Sorry, but Henry is not a source that I would rely on. Plenty of info on Harley Sites.Henry Cole
For example harley-davidsonforums
As for the WLA, I have always wondered how HD managed to get a v-twin the wrong way round 😜 (Guzzi owner....)
VFR800 - nice, but Honda also made the mistake of dropping the Pan (v across the frame). Spose that they are relying on the revamped Gold Wing - again nice, but expensive and losing some of the original Gold Wing appeal. I must be getting old.
PS - found a photo of HD's 180 degree v-twin across the frame - nice!
The WLA was far more successful.
