One of the big talking points from last week's Sepang MotoGP test was the performance of the new Michelin rear tire. The new construction tire, first tested at the Barcelona test in June 2019, met with widespread praise. The new rear had more grip, both on the edge of the tire, and in the traction area, the slightly fatter part of the tire which riders use just as they pick up the bike on exit.
The new tire was popular with everyone, although some riders believed it benefited the bikes which use a lot of corner speed, like Yamaha and Suzuki, more than the point-and-squirt bikes like the Honda and Ducati. Riders who carried a lot of corner speed could immediately use the additional edge grip. Riders who needed to pick up the bike and drive out of corners felt they needed more time to understand how to get the most out of the tire.
The Yamaha riders were overwhelmingly positive about the new rear Michelin. "Since the first lap I did on those tires in Montmelo last year, I felt really good," Maverick Viñales said. "Also for the way I pick up the bike, it's quite good."
Monster Energy Yamaha teammate Valentino Rossi agreed, but pointed out that the new Michelins benefited everybody. "The tires from Michelin are better," the Italian said. "This is good but unfortunately the tire from Michelin are for everybody. So we make the step but also the other guys."
Franco Morbidelli described the tire as filling in the holes where the Yamaha lacked drive and grip in 2019. "The new tire gives more grip and it fills our emptiness with grip that we had last year, so that's positive for us. This tire performs better so edge grip and drive grip."
