About MBK

Country of Origin: France (formerly Motobécane; later Yamaha-owned)
Founder: Motobécane (Charles Benoit & Abel Bardin); MBK Industrie under Yamaha
Best Known For: Mopeds (Mobylette) and later Yamaha-related scooters for Europe

Company History

As Motobécane, the company created the Mobylette—an icon of French mobility that carried generations to work and school. Financial restructuring and Yamaha involvement transformed the firm into MBK, which then produced modern scooters and small motorcycles closely related to Yamaha models but tailored for European tastes and regulations. The throughline is practicality: dependable engines, easy spares, and frames that endure city punishment. MBK kept French assembly know-how alive while aligning with Japanese quality systems, giving Europe a steady supply of credible, serviceable commuters. Historically, the brand bridges eras—from bicycle-adjacent mopeds to EFI, ABS-equipped scooters—embodying France’s affection for two-wheeled utility. A tidy Mobylette still evokes village lanes; an MBK scooter, the cadence of Paris commutes. Both tell a story of accessible independence made possible by thoughtful, durable engineering.
