The inaugural MotoGP test at Indonesia's new Mandalika circuit began in wet (and dirty) conditions on Friday morning.

Johann Zarco was fastest by the end of the opening hour, when the rain had stopped, with the session then red-flagged to try and clean the dirty surface.

After a lengthly clean-up, the track re-opened for testing shortly before midday, with Francesco Bagnaia (on slick tyres) leading an all-Ducati top three by 1pm.

Improving conditions mean lap times have tumbled ever since: Marc Marquez leading a Honda one-two as of 2pm, but dropping to 19th by 3pm - such was the pace of improvements - when world champion Fabio Quartararo was fastest.

By 4pm, Quartararo's former team-mate Maverick Vinales - the final rider on track - had jumped to the top for Aprilia, with Brad Binder taking his KTM to the top just before 5pm.

Testing was due to finish at 5pm, but day one has been extended until 5:45pm due to the earlier clean-up.

The three-day outing, which follows hot on the heels of a two-day Sepang test, marks the final chance for official MotoGP track time before next month's Qatar season-opener.

Gresini Ducati's Enea Bastianini was a surprise fastest from the Aprilia of Aleix Espargaro in the rain-interrupted final day at Sepang, which saw the fastest ever two-wheel laps of the Malaysian track and the top ten riders (from five manufacturers) covered by 0.299s

As well as the ever present threat of more rain, MotoGP teams and riders have the added challenge of learning a new circuit and working through an expanded range of Michelin tyres in preparation for the March 18-20 race weekend, the first Indonesian motorcycle grand prix since 1997...
