The 2021 BMW G 310 R is a small-displacement roadster with a 313 cc liquid-cooled single-cylinder engine.

BMW says accessories may be installed by a retailer or by customers themselves. A listing in the 2021 BMW Motorrad accessories catalog does not establish present availability or universal fitment. Before buying a rack, topcase or electrical accessory, verify the BMW part number, mounting pieces, model year and market. For a used motorcycle, distinguish original equipment from accessories fitted by a previous owner.
