Under the development name “Revolution Engine”, in 2002 development partner Porsche Engineering developed a new V2 engine for the “V-Rod” model of the American motorcycle manufacturer Harley-Davidson.Against the backdrop of a collaboration stretching back to the 1970s, the Porsche engineers constructed a water-cooled 1,131 cc motor based on a racing engine that delighted Harley-Davidson’s demanding clientele both for its performance as well as its imposing sound. With a DOHC valvetrain and electronically controlled fuel injection, the VRSC-series Harley with its four-valve engine put out up to 120 hp.
