Monash Motorsport's M11 car was a complete redesign of the previous concepts. The decision was made to move from the Honda CBR 600RR 4 cylinder engine to the KTM 450SX-F single cylinder, sacrificing power for a more fuel economic engine and in the process significantly reducing the weight. The Car also made full use of the new aerodynamic rules which allowed for the wings to be extended at the front and the rear.
