It’s a ~70lbs/30kg heavier bike with a 2inch/5cm longer wheelbase, and wider heavier tires compared to the zx4rr. All of those factors will lead to more steering effort. Not much can be done about that, it’s the physics of the bike you chose. They’re far more stable at higher speeds, less desirable in city traffic.

Assuming these are the limiting factors. Looks like you don’t even have mirrors, so the handle bars can be swapped to a shorter bar as well but this is just going to make steering even more difficult. I see you have crash pegs sticking out the side. Not much reason to shorten the above if those are the widest part.

You could put an aftermarket rearset on to adjust the foot peg position but they’re generally not cheap and part of the reason they’re positioned the way they are is so you can use your legs to keep you planted when you launch it. You’ll need to look for some that allow adjustment in the opposite direction from usual. Most move them further up and further back for track riding from oem positions.

One of the bikes I own is a 600 supersport and it wouldn’t be my first choice for a daily unless nearly your entire commute is highway speeds. Even mine can break every speed limit in the country in first gear.
