From a press release issued by Marlboro Yamaha:

VICTORIOUS MARLBORO YAMAHA TEAM CONTINUES HARD WORK AT BRNO

Italian Max Biaggi did not have long to celebrate his first win aboard the Yamaha YZR-M1 before he was back in action for half a day’s testing at the Brno track. The Marlboro Yamaha Team man capped pole position on Saturday with a win in yesterday’s Czech Republic Grand Prix at Brno. He and Spanish teammate Carlos Checa carried out further tests on the latest development of M1 chassis today plus some tyre tests.

Biaggi had opted to race the existing version of M1 chassis having tested the new development during practice for the race. It proved to be a good decision as he emerged victorious, but he was still keen to carry out further set-up experiments with both versions today. In sweltering conditions he completed a total of 39 laps with a best time of 2:00.8, a second shy of the best-ever lap of the circuit that gave him pole on Saturday. Satisfied with the work he had done, Biaggi left the track just after lunch.

Carlos Checa, who took fifth place yesterday riding with the new chassis, rode a total of 63 laps today and finished with a best time of 2:00.7. Checa was also working on fine-tuning suspension set-up as well as testing new Michelin front tyres. He will return to the track tomorrow for further tyre tests.

Testing alongside the Marlboro Yamaha men were the Gauloises Tech 3 Yamaha, Red Bull WCM Yamaha and Telefonica Movistar Suzuki teams.
