Valencia - Three-times MotoGP world champion Jorge Lorenzo, who suffered a fractured spine this season, said Thursday he would retire following the Valencia Grand Prix.
"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," Lorenzo said.
Lorenzo said that a series of spills earlier this season with Honda led him to consider retiring for the first time in his career.
He described how he was picking himself up off the gravel when he made a snap decision to quit the sport.
Later he had a rethink and returned to the circuit but reached a final decision after mature reflection.
