Company History
Paton is a Milanese jewel box: a tiny workshop that lived for Grand Prix racing and still builds motorcycles like instruments. In the 1950s–60s, Paton’s green machines—born from the minds of Pattoni and Tonti—faced larger factories on tracks with hand-fabricated frames, elegant tanks, and engines coaxed to improbable speed. The company’s persistence through lean years became legend in the paddock; Paton tuned, welded, and raced on wit and craft. A modern chapter arrived with the S1 road-legal twin, essentially a homologated love letter to classic racing proportions and sound, but with present-day brakes, fueling, and reliability. Low volumes keep the work intimate: each bike is measured, aligned, and fettled by people who know what every bracket does at speed. Historically, Paton stands for Italy’s racing soul expressed at human scale—engineering that trusts geometry and lightness over marketing, and a silhouette that turns a Saturday ride into a memory.
