I've been adjusting the ergonomics on my bike for quite some time. It's been really interesting, and great fun! On top of that, I care a lot about how the bike looks. Honestly, I like looking at it, just as much as I enjoy riding it.
Anyhoo, I thought I'd share some observations (I finally have it where I want it due to the fact my Triumph Superbars arrived yesterday, after a 5 week back order, and some tom-foolery with the shipping!!).
I'll start by saying, I viewed the ergonomics as having to account for three riding styles: running around locally, highway day-trips, and twisties in the hills. I discovered I could optimise for two, but not three. I chose local, and highway (I like the twisties, but if that was my thing I would get a track bike, and do weekends at the MotoGP track down the road).
Aesthetically, the stock tall risers and narrow drag bars jarred me every time I came out of a shop and saw the bike sitting there. The riding position was great for short jaunts at low speeds, but on the highway, I had to lean forward so much, to counter the wind, that my head was almost past the mirrors! And, they put a lot of pressure on my shoulders (This significant for me as might right shoulder is a bit dodgy due to an old injury). The seat always seemed a bit 'meh' to me. I reckon it looked like it was designed by the same guy that designs seats for public transport - and, my tailbone suffered a great deal on a ride over 30 minutes.
I wanted to move back a bit on the seat, the handlebars to be lower and wider - and I discovered, if my legs are more extended, the weight of my legs helps to counter the head wind - and relieved my tailbone!
I started with new handlebars. These were 29" HD drag bars; a couple of inches wider than the stock bars, and with much less pull-back. See image below:
I made some aluminium spacers for risers - they were 40mm. The riding position was pretty good. My hands were wide, and lower; elbows out. But, I was always a little worried about using bolts that were 40mm longer than spec, at the same diameter.
As for the seat: one day, I had the seat off and thought "holy cow, that looks great". I straddled the bike and thought "right, I'm taking whatever I can outta the seat" (and moving the rectifier).
The pegs: I got a set of Ed.L's forward controls (4"). Took some getting used to, but now I love 'em.
This left one last piece of the puzzle. The handlebars were just a touch too straight. I had to keep my elbows out a lot to keep my wrists in good shape, this affected the handling. Someone on here, mentioned that they had Superbars, and that it looked similar to my setup. I researched it and ordered a set. They have about an inch more pullback than the HD bars, and I could ditch the spacers, and go back to the original, early-model clamps, and original spec bolts.
The setup is now perfect for me as far as handling goes, and I love how it looks.
As a side note, I learned tons from this forum and was the beneficiary of the generosity of Lancer (handlebar clamps) and MShipley (A stock seat I could hack into at will).
