Porsche designed the VRod motor, but I think they are made in Milwaukee. I could be wrong, but that hasn't happened since the late 70s.

In 1984, I toured the HD factory in York, where I was told that Porsche had developed an 800cc four cylinder for HD, but they didn't have the $12 million to put it in production. My point with the VRod is, the best motorcicle engine ever was put in a frame that is sub par to the industry. I love that motor, but the front end is raked too much for the trail and geometry of the rest of the frame. Like I mentioned in another thread, the old gangs are hanging on to the shovelheads that they cursed because of AMF engineering, but HD has some great motors now. I hate the Milwaukee Madness that accompanies the purchase of the HD line.
