Andrea Iannone has won the 125cc Catalunya Grand Prix after Julian Simon threw the win away by celebrating victory a lap too soon.
The two Aprilia riders exchanged the lead countless of times during the 22-lap race,
but Spaniard Simon managed to open a 0.3s gap over the Italian by the beginning of the penultimate lap.
Just as the riders were starting the final lap, Aspar's Simon began celebrating in front of his home crowd, while his crew was frantically pointing at the pit board indicating one lap was still to go, and Italian Iannone (Team I.S.P.A.) was taking advantage of the mishap.
But the two riders had been just ahead (1.7s) of a group of four other riders fighting for the last podium position. Simon was thus swallowed by that group, and took some big risks when trying to salvage at least a place in the top three.
In the end he did manage to take the lead in the championship by ending up fourth, beaten by team-mate Sergio Gadea by just 0.001s and the Jack&Jones Aprilia of Nicolas Terol who took second, 2.2s behind Iannone.
Red Bull KTM's Marc Marquez classified fifth, just two hundredths behind Simon.
Jonas Folger (I.S.P.A. Aprilia) finished sixth, ahead of Stefan Bradl (Kiefer Aprilia), Bradley Smith (Aspar Aprilia), Sandro Cortese (Ajo Derbi), and Randy Krummenacher (Degraaf Aprilia) completing the top ten.
