I've put around 1300 on mine already, now I'm shopping for an exhaust. The akrapovic one is just too ridiculously priced. Leo Vince makes a nice dual setup for the 2007 SM 690 and I am wondering if it would work on the duke. They have the same engine, swingarm, and tail section. FMF is producing a slip-on for $899 but it hasnt been released yet, probly within a month or so.

I actually went down going through an intersection this past weekend, nice and slow, just slid out when I hit some shale. It scratched the handlebar end and a tiny tiny scratch on the tail section and thats it, I was surprised.
I set the map on setting 2 after the break in period and she seems much more responsive and torquey. I like 2 a lot better than 3 but havent tried any of the others. (why does the manual only describe 1-3??)
