37th Annual Rimrock Grand Prix
October 2, 2016
Please pre-register - we'll have your stuff ready for you when you come to sign-up. We'll have a separate (much shorter) line for those who pre-register.
For the NMA Off-Road series race rules and a complete discussion of the race classes go to Class Descriptions.
Display your correct class designating letter on all three motorcycle number plates.
Important - Should any motorized user at any time take their vehicle in or through Tieton River or Indian Creek, they will be subject to a fine in the thousands of $$ and such activity will likely result in the loss of our event permit. As a community of motorized users, we must police our own!
