Top box rack.

Anyone give some advice on the best place to purchase a rack for the genuine GIvi top box for a 2017 Multistrada, new or used, managed to get the box at a good price so just need the rack. Thanks in advance.

I think you have several options:

First of all I’d also post in the forum, as it’s specialised.
Pay through the nose via a dealer or a Givi retailer
Givi top boxes fit on a plate that can be bought separately and fitted to a rack that fits the bike
