Alvaro Bautista made a 'big mistake' heading into turn one of Saturday's Dutch MotoGP at Assen, but the Spaniard is not a dangerous rider.

That's the view of Andrea Dovizioso, one of the riders out-braked by Bautista just before he lost the front of his Honda and wiped-out world championship leader Jorge Lorenzo.

"It was really close to me so I saw how late he braked. He made a big mistake," said Dovizioso.

"This can happen because you don't have your [normal brake marker] to understand where to brake at the start. But you still don't have to make a mistake and how big a mistake he made was too much I think.

"Alvaro is not a dangerous rider, so maybe a penalty is too much, but for sure a big warning. He didn't want to do it, but every rider in MotoGP, Moto2 takes a lot of risk and if you have some warning the next time you are thinking about that."

Bautista was indeed penalised by Race Direction and will start from the back of the grid at next Sunday's German Grand Prix.
