LAMBRETTA MODEL 125-150 DL/GP HISTORY

Following the positive collaboration with Bertone on the Lambretta Lui, Innocenti decided to entrust the famous designer with renewing the lines of the LI Special series without, however, changing its basic structure. With just a few important modifications, the Lambretta became an elegant and modern scooter, while keeping its young and sporty look. Bertones new design of the bodywork fit in perfectly with the old frame, and helped update the overall performance of the scooter.

The most noticeable alteration is without a doubt the larger rectangular headlamp that looked similar to those used on several sport cars. Apart from that, the slimmer legshields now had a curious ink splotch, which was supposed to give an original touch to the new series.

Other changes to this new model were: the large saddle with sharper edges; the rear fender made totally out of plastic, and the black rather than gray molding.

Compared to the earlier version, the mechanical system was practically unchanged except for a slight adjustment to the low gears, which modestly increased the maximum speed. A new carburetor was added to the 150cc version with a diameter of 22mm, just like on the 200 DL.

With the revamped DL series, there were no longer any visual differences between the 125 and the 150 version except for the writing on the legshield and the different paint colors of white or turquoise for the 125 and red or white for the 150.

At the end of its run to keep production costs down, a few parts of the bodywork were made in plastic, and small safety balls were applied to the ends of the brake and clutch levers.

When construction of this model stopped in April 1971, Innocentis adventure into the magical world of two wheelers came to a close after fourteen stellar years of innumerable successes and immense satisfaction. The Lambretta DL would live on in India, where the government rebuilt the complete production line.
