Twelve-year-old Pietermaritzburg school boy Dirco van der Westhuizen's magical ride in the MX85 division of the Full Throttle South African MotoX Championships continued uninterrupted in round five in East London on Saturday.

Back-to-back victories in the day's two races and two fastest laps on his Bridgestone-sponsored Yamaha YZ85 underlined the Gert Maritz Primary School pupil's dominance of the junior class for riders aged between eight and 12.

Second, 14 seconds in arrears in the first six-lap race, was Northern Regions' Marcus Phelps (Kawasaki) followed by Eastern Province rider Bevin Potgieter (KTM). Van der Westhuizen had to overcome a slow start that saw him drop to fifth into the first corner, but he was already in the lead by the end of the first lap.

He was again denied the hole shot in race two, falling back to third at the first corner, but recovered to lead each of the seven laps and finish 11 seconds ahead of Potgieter. Northern Regions' Justin Thompson (Yamaha) was third.

After five rounds of the championships the Maritzburg youngster has racked up a formidable score of 245 points out of a possible 250, with nine wins in 10 races. A broken rear shock absorber in the opening race of round four in Bloemfontein ended a run of six successive victories. Second in the points standings is Phelps with 207, while Thompson and Northern Regions' Dean Godfrey are joint third with 185.

Van der Westhuizen's busy weekend also saw him campaign in the Pro Mini category (for riders aged between 11 and 15) on his Bridgestone Yamaha, where he once again more than held his own against the bigger and older riders. Despite first lap incidents in both races which dropped him to 15th and 11th respectively, he showed great character in fighting back to take a fifth and a sixth in the two heats behind double winner and championship leader Tristan Purdon (Honda) from the Eastern Cape.

As a result he retains his impressive fourth place overall in the class, behind Purdon, Northern Regions' Zane Farquharson and fellow KwaZulu-Natalian Bradley Cox, winner of last year's MX85 class (in which Van der Westhuizen was runner-up).

The next round of the championship is in Krugersdorp in Gauteng on September 24.
