I'm betting 90% of Team Gixxer would disagree with you. And don't you own a Concours?
You are grouping the skilled track guys who have taken the time to elevate their skills beyond public roads who happen to have a sport touring bike in the garage with the sport touring community in general.
And I'll bet you that 100% of the team gixxer crew will tell you they aren't even close to hanging out with the fast crowd but they are far advanced over the street guys. I would also bet you that any one of the team gixxer members would by choice ride slower than you if you invited them on a street ride. Not because they are incapable, it's because they are in an uncontrolled environment and they are wise!
