You don't see the bikes steering "around" the headstock anymore or weaving in a straight line - watching some of the older proddy based bikes coming down past the pits in a straightish line was scary enough and you used to see bikes getting well and truly out of shape anywhere that required a high speed change of direction, these days the bike will respond positively to big pull/push on the bars and standing on the pegs - just look at JMcG's nearly straight clip-ons, he's properly getting hold of the bike, DJ was very much the same but you didn't see the bike complaining too much. As mentioned by myself and others the course has been altered but it hasn't been altered to make a bike lap faster just to help/aid public use, if you look at Hillberry the dip is still there on the apex and I can't see any other advantages other than maybe a constant surface right up to the hedge - that never used to bother Brian Morrison through there though - every single lap the bike properly right over and out to the white line and more, I would like to know though why they held high speed closed road testing - I don't recall that happening anywhere else, maybe it's an insurance or liability issue ?.
