Can't see the problem with speed, not dangerous unless used in the wrong place, or at the wrong time, all STs are made for sustained high speed anyway, my 1300 gets to an indicated 145 no problems, usually on the autobahns whilst on euro tours, frighting thing is you're still in the way of the mercs and bm's coming up behind!
Important thing is the vehicle is stable, back in the day when I was a bike cop, I could easily reach 135 with my trusty old Pan 1100, and that was covered in silly blue lights and full of kit, also the speedo was calibrated so it was correct
