I've recently replaced the rad on my Hyperstrada as the original sprang a leak which was repaired, but it then failed close bt after a couple of years. Rather than pay the £450 for an Ducati replacement I got a new one on ebay from a company called Tarazon ([email protected]) for £168 which seems to work well. You need to get slightly longer fan mounting bolts and larger bolts for the side covers/ rad grille if you have one, but very little extra.
