I have mounted the GIVI crash bars on my xt 660 z and have been very happy with the produt. Only problem is that it does not fit together with the Yam engine guard. I gusse I will need to do some metal fabrication and welding to have both of them on. As I hardly reach the ground and have made a fool of myself at least once I feel that the more protection the bike has when I am near it the better.
