The increased amount of air and fuel the engine can mix due to the larger diameter of intake valves is guaranteed by the new oval-sectioned throttle bodies, which compared to a 63.9 equivalent diameter as on the 1198 Testastretta Evoluzione has been increased to an incredible 67.5 mm. The throttle bodies are controlled by a full Ride-by-Wire system, each separate from the other and are fitted with 2 injectors each: the first is set below the throttle and feeds the engine in conditions of low load use, whereas the second is fitted above the throttle, is activated when the engine is given the command to unleash its maximum performance.
