Sensation of the 1953 Milan show, the 300 twin was virtually a doubled-up version of the well-developed 150cc single. Although lacking in power, the B300 was exceptionally smooth, easy to start and very flexible. This was a luxury tourer from a company that mainly produced inexpensive lightweights that sold in the U.S. under the Sears & Roebuck label.

Ooops...forget that post. 380 lbs was probably in line with bikes of the 300cc displacement. I bought a 1966 Honda 305 brand-new, but forget what the weight was. A 300cc 2-stroke would have probably blown the Honda away on the street. But...the article mentions the bike as being shown at Milan in 1953 and that this particular bike was a 1956 model. I would have guessed that the bike was produced in the mid-sixties, not the mid-fifties.
380 lbs? Really? Wasn't that a bit heavy for a 125cc?
This Gilera at first glance has the profile of a 60s BSA twin. I wonder if also leaked oil and had questionable electrics like a BSA.
