Worked on my old R6 at those sizes, cant be sure with NSR swingarm clearences or sproket offsets though,

Why do it? it will just slow flickabiliaty down, biggest you want it is 165 slick 160 dot. if its for street cred try a 170 at most. Just means your chicken strips will be even bigger when you turn up at chip shop
