The Kit Kat was Italjet’s solution for people who enjoyed flying and boating but then found themselves at a destination without wheels for land. It weighed just 73 pounds, so you could even throw it in the trunk of your car if necessary.
It featured a 2.2 horsepower 49cc two-stroke engine paired with a 1-speed transmission through an automatic clutch. Check out this “personal-use report” from the Feb 1972 issue of Popular Science:
This example is said to be all original and in “excellent condition” though if you want more details you’ll have to ask the seller directly. Could make for a cool pit bike…
