Hi Noel, no knobby tyres over 85cc/150cc is rear only, front is ok
once entered a championship class, your second, third, fourth classes are only $20.00 extra
If like a enquiry I had today, I entered in the xt/tt 500 support class it would cost $80.00 plus $20.00 for each extra support class I enter, not my $80.00 for the support class plus $20.00 per extra championship class, hope this helps
ACTMCC wish to advise also the championship class cost is expensive due to ambulance and permit costs for this event, the ambulance and paramedic costs for this event is 3 grand alone
