Three-time MotoGP champion Jorge Lorenzo has confirmed he will retire after this weekend's season-ending race in Valencia.
Lorenzo secured the premier-class title in 2010, 2012 and 2015.
His third title was secured in the only season that Marc Marquez has not been crowned champion since debuting in MotoGP in 2013.
Lorenzo joined Marquez at Honda for 2019 in a blockbuster line-up, but the 32-year-old has suffered a disappointing season, marred by injuries.
He will retire with only five riders having taken more grand prix race wins, with 68 victories to his name before his final outing.
Lorenzo told reporters in Valencia: "I've always thought there are four significant days in the life of a rider - the first one is when it's your first race, the second one is your first win, then your first world championship - not everyone can win the world championship, but some of us made it. And then the day you retire.
"As you all imagine here, I'm here to announce that this day has arrived for me.
"This will be my last race in MotoGP and at the end of the race I will retire as a professional racer."
