About Vespa

Country of Origin: Italy
Founder: Piaggio (designed by Corradino D’Ascanio)
Best Known For: Steel-bodied step-through scooters; Primavera, GTS, and enduring lifestyle icon

Company History

Born from postwar necessity, Vespa made urban mobility elegant: monocoque steel bodies that shielded riders from grime, a step-through frame that welcomed any attire, and engines that started every morning. Over decades the brand balanced heritage with modernization—two-strokes to clean four-strokes, carburetors to EFI, drum brakes to ABS—all while preserving silhouette and social status. Vespa is as much culture as product: clubs, rides, and a design language that reads stylish in Rome or Bangkok. Practicality underpins the romance: under-seat storage, weather protection, and dealer networks that keep parts on hand. Today’s GTS still threads traffic with poise, proving that thoughtful design can outlast fads and that small wheels, done right, make cities feel human-sized.
