I have 7 sets of Dunlop Racing KR133 Radials Sizes 115/70r17 & 95/70r17. They are brand new but 5 years old. They were stored in a dark climate controlled environment for their whole lives. They are not blued or glazed. Personally, I would practice on them. I sold the bike out of state and have no use for them. Free but you must pick them up locally and take all of the 7 sets as I am moving in a few weeks. They are located ten minutes from Road Atlanta in Buford, GA. Call or text me at (404) 368 3571
