[edit]Revolution engine
The Revolution engine is based on the VR-1000 Superbike race program, developed by Harley-Davidson's Powertrain Engineering team and Porsche Engineering in Stuttgart, Germany. It is a liquid cooled, dual overhead cam, internally counterbalanced 60 degree V-twin engine with a displacement of 69 cubic inch (1,130 cc), producing 115 hp (86 kW) at 8,250 rpm at the crank, with a redline of 9,000 rpm.[88][89] It was introduced for the new V-Rod line in 2001 for the 2002 model year, starting with the single VRSCA (V-Twin Racing Street Custom) model.[90][91]
A 1,250 cc Screamin' Eagle version of the Revolution engine was made available for 2005 and 2006, and was present thereafter in a single production model from 2005 to 2007. In 2008, the 1,250 cc Revolution Engine became standard for the entire VRSC line. Harley-Davidson claims 123 hp (92 kW) at the crank for the 2008 VRSCAW model. The VRXSE Destroyer is equipped with a stroker (75 mm crank) Screamin' Eagle 79 cubic inch (1,300 cc) Revolution Engine, producing over 165 hp (123 kW).
