Hiya well good luck and contact me if you need anything in Italy, I live in Roma and I have a van as well as a well equipped garage. I have loved my XT660X in trips around this country as well as the islands (Sicily, Sardenia, Elba and Corsica) and the engine is simple and fairly bulletproof. I have just ordered a set of Continental semi off road tyres (I think it is the Trail Attack) as I use the XT all year round so I intend to mount the Contis for the winter and then normal Pirelli road tyres for the warm summer. I have also mounted the excellent aluminium Givi cases which are great too. I would try each of the models or at least sit on them as the Z is a very tall beast I think. Good luck!!!
