This rear Bridgestone was made eight years ago, it has 4 days of racing on my SV650. The front has eight days of racing. Saturday with AFM at Buttonwillow was the final day for both of them. I did practice and four races with three podiums. I replaced the front with one that was made 14 years ago and a new rear. On Sunday with AHRMA I did practice and three races with two podiums. I don’t normally use tires that are this old but they were stored well and the price was right.
