Maverick Vinales finished on top of the timesheets during both days of his Yamaha debut during official testing at Valencia.
Reigning champion Marc Marquez made a fast start to Wednesday morning, beating the Tuesday best of Vinales. Marquez appeared to be using the new 'big-bang' style Honda engine in this year's RC213V, as well as having a standard 2016 bike plus a full 2017 (black) machine available.
Andrea Dovizioso later took over at the top, riding the new Ducati, before Vinales became the only rider to break the 1m 30s barrier.
This week's two-day outing marked the first appearance for triple MotoGP champion Jorge Lorenzo at Ducati, Vinales at Yamaha, Andrea Iannone at Suzuki, Bradley Smith and Pol Espargaro at KTM, Aleix Espargaro at Aprilia, plus Alvaro Bautista and Karel Abraham at Aspar.
The four rookies were also on track: Johann Zarco and Jonas Folger at Tech 3 Yamaha, Alex Rins at Suzuki and Sam Lowes at Aprilia. Lowes did not ride today following his Wednesday fall, while Danilo Petrucci returned to Italy for family reasons and was replaced by Michele Pirro.
The Wednesday session was red-flagged from 11am to 12pm due to heavy accidents for new Suzuki riders Alex Rins and Andrea Iannone at Turn 12. Rookie Rins was conscious but taken to the medical centre, then hospital, for precautionary checks which revealed damage to two vertebrae.
Track action, which began at 10am, was extended by half-an-hour until 5:30pm as a result of the earlier delay.
Private tests will be held at Sepang (Yamaha) and Jerez (rest of the manufacturers) next week, before the winter testing ban begins on December 1.
