Even Yamaha is not in the top ten. Indeed this is just the initial test, there are still some tests and of course the race series. Of course this result makes the yamaha supporters worried. Top speed problems should start to be developed by Yamaha, they should immediately overtake the top speed of other motorcycles. Otherwise the title will probably be difficult they can get.
This year Yamaha is a manufacturer with the status of defending champion because last season Yamaha was the world champion in MotoGP.
But considering that other manufacturers have started to develop in two steps, then Yamaha should also develop for one step even though it will not be enough to compete but can be very qualified for their initial capital.
Even I was surprised because Marquez had already tested and he became the fastest rider. Aprlia, Ducati has a power similar to Honda. They'll probably be the candidates for next season's championship. But I don't know, it's possible that top speed is not the main factor but I think it's support that.
Top speed is indeed not the main factor that must be considered because considering the 2020 season where the Suzuki manufacturer managed to become the MotoGP world champion by only relying on good handling and motorcycle balance, while the top speed was not so fast.
