In 1970 the 600M and 600V were launched, with handlebars on the M and a steering wheel on the V. The 600M and 600V were exactly the same as the 550M and 550V, their launch was simply a name change.

On the 20th January 1970, all Lambretta and Lambro Licensees, Concessionaires and importers were advised that the Lambro had received approval from the Italian Traffic Authorities of a 600kg working load and the name changed with immediate effect.

Lambro 550ML

Italian production Dates: March 1970 - December 1970
Chassis Prefix: 43-ML

The Lambro 550ML was produced for the shortest time of all of the standard production Lambro models. The 550ML was manufactured alongside the 500ML, 600V and 600M.

The 550ML appears to fit in the middle market, featuring handlebars and both a carrying capacity and back size larger than the 500ML but smaller than the 600M. It retains the round headlights of the 500ML design rather than the square headlights of the 600V/M.
