yeah well, I have the gpr and I run a lot of track day's at summit point WV and that's by far the bumpiest track I've ever been on, between 6 and 7 on the gpr and the bumps don't upset the bike as much but it also depends on what kind of day I'm having. On the street I just set it and go, I've never used it anything beyond 4-5 and it feels perfect.
