Harley-Davidson shows off Penster leaning trike prototypes
Not surprisingly, the Penster makes use of a 45-degree air-cooled V-Twin for its propulsion, though details on exactly how the leaning mechanism works are still scant. These prototypes were hewn in 2006 and now reside in the Harley-Davidson museum. They stand out as an impressive piece of forward thinking from a company that holds steadfast to its traditions.
