Vespa acquired popularity beyond Europe and North America. When looking to expand into markets outside of Europe and North America, it was common for Vespa to partner with, or license certain models to already existing manufacturers. Though the motorcycle industry has been and still is dominated by Japanese companies, Vespa still has a small but significant markets. While details are sometimes hard to come by, especially in some markets, some information is known.

India

Piaggio first licensed the production of Vespa scooters in India to Bajaj Auto in the 1960s. In 1971, Piaggio's license was not renewed as a part of Indira Gandhi's privatization programs. After the collaboration ended, Bajaj continued to produce scooters of its own design, namely the Chetak, using design and engineering cues it had gleaned from the earlier affiliation.

Another Vespa partner in India was that of LML Motors. Beginning as a joint-venture with Piaggio in 1983, LML, in addition to being a large parts supplier for Piaggio, produced the P-Series scooters for the Indian market. In 1999, after protracted dispute with Piaggio, LML bought back Piaggio's stake in the company and the partnership ceased. LML continues to produce (and also exports) the P-Series variant known as the Stella in the U.S. market and by other names in different markets.

Piaggio, in 2007, announced plans to reenter the Indian market. This time, however, Piaggio plans to do so with a wholly owned subsidiary.

Taiwan

Vespa has had various partnerships and presence in Taiwan. In 1965 Taiwan Vespa Co. Ltd was licensed for Vespa scooter production. From 1972 to 1982 Vespa entered into a collaboration with manufacturer PGO. In 1978 Vespa entered into a collaboration with TGB, which to some extent, continues to this day (namely with CVT transmission production).

Indonesia

A company known as Dan Motors Vespa produced Vespas under license for the Indonesian market.

Export of restored classics

The resurgence in interest in vintage motor scooters has also spawned the scooter restoration industry, with many restored Vespas being exported from Thailand, Vietnam and Indonesia to the rest of the world.

Much as Vespa had used the Cushman Army scooter as inspiration for its original design, Vespa in turn made scooters for Sears and Cushman after World War II.

Imported by Morton Colby of Colby General Tire Company, 662 E. Fordham Road, Bronx, New York, the Sears models were 3- and 4-speed 125 cc Vespas rebadged as Sears Allstate Cruiseaires. Innocenti also distributed their Lambretta brand via Montgomery Ward's catalogue during this post-WWII period. These were the premier brands of scooters, bringing premium pricing to many, including farmers, whose link to the outside world was via purchases made in these catalogues. Cushman sold rebadged Vespa scooters as Cushmans, but many Cushman dealers refused to market a "foreign" machine. However, collectors prize the Cushman Vespa because it is relatively rare.

Bankruptcy of Vespa's American importer due to two expensive product-liability lawsuits, increased competition from Japanese manufacturers, and certain states' passing so-called "green laws" caused a withdrawal from the US market in late 1981.

During 1981-2001, despite an absence of United States domestic sales, Vespas continued to have a core group of enthusiasts who kept vintage scooters on the road by rebuilding, restoring, and adding performance-enhancing engine parts as the stock parts would wear out.

Vespa returned to the US market in 2001 with a new, more modern style ET series, in 50 cc two and four stroke, and 150 cc four-stroke. According to the Motorcycle Industry Council, U.S. scooter sales increased fivefold over six years, swelling from 12,000 units in 1997 to 69,000 units in 2002. Vespa sales in the U.S. increased 27 percent between 2001 and 2002. The 65 "Vespa Boutiques" scattered throughout the U.S. gave scooterists a place to buy, service, and customize Vespa scooters, and outfit themselves in everything from Vespa watches and helmets to Vespa jackets, T-shirts, and sunglasses. Vespa restarted its American sales effort, opening its first boutique on Ventura Boulevard in Sherman Oaks, Calif.

In light of vastly-increasing US sales, Vespa developed the GT, offered as a 200 cc four-stroke and a 125 cc variant in Europe. In 2004 Vespa reintroduced a modernized PX 150 to the US. In the fall of 2005, Piaggio offered their largest-selling Vespa scooter ever, the 250 cc-engined GTS250, available in Europe with ABS.

Europe

Vespa's largest market by all measures globally is still Italy, but as a result of the mod subculture that developed in the 1960s, the United Kingdom is still Vespa's second largest global market—and at one point in the 1960s, its largest. The appeal of the Vespa to the style-conscious mods was the weather protection. Their counterparts, the rockers rode classic British motorcycles such as Triumph Bonneville and BSAs, and needed to wear leathers against the elements. Mods would modify their Vespas, adding lights, mascots, accessories, various racks and crash bars. A new lifestyle evolved in the UK, with thousands attending scooter rallies.

The dominance of the Vespa declined through the 1970s, as small car ownership increased and cheap and reliable commuter bikes like the Honda Super Cub hit sales. Despite the introduction of the more modern 'P' range in the 1970s, the lack of development cost Vespa, and like other markets, the sales fell off drastically in the economic boom of the 1980s. Then Vespa introduced the trendy automatic ET2, London introduced the congestion charge and—partly with celebrity chef Jamie Oliver's indirect help from his BBC2 series—sales suddenly leapt.
