Floridians Mark Chin (No. 77) and Michael Barnes (No. 33), both on Yamaha OW01s, head a group of riders in the Mid-Ohio AMA Superbike event in August of 1990. I’m guessing this was a heat race based on the fact that Chin finished sixth in the first heat just ahead of Barnes in seventh. I’m not 100 percent sure who the riders are behind Chin and Barnes. I’m pretty certain No. 27 is Barry Burke, but I have no clue on No. 23. I believe that was Doug Polen’s number, but if I remember correctly, he was off racing in Japan, so perhaps the AMA reassigned the number to another rider. I’m going to take a wild guess and say that No. 23 might be Kevin Erion racing a Two Brothers Honda RC30. If it is I think that’s a pretty rare capture, because I don’t believe Erion raced in too many Superbike races. If anyone knows for sure who riders No. 27 and No. 23 are please leave a comment.
