Wilkie was pushed all the way last season by Waitakere's Ethan Martens, while Taupo's former national TT champion Brad Groombridge also featured.
The two riders will likely be near the front at the Bike Torque-sponsored event this time around as well.
In the premier all-terrain vehicle (ATV) class, Canterbury's Ian Ffitch was the big winner last season. Although he was pushed all the way, a cool head under pressure gave the 43-year-old the advantage where it counted and he won the final race of the weekend to snatch the title ahead of Rotorua's Jason Jepson and Stratford's Camo Keegan.
Ffitch will be among the ATV favourites again this weekend.
Organised by the Taumarunui Motorcycle Club, the venue will be signposted from the Western Bay Rd turnoff, Kuratau Junction, SH41 and SH32.
