I had basically the same experience. I was looking at 3 bikes at a dealership together. A 2008 VFR800, a 2011 V-Strom 650 (outfitted for extreme touring, 20,000 miles on it including the Dalton highway), and a 2009 FZ6. I fully intended to buy the VFR800, I was riding the others just for comparison and to say that I had done my due diligence. These were not some lap around the parking lot excuse for a test ride either, they were about 10 miles on each of the bikes.
The VFR800 was ok, but the posture was more aggressive than I expected (since everyone called it the original sport touring bike, or the ultimate sport tourer). Also while the throttle was more responsive than the 1982 XJ650 I owned at the time, it was not as responsive as the FZ6. Overall I expected it to be alot better than it was.
The V-Strom was down right boring, and I was driven crazy by how jerky the throttle was as it engaged and disengaged. To be fair the boring nature of it may be from the mods, like I mentioned, this bike had ridden the dalton highway, so it was setup for extreme conditions.
The FZ6 was amazing, I immediately fell in love with it, the longer I was on it the more fun I had.
I will never buy a bike again without a test ride. Sooner or later you will find a bike you just never want to get off of. That is the bike for you. You can see from my profile which one I chose.
Side note: Ironically, my buddy who I am doing a massive multi-week ride with shortly just bought a V-Strom 650 himself, so I will get to try riding one more in the very near future. I am interested to see if it grows on me.
