Yamaha Riders Divided Over Tyres

Reports say that Yamaha has confirmed that its two main riders in the 2008 MotoGP competition will be racing on different brands of rubber. Valentino Rossi, five-time world champion, is set to switch to Bridgestone tyres from his current Michelin. However, the recently-signed Jorge Lorenzo, who has won the 250cc World Championship twice, will race on Michelins. To avoid any potential problems and to ensure total confidentiality, the two riders will have separate pits, managers and technicians.
