MOTO GUZZI V-twin development story

Preface
There's a rumor that the MOTO GUZZI big V-twin engine is a reuse of farm tractor. Some magazine or people repeats frequently this joke.
Look. Ride it seriously.
MOTO GUZZI bikes convey a message that they are not such a stupid design, and they have clear intention of their designer to do with.
Then, how was the truth ?
How was the designer's will that makes GUZZI bikes so special shape ?

"Trace of MOTO GUZZI V-Twin"
(Japanese)
That is an article of MOTO GUZZI owners club Japan.
This page is almost a reinforced revision of it with some new investigation and references. There're many duplications or repetitions, under an acceptance of MOTO GUZZI owners club of Japan. (Thanks to the tolerance of the club.)
This page has a same purpose with it, that is, to clarify the truth of the birth of GUZZI V-twin.

It would be a bit boring to describe a history as a list of technical term, so I've wrote these pages as a story on a historical background and a human affairs. You will find some new things, not a stupid jokes like above.

OK, let's begin a story of tremendous technical experts, it's a little too long though.
