These Givi PLO1171MK Pannier Holders Honda CB500X 2019 on models are designed to accept traditional Givi Monokey Panniers and can only be fitted in combination with the Givi 1121FZ Monorack Arms (allowing a top box to be fitted) or by using a Givi 1121KIT if they are to be fitted on their own (i.e. no top box). The Givi PLO1171MK is part of the latest generation of Givi Pannier Holders called PL-ONE-FIT which is made from a motorcycle specific base pannier holder kit called a Givi PLO1171N (specific to the Honda CB500X, 2019 models and onward) fitted with a Givi OFMK Kit which enables the pannier holders to be converted into Givi Monokey Pannier Holders. By removing the OFMK Kit these pannier holders can be left blank to enable more traditional throw over or soft panniers to be fitted or converted using a Givi OFCAM Monokey CAM-SIDE Kit which will enable a variety of Givi Trekker Outback Panniers to be fitted. For greater rigidity, wear resistance and rigidity the Givi PLO, PL ONE-FIT, system is made from 18 mm steel compared to its predecessor which was 16 mm.
