Yeah, the back story for how BSB pulled itself out of the doldrums (like racing is here) and into the premiere superbike series is a fascinating one! More successful than WSBK, by many measures. They are advantaged by having lots of different tracks within a short-ish drive of each other, but still, it's not the only reason for success. Think our taxi-racing, which does very very well, despite the tyranny of distance.
