KTM's Miguel Oliveira won the final race of the 600cc Honda Moto2 era, following a late fall for leader Alex Marquez in a wet Valencia Grand Prix.
Marquez took over at the head of the pack on six and held a two-second lead at one stage before tipping off of his Marc VDS on lap 15, allowing Oliveira to ease to his third win of the year.
Xavier Vierge muscled his Intact GP Kalex into the lead on the run to Turn 1 at the start, while poleman Luca Marini's season lasted just one further corner, as he was taken out in a collision involving Joan Mir [Marc VDS] and Pons' Lorenzo Baldassarri.
New world champion Francesco Bagnaia also got caught up in the incident with his VR46 teammate, though stayed mounted and rejoined 18th.
Vierge's run at the front only lasted until Turn 12, when Italtrans' Mattia Pasini moved through before Oliveira followed suit on the pair of them on the run into Turn 1 at the start of lap two.
By lap four, Marquez had picked his way through on Pasini and Vierge, and quickly set about wiping out Oliveira's one-second advantage at the front of the pack.
A small error exiting the final corner from Oliveira gave Marquez the run he needed to draft past into the first turn at the start of lap six, and soon began to ease away to a two-second lead.
Vierge's charge for the podium ended on the eleventh h=tour, when he crashed at Turn 12, releasing CGBM Evolution rider Iker Lecuona into third.
Marquez's hopes of ending his drought came to an end of lap 15, the Spaniard crashing going through the final corner.
But such was Marquez's lead, he was able to rejoin in third, albeit 18 seconds adrift of new leader Oliveira, who in turn now had seven seconds over Lecuona.
Oliveira came under no pressure as the race reached its conclusion, the MotoGP-bound Portuguese rider easing to victory 11 seconds ahead of Lecuona.
Marquez remained in third after his tumble, while Pasini and Remy Gardner [Tech3] rounded out the top five.
Gardner snatched fifth away late on from the recovering Fabio Quartararo, who was forced to start last after stalling his Speed Up before the warm-up lap.
Marcel Schrotter [Intact GP] shadowed Quartararo home in sixth, while Augusto Fernandez [Pons], the second Italtrans of Andrea Locatelli and Tasca's Simone Corsi completed the top 10.
Bagnaia recovered to 14th following his lap one tangle, with SAG's Jesko Raffin taking the last point, while Dominique Aegerter [Kiefer], Honda Team Asia's Tetsuta Nagashima and NTS' Steve Oddendaal split Bagnaia and Corsi.
Only 20 riders made the finish, with the crash list including Lecuona's teammate Sam Lowes, Brad Binder on the second Ajo KTM and Gresini's Jorge Navarro.
