The Triumph high mount works for me! I just bought longer bolts and thought I'd be good. Well the gf just came to town (she has her own bikes in Chicago) and was first pillion on my 955. She was less than comfortable because the right peg stuck out about 2" farther than the left.
So I went to work modding the mount. I cut about 3/4" off the the part of the mount that touches the frame and then ground some of the peg hanger and where it contacts the mount some to bring it all in closer. After testing that out (which helped a lot) she said the stock exhaust hanger was causing her discomfort so I Dremelled it off too. Near perfection achieved! Yay!
Brought the peg in closer to the pipe and the pipe in closer to the bike. Hey, greater "mass centralization" as a side bene! LOL
Rear view. FYI those are the front signals with Clear Alternatives lenses and their chrome bulbs.
I like a little fender for the wet so I just trimmed mine up a bit. Works for me! Good luck. Have fun! Mark H.
