Another Polish motorcycle factory was the WSK (Wytwornia Sprzetu Komunikacyjnego, which translates as "Communications Equipment Factory", communications also includes transport in Polish), closed in the 1985 after the early strikes against the Communist regime. The strike in the WSK factory was the first in Poland, before the Gdansk strike, reported by the magazines of all the world. This factory produced essentially small-displacement bikes, 125 and 175 cc, with a classic two-strokes layout. Up (first and second pics), the WSK "175 Kobuz", years '80s model; the early versions of this bike were realized during the '60s. In the third pic, the "M-16" off-road model from the '70s. After the end of the motorcycle production, the WSK choosen the production of helicopters.
I was unable to Google up a badge with the flying wheel design as on the chip. Also, the dates may not be early enough. There is a possibility of a link between the design and motorcycles though.
There is also a race series for go-karts called Winning Series Karting, or something like that. However, it's also too recent. Karts do have tires, though [g].
