Are you sure - that's awesomely light!? (unless it's the 125/160cc version.
)
[Edit2]
I get it - you don't use petrol, you fill the tank with gas - helium! 
Don't tell anyone, I've got the super rare 790cc single cylinder version that was built in Japan.
Most Wild Guzzi types have never seen one!!! So many will claim the bike does not exist!!

Giacomo Agostini and I only built a limited number!
Don't forget, helium in the seat and both tires as well.....
