Guess I have the ratio calculated incorrectly, see below. I'll report back with the new number Thanks. Just so I'm clear you meant 117/335mm=35% right? Will do. As I have found there's a big difference in designing in theory and actually getting out there and putting a bunch of miles on to really decide what works. Because the suspension is so critical to everything else, it's not like footpegs that can get relocated easily. I really want to get this right the first time. As always, I'll give the +/- when I ride it. Spent an obscene amount of time drawing, measuring and drawing and remeasuring to get the frame mounts and crossbars mapped into my CAD program so that I can draw the suspension mounts to have them waterjet cut.
