Nicolas Terol reasserted his superiority over the rest of the 125cc field on Friday afternoon with a dominant performance in second practice.

The Spaniard saw his championship lead slashed by Johann Zarco at Brno and was forced to play second fiddle to the other Derbi of Efren Vazquez this morning, but the Bankia Aspar man was back to his brilliant best in FP2, clocking a 1:49.381, comfortably the best lap of the weekend.

The battle for second was closely fought though with Alberto Moncayo benefitting from a slipstream to sneak in front of Sergio Gadea in the closing seconds. Zarco was on a flyer behind him though and pipped him by the narrowest of margins, one thousandth of a second.

Gadea was the last man within a second of Terol in fourth while Vazquez couldn't live up to his promise from this morning, finishing in fifth place. Brno winner Sandro Cortese took sixth despite leading the session early on ahead of the second Aspar Aprilia of Hector Faubel with Jonas Folger the fastest of the Red Bull Ajo entries in eighth.

Teammate Danny Kent got as high as fourth at one stage but dropped back to tenth with Maverick Vinales just in front of him. The 16 year old sensation had a quiet day by his high standards but can't be ruled out for a podium challenge as the weekend progresses.

Danny Webb gave Mahindra plenty of cause for optimism with 11th place while Harry Stafford and Taylor Mackenzie finished the session line astern in 24th and 25th.
