An alloy engine means less weight and consequently reduced fuel consumption. The intelligent engine design also saves weight.

The alloy crankcase is divided vertically, with the cylinders integrated into the crankcase. Forged connecting rods are used. For optimum durability, we’ve used forged aluminium pistons running in cylinders made from an aluminium/silicon alloy and cooled via individual oil-spray jets.

Integrating the camshaft bearing system fully into the cylinder heads has also saved weight. The subsequent low levels of engine friction and the efficient design of the oil supply system have helped to reduce fuel consumption even further.
