FP1 got underway in the dry, but just five minutes into the session the rain arrived, and Gerloff elected to remain in the garage. As the FIM Superbike World Championship riders initially went out on slick tyres, the best times were set after only a few laps, with Nozane going 12th fastest.
In the second free practice, wet conditions welcomed the riders once again. Gerloff showed great pace early on before falling at Turn 12, but the GYTR GRT Yamaha WorldSBK Team did a great job to repair the bike and get the American back out on track in the final minutes.
On the other side of the box, Japanese rider Nozane enjoyed a strong afternoon and found a good rhythm to end the session in eighth.
The two GYTR GRT Yamaha WorldSBK Team riders will be back tomorrow, firstly with FP3 at 09:00 local time (CEST), followed by the Tissot Superpole at 11:10 and Race 1 at 14:00.
