Monday marks the second day of 2018 MotoGP testing at Sepang in Malaysia.

All 23 confirmed race riders are present, plus some test riders, while Yonny Hernandez has been called-up by Tech 3 as they continue the search to replace Jonas Folger.

Rookie Thomas Luthi is making his Marc VDS Honda debut after missing the end of the 2017 season due to injuries at October's Malaysian Moto2 race weekend.

Kohta Nozane and Katsuyuki Nakasuga are the Yamaha Test Riders listed as present, but appear to be alternating between three different bikes.

Testing began at 10am, but a damp track kept all riders in the pits until 11am. The action concludes at 6pm.
