MASH, a successful brand throughout Europe! The brand is a tribute to all great designs from the late sixties and early seventies. The models are built with great care and although they seem to come out of a different era they are completely contemporary! MASH is a manner of driving, MASH is an experience! MASH Motors is part of the French SIMA. SIMA stands for Société d’Importation de Moto et Accessories and is actively importing major motorcycle brands, parts and accessories since 1976.
