The Givi MR5 style metal rack is a convenient and multipurpose luggage support bracket. Pair it together with a Z113C universal Baseplate adaptor to fit a Givi/Kappa or other aftermarket monokey/monolock luggage boxes, or use it standalone for utility carrying.
This steel luggage rack bolts up to the existing passenger grab bar mounts on your motorcycle, and replaces the passenger grab handle if any. Rated for 10kg but looks like it can carry much more. Fits Honda C100/Dream/Astrea/Citi/Wave/Supra/Biz 100 underbone mopeds.
