Could someone here post any info on this, such as class champions, tracks, results etc.? I vaguely recall a late '80s rider called Wlodzimierz (?) Kwas racing at a street course in the city of Stalowa Wola (?) and a '70s rider called Pawel (?) Mankiewicz battling for the lead with a Hungarian (?) rider called Doppel (?) somewhere... I was a little kid when I saw TV footage of these events, so I don't remember much.
Please help me get rid of some of those question marks ;)
