Porsche engineering designed it, not HD. HD paid for the NRE (Non-Recurring Engineering) big time. So, it's not really a H-D newly designed engine in the truest sense. Nothing original coming from Milwaukee in the realm of engines in many years, or frames, or many other critical areas. We blame it on the EPA for the strangled engines, but it's appearing like more and more, there is just not within the R&D capability at the Willie G. R&D center to do what is necessary to keep up with the times.

I stand corrected, at least 1/2 way. I can't comment on the NRE, can't find anything to back up nor counter that. This topic wasn't started to debate the existence of the Revolution motor. I enjoy my V-Rod that's why I own it. I would love nothing more then to have a garage with a Pan, Shovel, TC, or any variation of original HD standing next to my V-Rod. I do own a Harley-Davidson as far as I'm concerned. I wanted a bike made in this country which it is. Same as the Ford truck I own. I could have bought two bikes from Japan for what I paid for the SE but I wanted to try and keep my money in this country.

The 2002 V-Rod: Harley-Davidson's revolutionary muscle bike.

The look of the bike is hot, but the heart of the V-Rod (VRSCA in Harley code) is the Revolution. That's the name of the advanced liquid-cooled, 1130cc, 60° V-twin engine with port fuel injection. This double-overhead-camshaft mill has four-valve cylinder heads and was co-developed with Porsche Engineering (no joke). It's Harley's first liquid-cooled engine and belts out 115 hp at an un-Harleylike 8250 rpm. But true to the hog tradition, the Revolution makes a boatload of torque, a full 74 ft.-lb. of meat-melting muscle."

The Revolution engine is based off of 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 inches (1,130 cc), producing 115 horsepower at 8250rpm at the crank, with a redline of 9000rpm. [38] [39] It was introduced for the new V-Rod line in 2001 for the 2002 model year, starting with the single VRSCA (V-twin V-Twin Racing Street Custom) model. [40] [41]"
http://en.wikipedia.org/wiki/Harley-Davidson"…as far the co-operation of the two renowned manufacturers Harley Davidson and Porsche go, show the fact that the engine of the V-ROD in a venture project in Kansas city, Missouri. Harley Davidson holds by it 51 per cent of the being correct rights, Porsche for 49 per cent.
Basis of the joint undertaking is the co-operation of both companies continuous since beginning of the 70's-years; among other things Porsche brought the know-how for the building of the new factory in Kansas city, Missouri. Also the engines of the other Harley series were already optimized with of Porsche assistance both under performance and under sound and emission criteria."
http://www.dlhill.com/vrod.html"It has been no big secret that Harley has consulted with Porsche for nearly twenty years, first with the never-marketed Nova V-4 project in the '80s, then with the VR1000 Superbike project in the '90s. So when it came time to provide stallions for the new power cruiser, it was natural they'd seek Porsche again. The injection system hails from France, the ignition from Italy,
but a lot of the internal hard parts are German, such as the Mahle pistons, which have also been used since the Evolution Big Twin days of the mid '80s."
