Open every Saturday and Sunday from 10am-5pm to all 85cc and up bikes only.


South Fork uses an open track format for all 85cc and up bikes (we do not split practices). We’ve discovered riders self-regulate track time and get to ride when and as much as they want. There’s actually fewer riders on the track at any given time during open track days than when we split classes.


Check back by 8am the morning of any practice to ensure we didn't close or delay opening
