A friend of mine had the Matte Orange Street. I loved it. I was seriously thinking about buying one, but the Super Duke has all of the same riding characteristics, that I didn't see the point.
I prefer the Street Triple 675 over my 599. Power wise, it's down a little on the 919. You'll throw rocks at 919s after you spend some time on a ST 675.
The 675 Street Triple is light. Aprox 400 pounds, when you're low on fuel. It's narrow between the knees. Very comfortable. I could ride one all day, I think. It has all the goodies right out of the box: fat bar, good brakes, just quality through out. The valves are shim on bucket, no the maintainence is pretty much like your run of the mill jap bike. They sound like a tractor, as far as I'm concerned. That's not a deal breaker, the bike so good otherwise.
Buy it. If you don't like it, sell it to me cheap. I'd like get back out to Colorado any way. Or better yet, buy my 599, and I'll buy the Triumph.
