2015 Rule Changes

2015 Rule Changes

Sep 24, 2014

The rule changes for the 2015 racing season  have been voted on by the clubs and here are the big changes for next year.

As of February 2015, 125 drivers will be allowed to use the new generation engines including the Leopard X30, PRD Galaxy and the current FR125 Rotax Max.  Current 125 drivers will however be allowed to modify the currently allowed motors with an optional carburettor and muffler, estimated to cost $350.00 for the upgrade.  This will make the older motors competitive with the new generation engines, not forcing drivers to have to update their engines to remain competitive.  Final revisions will be made over the next few months and the full rule released on the website soon.

The remote clubs such as Alice Springs and Weipa have been given additional practice meetings during the year (twelve instead of the current 4) and are also allowed to accept “non-qualified” drivers to race at their state titles.

Maximum kart weight in Junior Heavy, KT Medium, KT Heavy and 125 Heavy will now be performed before the race, with those failing the weight excluded from the race.

As from 2015 the Australian title plates will be Yellow Numbers on Green Plates.

Rookies will have the option of running full width plastic rear bumpers, the same style used by the current midget karts.

Appendix “D”, our track requirements has been totally revised with new standards being implemented in 2015 and 2016.

There are also a lot of other changes, some relating to procedures and some rewording of current rules.  The complete 2015 rule changes are listed below
