The balance of power on the MotoGP grid already seems to have shifted, for all sorts of reasons. The construction used on the 2020 rear Michelin tire is having a major impact on the performance of the bikes, with more grip available in all conditions, and more durability. But because the tire has changed, it will take at least the first part of the season for the factories and riders to figure out how to get the most out of the tire. That means we are likely in for a fair few surprises throughout the year. This could be like 2016 again, some inside Michelin believe. That doesn't mean that we can share the championship spoils out among the bikes which are ahead at the Sepang test already. The test raised more questions than it answered. It's not so much that factories and riders were sandbagging, more that so much is new this year that most factories are closer to the beginning of their development project than the end. Add in the complication of Marc Márquez coming off his second shoulder surgery in two seasons – and Miguel Oliveira and Taka Nakagami in the same boat – and there are more unknowns than knowns. The balance is likely to shift several times though the 2020 season. Which is good for fans, though it tends to annoy the manufacturers.
