KTM Ajo’s Jose Antonio Rueda showcased a dominant performance to seal victory in the Czech Moto3 race and extend his championship lead.
The Spanish rider led from start to finish to record his seventh race win of the campaign by over three seconds.
The championship leader got the best start from second and passed polesitter Guido Pini into Turn 1.
Maximo Quiles also made a good start from the second row of the grid, and used his momentum to pass Pini to move into second place.
Further down the order, David Munoz had been relegated to the back of the grid due to irresponsible riding in practice, but progressed to 12th by the end of the first lap.
2020 Czech Moto3 winner Dennis Foggia also had a strong start to the race and made a move on team-mate Quiles to take second.

The move allowed the top five to open a small gap, with Adrian Fernandez moving into the podium places.
Quiles set the fastest lap of the race on Lap 8, which forced Piqueras to make a move on Fernandez to maintain his position over the rookie.

Behind the Spanish rider, Quiles took charge of the chasing group as he passed team-mate Foggia to lead the pack of six riders fighting for second.
The Italian waited for a lap before responding to his team-mate at Turn 3, as Foggia moved back into second.
The two Aspar riders continued their duel, but Munoz, Piqueras and Fernandez were all lurking in the background on the final two laps.

The battles continued through to the final corner, with Quiles looking vulnerable as both Munoz and Piqueras overtook the rookie with just a few corners remaining.
