Prototypes


1972 M1

A design team is established, led by Soichiro Irimajiri, who headed up design of the five- and six-cylinder road racing engines of the 1960s.
The team develops the M1, a top-secret prototype designed to explore the outer limits of the Grand Touring concept.
The super-fast M1 features a liquid-cooled horizontally opposed six-cylinder engine with shaft drive,
features that surfaced in the Gold Wing line years later.
