With three races on Saturday and two on Sunday, there was an attrition rate in Williamson's class as one contender fell and landed head first, being knocked out and losing four teeth, while another broke his arm coming off his bike.
After Chase Williamson finished fourth in the opening race, his father did a gear change, replacing the sprockets, to stop the bike being so top heavy. The boy then came third, second, third and second respectively in the remaining races to finish second overall in points behind Moir. "That finishes off a good year for him," Trent Williamson said of his son.
Chase was victorious at the MX championships in Wellington, Gold Coast (New Zealand), Wanganui and Manawatu.
Also from the Wanganui club, Jet Ashworth qualified to compete in the 9-11 years' 65cc class in Taranaki, but didn't finish in the top three, with the title being won by Hamilton's Nicholas Westgate.
