As has been stated, the 170/60-17 will work fine. I have this tire, and have actually moved the centerstand up further than stock for ground clearance, and only needed to grind a little off the side of the one of the feet. The stand had plenty of clearance before I moved it up. A 160/60-17 tire is even smaller in diameter than the 170, and would increase the revs slightly more than the 170/60 does.
