I just got a set of Rox handle bar risers for my 990 Adv. They are the "low pro" - 1 3/4" rise, pivoting model. The ones that the web site says are "the recomended riser for the KTM Adv". The problem is that the clamping area, once installed in the stock clamps, is 3/4 of an inch wider than where the stock clamps bite the bars (3/8ths on each side). They are so wide, that they are clamping down on the bar where it is starting it's upward bend. At that point, the bar is actually a bit wider than it is in the straight section, so the bar does not sit down all the way in the bottom part of the clamp. I could just crank down on the Rox clamping bolts and get it tight, but it would be deforming the clamps and gouging the bars to do so. Or I could get out the grinder and take the "corners" off the new clamps or grind the outer, flairing portion off of the stock clamps so the risers can slide in more. I don't really want to start hacking away at anything. Have any of you guys installed these and found that they clamp on the curved part of the bar?
