Each specific mirror adapter is specially made for the corresponding motorcycle model to ensure the best possible fit on the handlebar, combining practicality and comfort without compromising the minimalist visual impact.

The BS831B adapter allows the fitting of both the End Mount Rizoma mirrors to handlebars with an inner diameter of between 21 and 23 mm using the expanders supplied with the kit.

Please note: mirror adaptors are sold individually, please purchase one adaptor per mirror.
