This may read a little better since it posted a little weird:
17.14 AUSTRALIAN SUPERCROSS
CHAMPIONSHIP
17.14.1 Championship Classes
SX-Lites
2-STROKE - 100cc-150cc
4-STROKE - 200cc-250cc
SX-Open
2-STROKE - 156cc-250cc
4-STROKE -251cc to 450cc
Apparently (according to vitalmx) 250 2-strokes will be allowed in the 250F class in Aus MX and SX. I'll try to confirm this.
Hey Burn,
This looks like last years rules. This years new rules aren't written in that format. They are as follows :

- Australasian Supercross Championship SX - Lites - 250cc 2 stroke and 250cc 4 stroke
