I think the best option for you is to go in for a Pirelli sport Demon 110. Wet and dry grip is just amazing.You can touch foot pegs while cornering
It should be a straight fit with no issues. The other good option was Michellin M45, if you get it grab it, but i dont think you will. The other good option is dunlop geocruiser on older cbz, however keep it thrid in the preference listYou can easily remove the front mini cowl, that should not have any issues



(no 120/80 available in 18 but only in 17 inch rims
)
it is 100/90 18 and has a round curve shape so does not look wide at all.
