The world champion finally heads out for a look at the conditions. I can't imagine his title rivals will be too far behind now.
Track is definitely getting busier now as conditions improve. Maverick Vinales and Fabio Quartararo have joined the action.
Binder dips into the 1m33s for the first time this morning with a 1m33.843s.
Binder keeps upping his pace at the top of the timesheets as he's now posted a 1m34.212s, while a couple more riders have taken to the circuit.
Francesco Bagnaia, among others, is carrying a lovely tribute to the late Luca Salvadori on his bike this weekend.
Another gain for Binder on his seventh flying lap of the session with a 1m34.349s.
Conditions clearly can't be too bad as Binder slides the KTM into Turn 8!
Binder continues his run at the top of the order with a 1m34.673s.
Binder improves to a 1m35.411s.
Still only three lap times on the board so far. Given we've already had a race weekend at Misano and a test in the last two weeks, the riders won't be missing out on too much right now.
Binder continues to improve his lap time. He's now put in a 1m37.287s with just over 10 minutes of the session gone.
The earlier rain appears to have left quite a lot of dirt off the racing line, which the riders will have to be careful of.
