Not very often, although the season just gone two Superbike riders came off there. One, Leon Camier, injured himself pretty badly and the TV replays of his leg bending in the wrong direction were not nice! It's only the riders who are confident that grab air like that. A lot of them shut off halfway up and then open the power again as they crest the top. Strangely there doesn't seem to be much time difference in the approaches.
