- Pre-Millennium: 2 stroke. Dual disk break machines all displacements (A, B, C levels) bikes from 1978-1999
- Four Stoke (A,B,C levels) bikes up to 1999.
- Open Age: includes Retro, Pre-Millennium, and Four Stroke. open age classes: (A, B, C levels) bikes from 1978-1999
There is a little "Flexibility" in these classes, call it friendly LIKE DESIGN, no tech inspection, pay your money and ride, ie: a 2003 YZ 250 would disappear into the Pre Millennium class, unless you smoked everybody.
