Best weather protection, handling, comfort/ergos, mileage and range. That makes the Honda ST1300 the winner in my book. The ST1300 seems to be downgraded for nothing more than it's weight. Having toured for 10 years on a VFR800 and fearing for my life more than once in the seemingly ever present cross winds of eastern Washington state, I much prefer the stability that the weight of my ST1300 gives me now. I also use GIVI's largest top case and haven't had any stability issues with the ST1300.
