First time poster...longtime lurker! If anyone is hesitating on switching to PR3's 190/55 my suggestion is to do it as soon as possible. Switched out the original Bridgestone's at 4500 miles and the bike is totally different. It feels 100-150 lbs lighter, no longer requires the strong counter steering it used to and is a joy to ride! Wish I had done it earlier. Just got back from the "Little Dragon" and had a blast.
