About Sherco

Country of Origin: France (with Spanish facilities)
Founder: Marc Teissier & Andreu Codina
Best Known For: Trials excellence and competitive enduro/off-road motorcycles

Company History

Born from trials expertise, Sherco expanded into enduro with potent, sharp-handling two- and four-strokes that earn results in world championships and weekend races alike. The brand’s DNA is control—precise throttle response, chassis balance, and gearing that finds traction where others spin. Trials roots show in ergonomics and weight distribution that reward finesse, while modern electronics and suspension choices deliver stability at rally speeds. Factory and satellite teams feed setup knowledge directly into production, and owner communities benefit from parts availability and documentation that make home maintenance feasible. Historically, Sherco is a modern European success story: small enough to be agile, serious enough to win, and focused on riders who value feel as much as figures.
