Yes. The Harley Vrod had the 60 degree liquid cooled Revolution engine, which was a combined development between Harley and Porsche. It's a brilliant motor, but they only put it in the Vrod and didn't expand it's use across other models. The Vrod was a muscle cruiser, not very comfortable for long rides, not easy to add accessories like bags, etc., certainly not great for 2up riding and handling was relatively poor. I considered a Vrod and test rode a few before settling on a Rocket. I think the Harley traditionalists didn't want any part of it since it wasn't air cooled, not a 45 degree motor with the trademark potato potato potato sound.
