The flamboyant German went 1-1 on the fuel-injected and capable RM-Z250 and won a new legion of fans thanks to his duelling action with Musquin and mastery of the many jumps and leaps on the hard-pack and rough red dirt. 21,500 spectators revelled in the contest as the two protagonists pulled away from the pack in both races and soaked up the spotlight. Roczen was able to elude the Frenchman in the latter stages of the first 35 minute and 2-lap dash under hot sunshine and crossed the line over 20 seconds in front. The second moto decided the overall ranking and for two-thirds of the distance Roczen had to keep pace with Musquin. Finally he drew into a position to be able to attack and again there was no effective response from the number '1'.

Roczen was delighted with his second overall win of 2010 and his ninth podium from the 13 rounds of 15 held so far. It also meant that the 16 year old prolonged the course of the title dispute for another meeting as Musquin holds a gap of 72 with just 100 left to win.

Arnaud Tonus will also remember Brazil as the country where the Swiss raced to his best result yet in the MX2 class and in Teka Suzuki Europe colours. A strong third position in the first moto put the teenager on course for a possible first trophy but a harder second race on a rougher track saw Tonus come home with sixth and signify fourth overall. He is eighth in the MX2 standings, just one point behind Shaun Simpson and trails Jeremy Van Horebeek in sixth by nine points.

Rockstar Teka Suzuki World MX1 was minutes away from their third victory of the season at Campo Grande for the Grand Prix of Brazil and the 13th round of 15 in the FIM MX1 World Championship:

Some 21,500 spectators saw Clement Desalle take third position in a hot and difficult first moto and then suffer a technical problem while leading the second race that denied the Belgian team the top step of the podium. Steve Ramon rode through the pain barrier of a stretched right groin muscle to bravely capture fourth overall on the RM-Z450WS.

The dark red dirt of the new GP course created dust-clouds that plumed across the site on Saturday and formed difficult riding conditions for the riders in the qualification heat in which Desalle took third place and Ramon seventh as both Belgians exercised caution. The track itself involved many jumps and the watering required in containing the loose top soil meant that some sections were soft and rutted while others were hard.

Desalle slipped off twice in the first moto on Sunday but was quick enough to finish third by the flag. He was superior to the rest of the pack in the second outing but an electrical problem halted his progress and meant that rival Tony Cairoli was able to clinch the MX1 title. The 21 year old classified ninth. Ramon almost crashed in morning warm-up but in saving the motorcycle, over-extended his right leg and was forced to grit his teeth through two long 35 minute and 2 lap races to finish seventh and fourth.

With the World Championship tussle now over, Desalle has to concentrate on securing the runner-up slot in the 2010 competition. He heads David Philippaerts by 30 points and 100 remain on the table with two rounds remaining. Ramon is fifth and 12 points away from Max Nagl.

Rockstar Teka Suzuki World MX1 will return to Europe on Monday. Desalle will have a free weekend before the final two appointments of the FIM Motocross World Championship at Lierop in Holland and then Fermo in Italy occurring back-to-back. Ramon, meanwhile, will hope to attempt the penultimate meeting in the Belgian Championship at Orp-le-Grand.

Clement Desalle:

"I was leading the GP until we had the mechanical problem. I thought I was running out of fuel the lap before but then it stopped. We will have to see what happened. I made a few mistakes in the first moto but the speed was good. I was disappointed with the last lap because I had to change my line because of the backmarker and slipped away. I'm not injured, despite the mistakes, so that is a positive. Tony is World Champion now and we will try to step up another level and work towards the win next season."

Steve Ramon:

"This morning in the muddy conditions I made a little mistake. The bike slipped out of the rut. I wasn't crashing but I tried to save it and put my foot on the ground. I stretched my right leg and immediately pulled out of the session because I had so much pain in my groin. It was a tough day after that! It was difficult to ride. Somebody crashed in front of me at the start of the first moto but to be honest I could not ride flat-out all day because I had to be careful in the right corners with my leg. There were many ruts. I had to fight the pain for a long time. Hopefully the muscle is not too bad."

Ken Roczen:

"This was an amazing day for me. I have really improved my starts and that is something I really needed at this track. We had two hard fights with Marvin and I am so happy to take two wins. After the first moto I thought the second one would be really difficult but my condition was good and I could push right to the end; it was enough. It was a perfect race for the fans and they had an entertaining show! We have two more GPs now and I want another win before the end of the season."

Arnaud Tonus:

"The first moto was really good. I started around fifth and made it up to the podium place which was awesome. I just rode my own race and felt fast. I had a lot of fun and that paid off. I am a bit disappointed with the second moto because I lost any chance of the overall podium but for sure I am pleased with the result. I loved the track and the conditions. It was a bit muddy in the first moto but that was better than the dust of yesterday."
