I've removed a topbox from my scoot and want to put it on my first "proper" bike, a Kawasaki ER5. The box is made by Spada. Everywhere I ring want's me to have a Givi mounting plate fitted, and now I'm starting to see websites that suggest that spada and givi are one and the same - is this right? I'm told that a renntec rack at £60-odd would take the topbox, although websites that sell it say it won't, and a "proper" rack for my topbox will be around £80-£100. Are Spada and Givi the same? If so, then my Spada topbox will fit onto a Givi plate? Can someone also explain "monolock" and "monokey" to me? Thanks Jon
