It's been a difficult test at Valencia. The weather simply hasn't played ball. Tuesday started wet, took a few hours to dry out, then rain started falling around 3pm, meaning the riders effectively had around two and a half usable hours on track. Rain on Tuesday evening meant the track was wet on Wednesday morning, and in the chill of a November morning, it took a couple of hours before the track dried out enough for the riders to hit the track.
At least it stayed dry and sunny throughout the day, and the last couple of hours saw the best conditions of the test, times dropping until falling temperatures put paid to any thought of improvement. The teams may have lost time, but at least they had a solid four and a half hours of track time to work.
For half the factories, what they were focusing on was engines. Yamaha, Honda, and Suzuki all brought new engines to test, and in the case of Yamaha and Honda, two different specs. Ducati was mainly working with a new chassis, aimed at making the bike turn better. Aprilia had a new engine and a new frame to try. And as usual, KTM had a mountain of parts and ideas to test.
