Special Rules for 400cc 4 stroke Multi Cylinder

As the 400cc class is recognised and raced at national level in both MRRDA and Formula Xtreme, it is important that the TMCCRR rules reflect this. We have opted to use the MRRDA Pro 400 Class rules to govern bikes in local and Qld competition to be as inclusive as possible
