Marc Marquez declares MotoGP title bid over after British GP crash

The Honda rider had edged back into contention with back-to-back wins at the Sachsenring and Indianapolis, raising hopes of a three-way title fight with Yamaha duo Valentino Rossi and Jorge Lorenzo.

But a crash when running a close second behind Rossi at a wet Silverstone on Sunday has left him 77 points off the lead with only six races remaining.

"We've lost our hope of the championship, but we will try to win many, many races - as many as possible from now to the end of the season," said Marquez.

Asked if that meant he would take a win-or-nothing approach to the rest of 2015, Marquez joked: "Not win or zero, though that's more or less my style..."

But he added that he had been riding at the absolute limit in recent races anyway to try to regain ground on the Yamahas following a messy start to the season in which he had appeared on the podium just twice in the opening seven rounds.

"I will try to win but when it's not possible I will try to finish second or third," he said.

"It won't change my level a lot because I was already taking a lot of risks in these last races."

Rossi and Lorenzo had previously been unwilling to discount Marquez as a title threat even when he was falling behind in the early part of the season.

But following the British GP both admit the title race has become a two-way fight.

"He's almost out of the championship, definitely," said Lorenzo of Marquez.

Rossi, who leads the standings by 12 points after Lorenzo struggled for comfort in the wet and finished only fourth, said gaining a much bigger cushion over Marquez was the biggest success of his day.

"I don't want to say it's closed [for Marquez], but now he's very far behind," Rossi said.

"It's very important to have a big advantage on Marquez."
