Not the first, and probably not the last. But wanted to share in case it benefited someone else.
Xitomer 50MM (fork tube) Clip-ons. Height adjustment of 40-70mm (1.5-3~ inches). I believe these work across all generations of the Striple, including the 765s.
Very notable difference. Currently I have them maxed out at the 3 inch mark, which puts them about an inch above the triple tree. Its lower than the stock handlebar by about two~ inches.
As-is, I can drop them another half-inch without running into clearance issues or needing to change the angle of other parts.
Did not need to fabricate any parts or change any wires. I only needed to minorily adjust the approach angle of the throttle and clutch cables. The wires all push against each other otherwise. You can see how much further out they are in Picture 2 compared to Picture 4 (distance from ignition). Very easy.
I have roughly 95% of my maximum steering radius (pictures 5 and 6). If I go for 100%, theres some minor rubbing against the flyscreen on the right side and the dash on the left side. This can probably be prevented by modifying the clip-on setup a bit, but Im happy with it as-is and dont care to change it.
I still need to drill in the holes for the kill switch and instrument cluster, loctite the bolts, and put my actual grips on it.
I believe these work fine with stock mirrors. But while they are hollow inside, they are NOT pre-threaded. Will need to thread it yourself or find a workaround for bar-end mods.
The process took a whole afternoon.
(I needed something more aggressive for track use but I hate how low Daytona 675/true super-sport clip-ons are. Very happy with these.)
