Sunday marks the start of official 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 bikes #T2 and #T3.

Morning rain meant it was a wet start to testing, but the track was dry enough for slicks shortly after 1pm.

Testing began at 10am and concludes at 6pm.
