MotoGP rider comments about the racetrack that will host the Thailand Grand Prix in early October generally weren't very positive prior to traveling to the Buriram province earlier this month for the second of three preseason tests scheduled before the opening round of the series in Qatar on March 18. Following three days of lapping the 12-turn, 2.83-mile circuit, however, some of the riders had a change of heart. Here are a few of their comments after experiencing the Chang International Circuit for the first time.

Marc Márquez, Repsol Honda: Regarding the track layout, it seemed quite fast to me when I lapped it on a scooter, but on my bike I realized it was slower than I was expecting with many second- and third-gear corners. Still there are some hard acceleration and braking points, and it will probably be challenging to manage tire life.

Andrea Dovizioso, Ducati Team: It's an unusual track, and it's not so easy to ride in this track. It looks easy, but it's strange. Some braking points are quite hard at the beginning, but in the last part of it we are not able to keep a lot of pressure on the front brake. You have to be very precise in the last part of the track because you have to make the line with the throttle and with the slide. And it's not so easy; sometimes you are able to make a good line, but most of the time, not... I think there are three or four corners where it is quite easy to overtake.

Dani Pedrosa, Repsol Honda: The circuit is quite narrow, so it's important to use the right lines and carry speed.

Danilo Petrucci, Alma Pramac Ducati: The track has good grip. The setup we imagined to go in one way, but there are more flowing and fast corners [than we thought] where you need a lot of load on the front.

Jack Miller, Alma Pramac Ducati: The track is so short! It's relatively simply. The runoff areas are okay, and there are a couple of bumpy corners but nothing too dramatic. The only thing is that last corner: If someone gets a little bit overambitious it could end up pretty hairy. The rest of the track is pretty safe. The first sector suits the Ducatis, but you've just can't get too ambitious into turn 1 because you need to prepare that exit so well for the long straight. That's definitely one of the key points. Slipstream is also something that could help here.

Valentino Rossi, Movistar Yamaha: The feeling with the track is not too bad, I expected it to be worse. First of all, the track is in good condition. It's clean and the asphalt has good grip; this is very important. About the layout, I expected it to be similar to Austria, so I was very worried, but when you ride maybe it is more similar to Argentina. It's good to ride, you have a good feeling, you enjoy. The track is not very difficult; technically it's quite easy, but anyway it's fun.

Maverick Viñales, Movistar Yamaha: I like the track a lot. It fits my riding style quite well with these flowing corners.

Johann Zarco, Monster Yamaha Tech 3: I'm really happy about the new track. The layout is nice and better than I expected.

Aleix Espargaró, Aprilia Racing Team Gresini: To be honest, the track surprised me. I had more fun than I thought I would. The first part is not particularly interesting with all the straights connected by braking sections, but overall it is a nice track. It is precisely in the first part where we need to work because we are losing a few tenths in acceleration from low speed. On the flowing parts, on the other hand, we are very competitive.
