I would definitely recommend bigger handler add, I used to have 6inch rise handlebars but found the riding position was a bit more unnatural so now use 5.5 which are still quite a bit higher than the normal.
I would also look at a triple clamp that you can adjust the position of the handlebars, moving them forward will give you more room. Other than that I’d definitely look at stiffer suspension springs front and back, if you’re tall you’re likely heavy and stiffing the suspension will make the bike ride better.
