Unfortunately much of it was a hoax. According to some sources she doesn't even ride a bike. She did take a bus tour and brought a motorcycle jacket and helmet to use in pictures. She didn't have any special access, and bikes are not allowed in the zone at all, nor are solo tourists, only escorted bus tours. It's too bad, she makes some good points and took some good pictures.
(I swear I'm not just following you around the board David, I ride a bike and this thing was all over the motorcycle forums I frequent a few years ago. We were all kind of pissed to find out she'd lied about it, takes away from the general sense of truth.)
