Tony Cairoli won an action-packed second moto in Campo Grande, Brazil, to clinch the 2010 MX1 World Championship title on Sunday.
Riding KTM's revolutionary new 350 SX-F motocross, the Italian secured his fourth world title two GPs before the end of the season.
"I didn't expect to win here but its always nice to be world champion as soon as possible," Tony said. "I didn't take any risks and I was also a bit lucky that Desalle stopped, but that is racing.
"I am very happy with the new bike. I never had to stop because of any technical problem and that is really important if you want to be consistent.
"I love this bike and the whole team, they have helped me a lot." –Cairoli
Cairoli has won seven GPs and 13 of 26 individual motos this season, although his latest win was far from straightforward, with a crash in the second moto forcing the champion to stage a dramatic fight back to the front.
The Italian was chasing rival Clement Desalle when he crashed and found himself back in fourth place. Like all good champions, however, he drove on, hitting the gas to register the quickest times on the bumpy Brazilian track.
He had Desalle in his sights once more and on the very last lap the Belgian's bike failed, leaving Cairoli to charge through the checkered flag for the victory.
KTM teammate Max Nagl joined Tony on the podium in third place and Rui Goncalves finished in fifth overall, an excellent result for the rider who returned this season following serious shoulder surgery.
"It is always good to race in Brazil because it's like a second-home GP for me," said Goncalves. "I was sick during the week and had to go on antibiotics so I would be able to race. Today I fought hard to stay up front and I had two great races. This was my best GP so far. The speed is there and I can run with the best guys."
In the MX2 class, Ken Roczen topped the podium over Championship leader Marvin Musquin, the two battled it out for victory in each moto. Frenchman Musquin still holds a 72-point lead over his rival though, with just two GPs of the season to go.
Lierop, in Holland, hosts the penultimate stop during the first week of September before the curtain comes down in Fermo, Italy, a week later.
