2021 Qatar MotoGP Test, Losail - Live Sunday Updates

Aleix Espargaro and Aprilia were the surprise leaders on day one, but can they hold their advantage on the final day of the opening Qatar MotoGP Test.

With the Sepang test cancelled, Qatar is the first time most riders have been on a MotoGP bike since the chequered flag waved at Portimao last November.

Joan Mir and Suzuki are starting their title defence, while Pol Espargaro makes his debut at Repsol Honda and Danilo Petrucci at Tech3 KTM.

Other riders changing teams but not machines include Fabio Quartararo at Monster Yamaha, Valentino Rossi at Petronas Yamaha, Jack Miller and Francesco Bagnaia at Ducati Team, Johann Zarco at Pramac Ducati, Alex Marquez at LCR Honda and Miguel Oliveira at Red Bull KTM.

The MotoGP regulars are joined by Factory test riders, including Shakedown pace setter Stefan Bradl (Honda) - also substituting for the injured Marc Marquez - new Yamaha signing Cal Crutchlow, 31-time MotoGP race winner Dani Pedrosa (KTM) and former World Superbike champion Sylvain Guintoli (Suzuki).

Crutchlow will be sharing M1s with Yamaha's Japanese test riders Katsuyuki Nakasuga and Kohta Nozane. The three bikes, which appear to include both the 2019 (A-Spec) and 2020 (Factory-Spec) models, are labelled '#T1', '#T2' and '#T3'. Official timing only lists the bike, not the rider.

Testing takes place from 2pm to 9pm each day, followed by ten minutes reserved for practice starts.

The second and final pre-season test will then be held at the same circuit on March 10-12, venue for the season-opening race on March 28, then round two on April 4.
