A few thoughts on things I saw walking up and down pit lane.
First, it is clear that teams are worried about tire temperature. The factory Ducatis, the factory Yamahas, and even Andrea Dovizioso were using the silver wheels, using special paint to dissipate heat more effectively.
Aprilia appear to have the most sorted motorcycle, judging by the parts and tools in the garage. Where other teams and factories have shocks, fork springs, and even swingarm linkages (Suzuki) lying in the garage, Aprilia are just changing tires. That is ominous for the rest of the grid.
As one of the factory KTM riders left pit lane, a caught a glimpse behind the bottom of the fairing. It looked like they have a lot of hydraulics there, which are most likely used to control the ride-height device. Locating it under the bike is ideal in terms of weight distribution.
