Having won an amazing 50 races during just five and a half years in the premier 500cc/MotoGP class – including eight wins from the first ten rounds of this season – what keeps six-times world champion Valentino Rossi motivated?

"Sometimes (motivation) is difficult, but to ride the bike at the limit is my first passion," he explained. "When I win for sure the taste is different to when I finish second, so this is the biggest motivation. But when my taste to ride the bike at the limit is different then maybe I will decide to finish."

Rossi will aim to move a step nearer to winning his fifth consecutive premier-class crown, which would match the world title achievements of Mick Doohan, at the Czech Republic Grand Prix on August 28.
