With the exception of the KTM and Multistrada the rest of the large ADV tourers are so close that preference related to street/dirt bias, ergonomics, engine type, maintenance play a large role. I will also say that an hour test ride will not tell you enough to determine what your real preference is and unfortunately unless you find things that are really wrong for you you are SOL regarding a meaningful decision. I am just over 5k into my Tenere ownership and it took a 2k mile tour to decide that this bike rocks on rough dirt roads and is an outstanding tourer. The miles also told me that while nearly as quick my Multistrada is a far more exciting commuter. The initial deciding factor for me came down to the low maintenance requirements on the Yamaha, and my disdain for BMW/Triumph dealers. The nearest Guzzi is hundreds of miles away so that was not an option. I do miss the original Stelvio design, it had a definite appreciation of a part of the female anatomy.
