Miguel Oliveira has out-dragged Luca Marini to the finish line at Brno to take over the Moto2 championship lead from the final podium finisher, Francesco Bagnaia.

The race came down to a battle between those three and Lorenzo Baldassarri, and Oliveira led into the final lap only to run wide at Turn 1 and let Marini through.

The Portuguese rider re-passed Marini at Turn 11, only to come under attack at the penultimate corner.

Oliveira, however, managed to hang on the outside of the Italian which gave him the inside line when the track switched back for Turn 14.

He rode his Red Bull KTM Ajo bike on to a win of just 0.070s, while Baldassarri was only 0.745s away from the leader in fourth.

Remy Gardner (Tech3 Racing) did not complete the first lap after a multi-rider crash at Turn 5, but all three men walked away.

Fabio Di Giannantonio became a first-time race winner in Moto3 when he passed Czech Jakub Kornfeil on the final lap then held off Aron Canet.

Kristoffersson dominated his semi-final after sitting just ninth overnight, before heading all six laps of the final.

Mattias Ekstrom made the best start in the final, but found his way blocked by Kristoffersson and Timmy Hansen into the first corner.

A mistake from Hansen further around the opening lap cost him any chance of victory, and bunched up the chasing pack behind.

Kristoffersson took his joker lap on Lap 5, holding the lead to the finish.

Hansen was second with Sebastien Loeb crossing the line to take third.

Loheac in France will host the next round of the World RX season on September 1-2.
