The second and final day of the opening 2021 Qatar MotoGP test is underway at Losail.

Aleix Espargaro and Aprilia were the surprise leaders on day one, but can they hold their advantage?

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.

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, followed by ten minutes reserved for practice starts.
