Is this the first attempt at getting power via extreme rpm and I mean not high but overboard, in 1955? Details Marvellously mechanical.

Well, while we're on the topic of unusual motorcycles...

How about a turbo-diesel with a twin-crank, twin-rod per cylinder arrangement?

I know it's utterly pointless, but that's why I like it so much.

This is just me talking, I have no special info, but I have always been very skeptical of the official power claims made for the Guzzi V8. Despite the high complexity and component count for a motorcycle of that era, the engine itself is not terribly sophisticated in its design. And it was unreliable and inconsistent in its performance. (Eight 20mm Dellortos? Hoo boy.) The whole thing strongly suggests to me that the engine was probably eating itself up in FHP. Again, that is just my take looking from the outside in, and almost 50 years later to boot. I could be totally wrong.

This is something that for sure has been around here, but on the subject of insane packing, a 100cc B12

I do agree that at that time DOHC's and individual intake was already around but the thing is, this engine has been specifically designed and engineered to rev, unlike most engines at that time where their targets to making power around a performance race bike were different. They did not use a vee eight configuration for anything else but to scream. As if those engineers in 1955 would be more surprised with the DFV than todays Formula 1 engines.

As radical as Honda launching the oval piston NR series.

Give it some wings (downforce) and you could ride it inverted. How beautifully pointless is that!
