JohnnyO - the rider was a C grader on an RM 400, as he recalls, he can't remember his name but said it was good and bad, reason being that once a C grader was clearing them then the A graders were looking at each other sayn "OH Shit" he also said the quads at Tivoli sent a heap of riders off to Hospital, very steep and big!
He was racing the day Stu died and said she was a big crash, also said that he and Stephen Gall commented a few years ago that Stu was one of the fastest and could have gone all the way (on a world stage) but wasn't fit and when the track cut up could be riden down, but was quite clear on how tough it was to stay with him.
Al had a ride with Moto Sport Yamaha on a YZ 250 G, then got offered a ride with Annan & Thompson on a YZ 465, he was on the 465 when he broke his back in 81.
