For what it's worth, I'm trying to attach a CAD file of my dogbones. I think they are an improvement on what is generally available, as no mods required and std, -50mm and -100mm easy to change by undoing just the lower bolt. No mods to frame and the lower fairing stays in place. Possible to play around with the 50mm and 100mm numbers a bit. Even possible to go higher as well if required, all without mods to the bike.
