REIGNING MOTOGP World Champion Valentino Rossi has been out on four wheels again - this time joining his motorcycle racing buddies at Jeepers Kart track, Cattolica.
The nine-time world champ, who recently announced he is to race for Ducati from 2011, was joined by Marco Simoncelli, Andrea Iannone and Mattia Pasini at the karting venue.
Rossi, an accomplished racing driver, turned down an offer to move to Ferrari F1 in 2011, after impressing team bosses when he drove the squad's 2009 car in Spain.
