I just happened to stop at the dealer in Sturgis S.D. and to my surprise they had a blue S-10 on the floor. This bike, it seems, is only there on a temporary basis. Too much snow to ride, but got to listen to it run. I was really surprised to note that it's exhaust note is not bad at all. I have a raven on order, and need to sell a couple of bikes to make room for it. At least now, I think I will be keeping the stock exhaust, and freeing up money for other farkles.
