base casting.
