The testing at Sepang involves all the factories in the paddock including Yamaha, Honda, Ducati, Aprilia and Suzuki.
Colin Edwards and Katsuyuki Nakasuga test for Yamaha, Hiroshi Aoyama for Honda, Randy de Puniet for Suzuki, Michele Pirro for Ducati, and Michael Laverty for Aprilia.
Stepping up in wheel size to 17 inches, the test riders will not only be working on the evaluation of the tyres, but also on the characteristics of the bike with the new wheels.
Piero Taramasso, Manager of Michelin 2Wheel Motorsport Activities, commented: "When we do a test like today we bring seven different fronts and four of five different rears. So we use the test riders to do a pre-screen, and then when we select the best one, we use that with the official riders.”
"If we respect the plan, we think that by mid-season around July, we will fix the front casing and rear casing, and we’ll know about all the compounds we need to cover all the race tracks."
