The senior equivalent of Junior Max, with a very powerful 125cc TAG engine. This is the biggest class to run at club level and always fields large grids. The engine is high revving but is limited electronically and this means lower maintenance. The engines are sealed to prevent unapproved tuning. Like many classes there is a higher weight variant called Rotax 177 for the heavier driver.
