After Innocenti ceased production of Lambrettas in 1971, the Indian government bought the complete Milan production line with all presses, machines and tools as well as all trademark rights at the end of the year. Another part of the deal was that Italian technicians were also employed to help relocate the production equipment and set up the new factory. The foundation stone for the new production halls was laid by the then Indian Prime Minister Indira Gandhi.

A state-owned company under the name "Scooters India Limited" (SIL) in Lucknow in the Indian state of Uttar Pradesh then began producing Lambrettas both to supply its own population and, after a while, for export purposes. The Italians also trained the Indian staff at the new plant and passed on their expertise in the production of Lambrettas. Nevertheless, production only began in April 1975, with the scooters initially being built for the domestic market. By 1976, production was so modern (in Indian eyes) that vehicles were also built for export to Japan, the USA and Europe. For a long time, the SIL Lambrettas were the only models available worldwide.

The first scooter model to be produced was the "Vijay Deluxe / DL" (Vijay stands for "victory" and is thought to have been inspired by the war won against Pakistan in 1971). An improved version was later marketed under the name "Vijay Super GP 150". In the final years of production, the scooters were fitted with an electronic 12 V Ignition with modern Japanese CDI and improved suspension damping on the front wheel.

Production figures at SIL peaked in the 1980/81 financial year with around 35,000 scooters built. Only a few years later, however, the figures had fallen to around 4,500 units. As a result, SIL underwent a strategic reorientation in 1997, discontinuing two-wheeler production and concentrating on its three-wheeler division with the "Vikram" models, which seemed more important in the socio-economic environment of the time for the cost-effective transport of goods and passengers. This ended the 50-year era of building Lambretta scooters. Nevertheless, spare parts continue to be manufactured in India, which, along with several other parts manufacturers, help to keep Lambrettas on the road. Even complete GP 200 Engines, although of dubious quality, can be obtained from Indian sources, which also sell them to European and North American scooter shops.

A trademark dispute between the "Lambretta Consortium", consisting of Motom Electronics Group S.p.a. (MEG) and Clag International Ltd (CLAG) and Scooters India Limited over the use of the name "Lambretta" continues to this day[1][2].
