The Michelin tires were used for a couple road course races so the wear on them is on the side with very little wear on the middle. The only reason for selling them is I prefer Pirelli on the track. The "marbles" seen on the picture of the front tire will scrub off, they are just rubber pieces picked up when the tires were hot and sticky coming into the pits as I didnt ride the bike around before taking the tires off.
$100 for the set or $125 I will sell the tires as well as mount and balance them if you have the wheels off the bike.
