Andrea Iannone led a Ducati one-two on the first day of the final 2015 pre-season MotoGP test in Qatar.
On a very encouraging day for Ducati at Losail, Andrea Dovizioso and Iannone established themselves up front early on as most waited until night fell to undertake concerted running.
World champion Marc Marquez put his Honda ahead for a spell, but then a 1m55.265s from Iannone on the new GP15 re-established Ducati's advantage.
Dovizioso moved up to second shortly afterwards, 0.098 seconds off his team-mate and 0.191s ahead of Marquez's Honda.
Suzuki also showed excellent form, as Aleix Espargaro went fourth fastest for the returning team.
His team-mate Maverick Vinales crashed both his main and spare bikes during the day. He was unhurt and ended up 11th.
With Dani Pedrosa moving the second Honda up to fifth with a late run, Yamaha's top runner was Jorge Lorenzo in sixth. The Spaniard felt Yamaha was struggling particularly for grip on the still-dirty track surface.
He was two places ahead of Valentino Rossi, who crashed at Turn 8 early in the session and did not go for qualifying-style run later on as he had lost a set of tyres in the accident.
Cal Crutchlow continued his progress from the second Sepang test to put his LCR Honda between the Yamahas in seventh.
Two further British riders completed the top 10, with Bradley Smith ninth and Scott Redding and Marc VDS having their best winter result yet in 10th.
While Suzuki had another good day, the going got tougher still for fellow factory returnee Aprilia.
Alvaro Bautista and an unwell Marco Melandri brought up the rear, behind Ioda's ART version of the same bike in Alex de Angelis's hands.
