Álex Márquez could not capitalise on his qualifying pace and settled in eighth position but his attempt to move forward was compromised by rear grip issues.
The 20-year-old Spaniard crashed just after overtaking Marcel Schrötter for seventh place with 16 of 23 laps remaining.
Álex Márquez: “I am very angry with myself because I didn’t feel very good in the race and I don’t know why. I struggled a lot with rear grip and could not overtake the riders ahead of me and then when I did pass Schrotter I tried to push too much and crashed. I am sorry for the team and I need to concentrate on getting better results. Now I look forward to Phillip Island, a track which I enjoy very much”.
