Stoner moved 10 points clear in the championship as previous leader Valentino

Rossi could only finish 10th in Turkey on the Fiat Yamaha, three places behind

reigning champion Nicky Hayden on the Repsol Honda.

British teenager Bradley Smith had the best ride of his career before

eventually having to settle for eighth place in the 125cc class.

Smith was lying eighth in the closing stages when he reduced the gap on the

seven-rider leading group and was in contention for fifth at one point.

But a clash with another rider on the final lap as Smith tried to take fifth

on the Repsol Honda meant he had to drop to eighth, equalling his best race

finish.

After a poor qualifying session which had seen him line up outside the top 10

on the grid it was a good response from Smith.

He said: "I don't know what went wrong yesterday. I came out this morning and

felt really positive.

"I had a few moments catching the group in front.

"I was a little bit gutted. It was so close to being an awesome race but it

was still great. I could smell it, it was so close.

"The team worked on the engine, the gearbox and me last night and it

certainly paid off. For next time (in the same situation) I have learnt a little

more what to do in that situation."

The 125 cc race was won by Simone Corsi (Aprilia) as Scottish teenager Kev

Coughlan was an impressive 21st on only his second GP appearance and Danny Webb

was 23rd.

The 250cc race was a three-way battle in the closing stages before Andrea

Dovizioso snatched the win on the last lap on the Humangest Honda after getting

the better of championship leader Jorge Lorenzo (Fortuna Aprilia) and Alvaro

Bautista (Aspar Aprilia).
