In each of the two races at Manfield Dibben was beating Hart ( Yamaha YZF450) by up to 9 seconds with fellow Whanganui rider Aiden Brown in third. The trio finished 1,2,3 in that order in both races.
Dibben goes into the final round at the Cemetery Circuit on Boxing Day with 101 points, while Hart has 88 and Brown 76.
While he has a handy series lead, Dibben knows full well he can be caught, especially if he backs off the throttle or has a DFN (did not finish).
"I won't be doing that if I can help it," Dibben said.
It will handlebars down and catch him if you can, that's Dibben's style and what spectators expect of the Keown Honda motorcycle mechanic on his home track.
"The Whanganui street circuit is my favourite track and going to the front is the way I like to race. The old bike is still going well and I don't have any sticking plasters on it despite its age. I've raced this same machine for the past four seasons."
The Dowman Contracting, Tyre Shield-sponsored rider is not counting his chickens, but astute judges are backing the hometown racer to make it a clean sweep on Boxing Day before he heads to the street circuits at Nelson on January 2 and Paeroa in February where he has won the last two years running, breaking his own lap record last season.
