A number of the MotoGP teams have had a busy test at the Aragon circuit over the past two days. This is the test which played a role in not being able to move the Silverstone race to the Monday, a public holiday in the UK, as the trucks needed to travel the 2000km from Towcester to Alcañiz and set up ready for testing.

On Wednesday, Suzuki, Yamaha, and KTM were the factories taking to the track, with the Pramac Ducati squad also present. Thursday saw Yamaha and Pramac depart to make way for the factory Ducati squad. The teams were met with much better weather than at Silverstone, allowing two full days of testing, with the track improving as it got cleaned up with bikes circulating.
