End of the track for Motocross King

Shayne King may have ridden his way to his last double national title.
The 35-year-old former world champion came away with both the 250cc and 500cc national titles at the Ssangyong-sponsored event in Rotorua yesterday and then hinted it wouldn't happen again.
"This championship possibly could be my last in this country - I'm definitely not going to do two classes again," the New Plymouth-based rider told the Daily Post.
King led both classes going into yesterday's final round of the series and had little trouble completing the double on the Rotorua Motorcycle Club's Suzuki Motocross Track near Horohoro.
The Blue Wing Honda team rider picked up two wins and a third in the 250cc motos and clean swept the 500cc class on the way to his 24th and 25th national motocross titles that sit beside his nine supercross triumphs and world crown.
While his national aspirations appear to be gearing down King said he'd ride the Australian series in 2006.
He comes from the well-known New Zealand biking family and started riding as a three-year-old.
"My life, our life has been motorcycling. You have your ups and downs and the ups make up for it - it's a great sport and I really enjoy the fun side," he said.
He won his first motocross national title as a 16-year-old in Auckland but said yesterday's victories would overtake that as a highlight.
Part of his satisfaction was attributed to the demanding 2.2km track in Rotorua.
"This is fantastic - actually the track is the most physically and mentally demanding circuit at this year's nationals," he said.
"The club did a fantastic job to keep it prepared ... it's one thing to have a good track, it's another to make it rideable."
After 19 years of national and international competition King is in a good position to gauge the strength of New Zealand motocross. He also sponsors many through his Crown Kiwi Enterprise business.
King believes there's plenty of potential in the country's young riders but warned it takes more than promise to travel the world, living out of a suitcase, and win titles, he said.
"There's a couple of handfuls of riders with more [potential] than the others but I don't know if they have the drive to travel the world and win. A lot think they do but they haven't".
Meanwhile, the 125cc class was won by series leader Cody Cooper (New Plymouth) while Rueben Vermeer (Masterton) won the MNZ Cup Overs and Greg Cameron (Cambridge) took out the MNZ Cup Under series.
Katherine Prumm (Bombay) completed a cleansweep yesterday to head Mary Perkins (Tauranga) in the women's Championship event.
