What did we learn from the first day of testing at Sepang? Exactly what we expected to learn. Some riders have adapted quickly, others less quickly. The Michelins have made a big step forward, and the teams have started to understand the Michelin tires better.
The spec-electronics still need plenty of work, but are pretty usable in their current form (and well liked by the riders). Yamaha and Ducati have adapted well, Honda not very well at all, with the possible exception of Dani Pedrosa.
Above all, we learned that it is too early to be making any judgment calls, and that everyone still has a lot of work to do, and a lot of room for improvement. Today’s outcome is interesting, but not definitive.
In other words, if your favorite rider is near the top of the timesheets, you can feel optimistic that they will do well in 2016. If your favorite rider is nearer the bottom, you can console yourself with the fact that there is hope, and that testing will solve the worst of the issues.
