I own a Moto Guzzi Norge 1200. It is slower than most (all) of the other Sport Touring bikes, but it is comfortable, works well at speed and does all I could want. With removable hard bags that become suitcases, this bike fits everything that I was looking for. Seat height was some of the factor when deciding, and between the Yamaha, Honda, and Kawasaki, none of them worked for me. Just sitting on them at the showroom told me they would not work for my short 29" legs.
I like the character of the V twin coupled with the upright riding position. Maybe someday I will ride a cruiser, maybe not. I don't want ultra fast. I am comfortable at 70-75mph if I am on the freeway. I am not looking to get tickets so having a bike that is enjoyable to ride at legal speeds works for me.
