It was a special day for the Marquez family as brothers Marc and Alex both finished the day with plenty to celebrate after a memorable day at the Grand Prix of Valencia.
Big brother Marc had already claimed the MotoGP world title earlier in the season, and he rounded out the season by claiming his 13th MotoGP victory of the campaign, pulling clear of Valentino Rossi in the latter stages of the race to break MotoGP legend Mick Doohan's record for the most race wins in a season.
Rossi took second place in the race to secure second in the MotoGP championship standings, with Marquez's Repsol Honda team-mate Dani Pedrosa taking third.
In Moto3, Marc's little brother Alex Marquez clinched the world championship after a dramatic final race of the season.
Marquez's nearest rival, Australian Jack Miller, did everything he could to pip the Spanish racer to the title, winning the race after overhauling Isaac Vinales in the closing stages.
But Marquez needed a third-place finish to secure the world title, regardless of Miller's performance, and the Honda rider did just that, holding off a late charge from Britain's Danny Kent to claim the world title.
The Moto2 race saw drama early on as the two riders battling for second place in the championship collided.
Maverick Vinales went into a left hander far too hot, and crashed into the back of Mika Kallio, taking the pair of them out of the race.
The crash didn't do Vinales any favours, however, with both riders' DNFs securing second place in the championship for Kallio.
Up front, world champion Tito Rabat looked set for victory after holding off Thomas Luthi, but lost power coming out of the final corner, allowing the Swiss rider to steal the victory with just yards to go.
