Spies (swing arm failure??) should leave Yamaha before something really bad happens.
After today Rossi has to consider Ducati a waste of time.
Honda and Yamaha have a tech edge that will be hard to overcome.
If either or both build production race bikes, CRTs are gone.
If the CRTs had a displacement advantage, would they do better ???
How about
Moto3, 300cc twins.
Moto2, 600cc stays the same.
Moto GP 900cc.
300,600,900 , a nice progression.
Remember when, with 800cc, the tires would be working well at the end of the race.
As soon as they went to 1000cc the tires would no longer last.
World superbike has the same problem, Corser would get the hole shot and by lap 6 his tires were shaged.
Too much HP.
Years ago Ten Kate learned to adjust HP to match tire durability.
Rae often runs a ways back from the front, then moves up as other rides lose their tires.
Finally, this year, all the others have finally caught on.
