I had .75" risers and heli-bars, and it's a big improvement in comfort.
It still wasn't enough for me, so I now have the LSL top clamp and Speigler handlebars(dirtbike style).
I have a Corbin and a Kontour seat, both are decent, but I'de still like to try a Russell Day Long seat.
I also had and hated the Suzuki gel seat, but seats are 100% a personal preference and you must try them yourself.
I have Vortex reasets too and I find them very comfortable adjusted up and back.
I actually just got home from a ride with a friend who has a stock gen2.
We traded bikes for a few miles. Wow! I had forgotten just how much of a difference those modifications made.
The two gen2's felt like two completely different bikes! I have a full dual Akrapovic exhaust that weighs a quarter of the stock exhaust. The weight of the stock mufflers can be felt while flicking side to side through curves.
My EBC extreme pro pads and ss brake lines are superior to the stock brakes too.
His stock tires felt as though they steered much slower than my Q2/Roadsmart combo.
Even though it gets expensive quick, it's amazing how much a few bolt ons can really improve an already great bike.
