Madrid, Aug 18 (IANS): Reigning MotoGP World Champion Marc Marquez said on Tuesday that he would not give up trying to catch compatriot Jorge Lorenzo and Italian Valentino Rossi despite losing ground to the former at Czech Grand Prix at Brno.

Lorenzo was dominant enough to win on Sunday as Marquez was denied a victory. The Honda rider, however, finished second ahead of third placed Rossi. Marquez now has to make up 52 points on the Yamaha duo with seven races to go but he insists he will push really hard for the championship with Honda-friendly tracks coming up.

"It's difficult to catch up 52 points to one rider and it's even more difficult to catch 52 points to two riders. Both of them have good pace; they are (both) on the podium again like at Indianapolis," Marquez was quoted as saying by motorsport.com.

"But we will try to do our best; understand during the weekend how the bike is, where the weak points are for next year. We will take risks and we will see the limit. Brno was one of the most difficult for Honda and our problems and our riding style; now we come to circuits that should be better."

In the last two races, the 22-year-old Spaniard has been beaten to the first corner and Marquez admits that the launch off the grid has become a major weakness for Honda.

"We are losing (ground) under acceleration and at the start. In first gear we start well, but then we go through the gears and we have a lot of wheelie, and this is one of the biggest problems," he explained.

"With this wheelie the bike is really physical, for the hands and everything. We are trying to work on it for next season; it will be like this for this season."
