Givi will not fit straight on to the OEM Suzuki rails.
but...
you can make it fit
I made Givi panniers fit with my OEM rails easily- am planing on doing the same for the topbox when funds and time allow.
you need to remove all the mushroom lugs from the rails, and the locking tab.
(is a bastard as the bolts are made of cheese and the latch bolts are Locktited in- mash them you won't need them again)
replace the latch tabs with the givi ones - one hole will need to be drilled for each but I used one of the holes the suzki bolts went through.
you'll need givi boxes to figure out where the holes need to be drilled for the Givi version of the mushroom lug things.
one of these I think will give you all the parts, can't see if the mushroom lugs are included in the pic, but a givi dealer would know what they're called.

)
NB. do not buy V35's they will not fit in any way, shape or form with the OEM racks. Only Standard Monokey fit boxes.
the rails when I first got the things from a bloke in london. (silver- have striped the rust off and painted)
and after fitting Givi mounting hardware and boxes
