Viñales, Zarco, Marquez top on Day 1

It was a slow start to action at Valencia as sunny skies hid cool air temperatures, but the engines soon fired up to full speed once the first forays had been made. By the end of the first day, Maverick Viñales (Movistar Yamaha MotoGP) was top, taking over in P1 late in the day and ending the day two tenths clear of Johann Zarco (Monster Yamaha Tech 3). Movistar Yamaha had four combinations of chassis and engine to test, with Zarco, meanwhile, setting his fastest lap on the 2017 M1. The big visual headline from the early part of the day saw Viñales head out first sporting a new aerofairing on his M1, and it wasn’t long before teammate Valentino Rossi did the same. Viñales put in 80 laps, Zarco 53 and Rossi 63, as the ‘Doctor’ took fourth on the timesheets to slot in just behind reigning World Champion Marc Marquez (Repsol Honda Team).
