Revolution engine
The Revolution engine is based on the VR-1000 Superbike race program, co-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.[105][106] 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.[107][108]
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 more than 165 hp (123 kW).
750cc and 500cc versions of the Revolution engine will be used in Harley Davidson's new Street line of light cruisers.[109] These motors, named the Revolution X, use a single overhead cam, screw and locknut valve adjustment, a single internal counterbalancer, and vertically split crankcases; all of these changes making it different from the original Revolution design.
