Motorcycling Australia has changed the rules in relation to racing Junior 4 stroke motorcycles.
They have decided to not allow them to jump over man made jumps and will only allow the exhaust to be modified.
This means that a group of bikes can no longer be raced just when 4 stroke bikes are being seriously raced.
Send an email to Motorcycling Australia telling them that the new rules are wrong and should be changed now.
