Welcome to the site/group!First post and all that...
Same thing...6’2. The front position feels less cramped for my long arms. As far as any impact on the bike, can’t really tell any difference honestly, but that’s only up to about 90mph straight passing on the highway. Thinking about raising the seat. I really don’t feel that closed up, so I may leave it alone.
Good things to consider, woodcraft has two types from what I saw. One that mounts in the original bar mounts that is specific for the duke and another that mounts on the fork tubes. I would imagine the ones on the bar mounts give more clearance.I've been contemplating clip-ons for the 790. I had a pair of adjustable Apex clip-ons for my Ninja 1000 (Z1000-SX I believe for those on the other side of the pond) and it was a great improvement over the bars if you're more accustomed to sport bike style ergos. They have tons of adjustability from angle to sweep and height. The height itself can be adjusted relatively quickly if you're going from regular traffic where you want to be a bit higher to the twisties where you want them dropped down.
The only thing you need to watch is clearance to any surrounding bodywork for bikes that aren't designed with a clip-on style bar. The 790's headlight turns with the bars so it's not as tricky as some, but clearance to the sides of the headlight shroud for example could run interference with the controls once mounted on the clip-ons.
Here's a comparison of the Apex clip-ons vs. stock bars on the Ninja 1000
