Ironically, Hart had allegedly fallen and remounted at Hampton Downs last year, but had not been reported or charged with an infringement. By the time the allegation had come to light, the time frame for protesting had elapsed.
This season Dibben has been unbeatable, winning with maximum points at Hampton Downs and again at Manfeild last weekend.
"I could play its safe with the points I've got and just make sure I finish, but I don't want to race like a nana," Dibben said yesterday. "I'll be out to win both races and, in fact, I'd really like to take Toby Summer's lap record of 50.962 seconds. I nearly got it last year when I clocked 51.024s. The bike is going really well and apart from a few gearing changes and suspension adjustments on the day, there's nothing to do but get on and ride."
