"I cannot find this accessory for my bike anywhere, why don’t you make it for me?”

That could have been the beginning of the story, which in just over 10 years has transformed the two brothers’ passion and creativity into a Premium Brand of motorcycle accessories and design products, made of exclusive quality materials, such as aluminum and composite fibres. 

Over the years, Fabio and Fabrizio Rigolio (General Manager and CEO of Rizoma) have managed to build up a young and dynamic team able to manufacture, and trade worldwide, the parts which impress everyone with their elegant and original design and with their maniacal quality.

The unmistakable style of Rizoma is summarized in the pure lines of its products, which give the object an elegant and refined minimalism. Also at the Italian Headquarters (located in Milan area), special attention is paid to the appearance, which is characteristic of a showroom: details are very important for a constantly evolving “Made in Italy” brand.
