Some folks have injuries that make advice to "work out, and adapt" irrelevant. I am such a person.
I modified my ZX14 to be virtually as comfortable as a Concours 14. Just a lot faster and better handling.
I put Ulysses (Buell) pegs on, which is a 2" drop, and an LSL triple tree top clamp with normal bar clamps. On that I put a LSL/Spiegler riser blocks and then a Superbike High bar. Of course, I had to buy +7" hydraulics, throttle cables (push pull), and patch the wiring bundles going up on each side to the switch pods. So not a weekend project, for me at least.
The addition of Givi v35 side cases and a Givi top case gave me the luggage capacity I needed when going on multiday trips. Plus the hard side cases and top case cut through the air really well. I never noticed much air turbulence or resistance at all.
So you can turn your ZX14 into a true sport-touring machine, the question is, why? If you can answer that, do it.
I finally threw in the towel and switched to a Concours 14 because I have no interest in going fast in a straight line or on gentle sweepers any more. And the Connie will handle my mountain roads quite well. Tight stuff is more skill than bike, anyway.
