(CNN)Marc Marquez clinched his third MotoGP crown in dramatic fashion Sunday with victory in the Japanese round as closest title rivals Valentino Rossi and Jorge Lorenzo both crashed out.
The Repsol Honda rider has an unassailable 77-point lead over Rossi in the championship with three rounds still remaining after his triumph at Motegi, the home circuit for his team's manufacturer.
Italian legend Rossi had started from pole on his Movistar Yamaha and was involved in an exciting duel with Marquez until an early trip to the gravel ended his chances of a 10th world title.
