3.5 GPS Navigation
NORRA recommends all vehicles be equipped with a GPS that can display the event route such that competitors have the ability to comply with the official course, remain within the allowable course tolerance, pass though any virtual check points, and avoid any restricted areas. NORRA will provide the official course route in Lowrance .usr format. NORRA routes are not physically marked, however a route book is provided in addition to the GPS trail. It is the competitors responsibility to successfully navigate such that they follow the route and avoid penalties for non-compliance.
8.9 Category MRR450: 450cc Rally Raid Motorcycles
Any age motorcycle with a maximum displacement of 450cc.
But I see nothing that says road book and CAP heading only.
