In preparation for the 2015 Yamaha Australian Jetcross Championships, please refer to the rider classifications allowed for each racing class. You will remember that the AJSBA recently aligned our rider classifications with those of the IJSBA and a breakdown of the classifications can be found on the 2014-15 AJSBA membership form. If you are unsure which IJSBA classification you fall in to or wish to be reclassified please contact as soon as possible.
