With two WorldSBK tests under our belts, we are now just days away from the 2019 MotoGP preseason starting. The entire MotoGP field, minus the injured Jorge Lorenzo, will take to the Sepang circuit on 6th February for three days of testing.
But before that, from 1st to 3rd of February – that's Friday through Sunday – the MotoGP factories will be present at Sepang for the first shakedown test of the year. Test riders from all six factories will take to the track, and will be joined by the riders for the factories with concessions, who are allowed unlimited testing.
The original point of the shakedown test was to allow factories to ensure that all of the parts they have brought for their contracted riders (e.g. full-time entries in MotoGP) to test are actually working, and do some preliminary preparation ahead of the official test. After all, the full-time riders cannot afford to waste a day while engineers and mechanics try to figure out why something which worked at the factory has ceased to work at the race track, for example.
