Background: Marc Marquez Alenta (born 17 February 1993) is a Spanish Grand Prix motorcycle road racer and four-time MotoGP world champion. Marquez races for Honda's factory team since his MotoGP debut in 2013. Nicknamed the "Ant of Cervera", he is one of four riders to have won world championship titles in three different categories, after Mike Hailwood, Phil Read and Valentino Rossi. Marquez won the 2010 125cc World Championship, the 2012 Moto2 World Championship, and the 2013, 2014, 2016 and 2017 MotoGP World Championships.
Context: Marquez moved into the Moto2 class for 2011 - the first of an expected two-year deal - as the sole rider of the new team Monlau Competicion, run by his manager Emilio Alzamora. He finished 21st in Portugal, before taking his first victory in the class at the French Grand Prix. At his home race in Catalonia, Marquez finished second behind championship leader Stefan Bradl, before another fall at the Silverstone, having started from his first Moto2 pole position. With Bradl taking his fourth victory in the first six races, Marquez trailed him by 82 points at the end of the weekend. Marquez made a mid-season surge up the championship standings, winning six of the next seven races to move within six points of Bradl in the championship standings.  In the Japanese Grand Prix, Marquez took his seventh pole position of the season but finished second to Andrea Iannone, but that finish combined with a fourth place for Bradl, allowed Marquez to take the championship lead by a point. At the Australian Grand Prix, Marquez was involved in an incident with Ratthapark Wilairot during free practice; Marquez crashed into the back of Wilairot after the session had been concluded, and for riding in an "irresponsible manner", was given a one-minute time penalty onto his qualifying time. The penalty ensured Marquez would start the race from last on the grid, but he made his way through the field and eventually finished the race in third place.  Prior to the Malaysian Grand Prix, Marquez confirmed that he would remain in Moto2 for the 2012 season, after rumours of a move into the MotoGP class. Marquez's race weekend was hampered in the opening minutes of the first free practice session, as he crashed on a damp patch of asphalt. After sitting out two further practice sessions, Marquez completed two laps in the qualifying session, but his times were only good enough for 36th on the grid. He did not start the race, as he failed a medical examination prior to the warm-up on race morning. Marquez attended the final race of the season in Valencia, in the hope of being fit to compete, but withdrew due to his continued vision problems, giving Bradl the title.  In 2012, Marquez won the Moto2 championship title after a season-long battle with fellow Spanish rider Pol Espargaro; a third-place finish for Marquez at the Australian Grand Prix - despite a win for Espargaro - was enough to give him his second world title before moving into the premier class for the 2013 season. He took his last victory in the class at the Valencian Grand Prix, the last event of the season, despite starting from 33rd on the grid. This performance, which implied overtaking 20 bikes on the first lap alone, meant the biggest comeback in the sport's history. He finished the season with nine race wins, setting a record for the class that still stands. Marquez's result was enough to give Suter the constructors' title for the class.
