There are separate classes for 125cc, 250cc and open-class bikes, ranging in vintage from twin-shock spring suspension pre-1975 motorcycles through to the more modern water-cooled and linkage suspension bikes of 1986.
Top riders expected to enter include Taupo's Bill Doe, Wanganui's Mark Ellen, Taranaki's Steve Gallichan, Palmerston North's Tom Vandenburg, Wanganui's Danny Willemsen, Katikati's John Bouzaid, Auckland's Mark Wooding, Stratford's Stan Jones, New Plymouth's Niven Muir, Norsewood's Kevin Hermansen, Christchurch's Mark Meadows, Kapiti brothers Ian and Stuart Pike, and Tauranga's national champion Peter Ploen, to name a few.
Riders are able to discard their three worst results from the series, so just 12 of the 15 races will count, ensuring tight racing to the conclusion, set for Wanganui on March 10.
