That picture is from the holeshot site.
I am running stock 160's
I have not installed the hugger yet but from what I can see right now,
it looks like it can fit a 180. If you are willing to wait till saturday, I will post
it with several pics from several angles with a 160 and you can make your mind up.
THere might be some after amtket huggers that will fit a 180 tire. I have the suzuki hugger on my 05' and it barely fits. No way a 180 would fit under it. The 170 looks great though. The hugger is so close to teh tire, maybe a 1/16 of an inch of clearence. Keep in mind that your tire is going to expand a little bit when it gets hot.
