The sun finally shining down on Motorland Aragon must have looked inviting for the premier class gang, with some race trimmings to be found. The first few minutes saw Valentino Rossi leading briefly, Alvaro Bautista sliding out after getting too comfortable with Dani Pedrosa’s rear tyre and Marc Marquez joining Cal Crutchlow in various gravel traps around the track.
Their Honda colleague was more well-behaved and Pedrosa sat at the top of the timesheets for most of the session. The Spaniard continued to improve throughout FP4, his time only bettered by a final lap on soft tyres from Maverick Viñales. The Yamaha rider looked in pretty bad nick at the start of the session but once he ditched his old used medium tyres he was right back at the top.
