ehh I wouldn't go with SPEED unless there was absolutely no other way to see the races... I'm not sure if they stream live from the WSBK site or if they're only up after each race or what... but Racing-underground.com has the races as soon as they're done pretty much...
but yeah I remember year before last (when I was back in the states) catch'n WSBK on speed once or twice on some odd tuesday or so... at like 3 am
