You cannot bring your own bike. You are required to use one of our 2009 CRF line of bike sizes 50cc thru 230cc. Clutch bikes start at 80cc. We also provide FOX safety apparel (boots, helmet, pants, jersey, knee and elbow guards, gloves, chest protector) and Scott goggles, but you can bring your own if you like. We will supply anything that is needed to fill in.
