Automobile Products of India (API) began assembling Innocenti-built Lambretta scooters in India after independence in the 1950s beginning with 48 cc, Ld model, Li 1st series. They eventually acquired a licence to build the Li150 Series 2 model, which was sold under the Lambretta name until about 1976 and later on changed the name to Lamby for legal reasons. They also for sometime made and sold Lambretta TV 175 series under the name of Mac 175. Scooter India Ltd acquired the entire Innocenti Unit in 1972. API also built the trademark model [API-175] three-wheeler which was based on Innocenti's Lambro. API continued to build Lambretta-derived models until the 1990s but have been non-operational since 1993.
In 1972, Scooters India Ltd. (SIL) a state-run enterprise based in Lucknow, Uttar Pradesh, bought the entire Lambretta manufacturing and trademark rights. Former Innocenti employees were used to set up an Indian factory as all the manuals and machinery instructions were in Italian. The first scooter built was the Vijay Delux/DL, which was badged the Lambretta GP150 in export markets. This was later enhanced to become the Vijay Super. Further improvements were made in the final years of production by incorporating a contemporary Japanese CDI unit and an advanced front suspension. SIL also distributed complete knock downs that were assembled in different parts of India and sold as the Allwyn Pusphak, Falcon, and Kesri. These were of a lower quality than the SIL-produced models and sometimes incorporated significant styling changes.
SIL production seems to have peaked during the financial year 1980–81, with around 35,000 scooters being built. However, by 1987 this had dropped to around 4,500 units with production finally ceasing in 1997. As of 2011, SIL's production now centres on the Vikram 3-wheeler, powered by the Lambretta engine. SIL also produces limited spares for the GP/DL range of scooters.[5][6]
