Spanish rider Jorge Lorenzo became a three-time MotoGP world champion in the season finale at Valencia. Motorsport.com looks at his career achievements since his grand prix debut back in 2002:
2002: Grand Prix debut in 125cc class
Jorge Lorenzo made his Grand Prix racing debut in the 125cc category in 2002 with Derbi Racing (pictured here alongside teammate Youichi Ui). He finished 21st in his rookie season, and then came 12th and fourth in the two subsequent seasons before moving to the 250cc category for 2005.
2006: 250cc World Champion
Lorenzo finished fifth in the standings in his first year in the intermediate class, before clinching his first world championship in 2006 with the Fortuna Aprilia team. He notched up 11 podiums, including eight wins, beating Andrea Dovizioso in the standings by 17 points. Here, he joins 2006 MotoGP champion Nicky Hayden and 125cc winner Alvaro Bautista.
2007: Double 250cc champion
A year after his first 250cc title, Lorenzo doubled up in 2007, winning his second championship for Fortuna Aprilia with a total of 12 podiums, including nine wins, to his name. Dovizioso was his nearest challenger again, albeit 52 points back.
2008: Testing with Yamaha
After his two title-winning seasons, Lorenzo was ready to move up the ladder into the MotoGP class, getting his first taste of the Yamaha YZR-M1 in post-season testing at Valencia.
2008: MotoGP debut in Qatar
Lorenzo made a dream premier class debut in 2008 with Yamaha in the Qatar Grand Prix, where the Spaniard took pole, finishing second in the race behind Casey Stoner.
2008: First MotoGP win in Portugal
In only his third MotoGP race, Lorenzo got his maiden premier class win starting from pole in the 2008 Portuguese Grand Prix. He went on to finish fourth in the standings that year, as teammate Valentino Rossi took the title.
2010: Maiden MotoGP title
After coming off second-best in a bitter scrap with Rossi for the title in 2009, Lorenzo took his first crown in his third year with Yamaha, albeit helped by Rossi being ruled out of action by a broken leg after a crash at Mugello.
2010: Champion celebrations!
On the road to his first MotoGP title, Lorenzo took no fewer than 16 podium finishes, including nine wins, to defeat Honda's Dani Pedrosa, who missed races due to a fractured collarbone, by an overwhelming 138 points.
2012: Two-time MotoGP world champion
Casey Stoner and Honda dominated the final year of 800cc competition in 2011, Lorenzo missing the final races due to a finger injury, but the Spaniard returning to winning ways in 2012 with a second MotoGP title in three years.
2012: A champion's ride!
On his way to the 2012 title, Lorenzo once again notched up 16 podiums, including six wins, to defeat Honda's Pedrosa by a narrower margin of 18 points with one round to spare.
2015: Becoming a three-time MotoGP champion
Lorenzo lost out in a final-race shootout to Marc Marquez in 2013, before the Honda rider dominated in 2014. But with the 2015 season being a straight fight between Lorenzo and teammate Rossi, it was the former who ultimately prevailed by five points after another tense showdown at Valencia.
