CYLINDER HEAD

The DOHC cylinder head contains twin chain-driven camshafts and two spark plugs (one per cylinder). The camshafts are assembled, making them lighter than forged camshafts, while the cam profile has been developed to create an especially torquey engine. 1 mm larger intake and exhaust valves as well as reworked ports which have been flow optimized to maximize airflow also aid in delivering peak performance. A new balancer shaft in the cylinder head located between the camshafts matches the increased RPM and increased rotating mass, while a knock sensor has also been fitted to detect knocking combustions and allow for lower octane fuels – perfect for round the world travel.
