It was a stellar day for Gerloff, who was riding the wave of his very positive first race on a Yamaha M1 in the MotoGP round at Assen last weekend. The American used Free Practice 1 to introduce himself to the track and ended the session in fifth place with a 1'28.681. By the time the afternoon session came around, Gerloff was already well acquainted to the circuit, and the 25-year-old topped the timings thanks to a 1'27.524, which was good enough for 0.317s quicker than his nearest challenger.
Overall though, it was a bittersweet day for the GRT Yamaha team, with Kohta Nozane electing to withdraw from the weekend following a distal phalanx fracture on his middle finger (right hand) sustained at the Navarra test. The Japanese rider ran four laps in FP1, but was concerned about his and the other riders' safety due to the nature of his injury.
