Defending world champion Valentino Rossi won the opening MotoGP race after Casey Stoner crashed while in the lead, ending his undefeated streak from 2007. This was also the first race for the newly formed Moto2 class, which was introduced as a replacement for the 250cc two-stroke class. All bikes in this class were powered with 600cc four-stroke engines based on the Honda CBR600RR. This event was also known for Shoya Tomizawa's first and only Grand Prix win before he was killed in an accident at the 2010 San Marino motorcycle Grand Prix.
