The dented area is not for the swingarm, but for the footpeg bracket assy. All you had to do with the "old" unit was to space it out on the bottom bolt with a 1/8 spacer and it fits fine. I still question the clearance between the 'arm and pipe though...it still looks tight. See my v under the members gallery................IMG_0992, page 6.I see that akrapovic has finally introduced a slip-on exhaust that's model specific for the versys. It has an indent for the swingarm that the ninja/er-6 one didn't have for clearance issues.
Directly from their site:that thing has to be as heavy as a stock can .:forgetit:
