How many track days to a set of supersport tires? Good question, and one that's impossible to answer accurately. This ZX-9R's Rennsports have had one track day already, and will be fine for most of the second day. Generally speaking, a heavy, powerful bike will eat a set of the softest tires in one day, while you might get two days out of the same tires on a 600. Let local wisdom be your guide. Some tracks are more abrasive than others, and there are other factors, including ambient temperature and the average speed around the course.
