Rule on Ride Up an Era:
Riders are permitted to ride their bike up AS MANY ERAs as you choose! With it being a 2-day event and with many travellers we want you to be able to have as many races as you can handle with what you bring.
The Normal Rules for NZVMX = A pre-70 bike may be ridden in the Pre-75 class (but not the Evo Class). A Pre 75 bike may be ridden in the Evo Class (but not the Pre 86 class). An Evo Bike may be ridden in the Pre 86 Class and so on.........
