Marvin Musquin could wrap up the MX2 world championship this weekend for his second straight title.

With just three grand prix’s to go before the end of the FIM Motocross World Championship, this weekend’s Grand Prix of Brazil in Campo Grande will present championship leaders Tony Cairoli (MX1) and Marvin Musquin (MX2) the first chance to grab the 2010 titles.

Red Bull KTM Factory Racing MX1’s Cairoli is on a mission to hand KTM their first MX1 title since Heinz Kinigadner took the title in the 250cc class in 1985.

The Italian, who is onboard the revolutionary KTM 350 SX-F, has won the latest three grand prix to increase his advantage over runner up Clement Desalle.

The two are now separated by 84 points with a total of 150 points up for grabs and Cairoli sees his first chance to wrap up his fourth world title already this weekend. Last year at Canelinha a knee problem hampered Cairoli’s performance.

Being currently in second place, Rockstar Teka Suzuki World MX1’s Desalle knows he will have to give his best if he wants to cut the gap from Cairoli.

Desalle came out victorious of last year’s Brazilian Grand Prix and is hungry to add more wins to his current record of two, the Belgian having finished on the podium other eight times for a total of ten podium appearances – as many as Cairoli.

More than 50 points away from Desalle is third placed David Philippaerts of Yamaha Monster Energy Motocross. The hard charging Italian will head to Brazil to make up for a bitter Czech Grand Prix and defend his position in the championship, which riders such as Max Nagl and Steve Ramon are looking at since their top five finishes in Loket.

Red Bull KTM Factory Racing MX1’s Nagl wishes to make the most of a difficult season –he was second in the championship until he broke his collarbone in France- by taking an eventual third place.

Nagl is now 12 points behind Philippaerts and has positive memories of last year’s trip to Brazil, when he took third on Canelinha’s podium.

Rockstar Teka Suzuki World MX1’s Ramon is also close to the top three, the Belgian currently holding fifth place in the championship. The two-time world champion is only six points behind Nagl and was second in Canelinha last year.

Ken De Dycker follows Ramon in sixth while Tanel Leok is making up ground courtesy of his latest podium and heat win at Loket.

The Estonian is followed by Xavier Boog, making his return to racing after Lommel’s knee injury, while fellow Honda riders Eugene Bobryshev and Guarneri complete the top ten.

Marking his comeback to victory in Czech Republic, Red Bull KTM Factory Racing MX2’s Musquin leads the MX2 World Championship since Portugal and with a current advantage of 78 points from runner up Roczen he holds a chance to collect his second title in Brazil – as he did in 2009 at Canelinha by winning the overall.

Teka Suzuki Europe World MX2’s Ken Roczen instead will try and get as many points as he can among the 150 the championship can still pay.

The 16-year-old German is 78 points behind the French leader Musquin and needs to do a good performance in Brazil if he wants to keep on fighting for the championship.

After obtaining his maiden GP victory in Sweden, third in the championship Kawasaki CLS’ Frossard has not been able to be back on the podium even being the poleman in the Bonver GP of Czech Republic.

Last year the French was third in Brazil, so Campo Grande might bring him back to the top three and cut the 45 points difference from runner up Roczen.

Red Bull KTM Factory Racing MX2’s Jeffrey Herlings is fourth in the championship but the crash in the second moto during the Bonver GP of Czech Republic put an end to his 2010 season.

The 15-year-old Dutch rookie will need surgery on his right shoulder, but will have enough time to recover and be back in the following season and proof that his two GP victories were not eventual ones.

His teammate Red Bull KTM Factory Racing MX2’s Simpson completes the top five and this weekend’s GP gives him the opportunity to climb up one position in the championship standings and be closer to the top three leading riders.

The Brit has shown that he has good starts as well as good speed, but he is still working on his rhythm to be able to start and finish among the top five riders.

American Zach Osborne will debut in the Brazilian soil in the FIM Motocross World Championship and will try to make his come back to the podium and enter the top five in the standings of the series.

Seventh in the championship is Jeremy Van Horebeek, eighth is his compatriot Roelants and ninth is Swiss Arnuad Tonus, but among them there are only nine points difference. Completing the top 10 is the Finish Kullas.
