Yes it is an OEM Kawasaki (made by Givi) for the V35 bags and it will fit on any Mk2 V650.
The V650 Mk1 & Mk2 was designed by Kawasaki to be officially fitted with Side Bags OR
a Top Box only
, so there was no OEM frames that fitted both together.
However, both Givi and SW Motech, both produced rear topbox racks, to be fitted to bikes with OEM luggage/side carriers
and also luggage/Side Carriers to be fitter to bikes with OEM approved rear topbox rack.
