SOME time ago, a number of design patent drawings Harley-Davidson three-wheel models in circulation. Apparently they have made several prototypes with Penster code. Three-wheeled vehicle was designed by John Buttera.
Although there is an awkwardness of the design that created the legendary custom car builder, but still it looks pretty Buttera creations. But for reasons that are unclear, this unique vehicle has never had a green light for production.
