Factory Yamaha's Ben Spies is still suffering from the arm numbness that caused 'the hardest race' of his career last time out at the Brno MotoGP round but he says it is a lot better than two weeks' ago.

The former World Superbike Champion pinched a nerve in his neck which is causing the numbness in his left arm and he compensated so much in the Czech Republic, he hurt his right arm during the race, saying he never wanted to quit as much as that day.

“I’m really hoping to be completely fit for this weekend. I’ve still got some numbness in the arm but it is better than it was at Brno. We’ve been working hard to get it right and we will of course give it 100% as always. I’ve been looking forward to this race all year; it was pretty crazy last year as a rookie to take pole and a second in the race. We’re going to put on a good show for all the home fans and see what we can do," said Spies.
