My old mate Luigi showed me this picture of his dad back in the day doing a mono and asked if I knew what sort of bike it was.
I wouldn't have guessed it.
Anyone care to guess?

Looks like a Bennelli to me?

No.
Nopety nope.

Munch Mammoth ... very interesting bike. Supercharged?

Yes it is a Munch Mammoth, well done. Blowed if I'd ever heard of em before. Dunno about supercharging though.
