Suzi Perry introduces live coverage of the San Marino Grand Prix. Although the Misano circuit is Valentino Rossi's home track, the Italian has had mixed fortunes since MotoGP returned there two years ago. In 2007 his engine failed, but last year he won, equalling Giacomo Agostini's premier class record of 68 wins. Casey Stoner will be absent from Misano this year as he battles illness, but James Toseland will be looking to maintain his recent form. Commentary by Charlie Cox and Steve Parrish
