luck, he also suffered a wrist injury midseason, which added to his woes. In the final third of a memorable season, the M1's problems were virtually eradicated, and Valentino Rossi turned in a string of performances that would close down a large points gap on Championship leader Nicky Hayden aboard the Honda RC211V. It was only in the final race of the season that the M1 and Valentino Rossi were beaten by just five points and Yamaha relinquished the Championship back to Honda in the hands of Nicky Hayden, who only won two races that season. Hayden would later state that Rossi deserved to be the champion, but luck and DNFs cost him the championship. Valentino Rossi would win 5 races in 2006 to Nicky Hayden's 2, a fact that was well played during the offseason. 2007 Regulations again changed for the 2007 seasonwith the capacity of MotoGP machines reduced to 800 cc in an effort by the FIM to reduce the ever-increasing speeds of the 990 cc bikes (capable of well in excess of 210 mph (340 km/h)); therefore the YZR-M1 would continue in 2007 in 800 cc form. In post-2006 and in 2007 pre-season testing, the new 800 cc equipped YZR-M1 (along with other 800 cc MotoGP bikes) has been paradoxically quicker straight out of the box than the 990 cc version of the M1. This is by virtue of later, harder braking, quicker handling, higher corner speeds, and more controllable traction, and as the 2007 season got underway, the 800 cc YZR-M1 was expected to get quicker as its development continued. The chatter that plagued the early 2006 YZR-M1 has been eliminated in the switch to 800 cc. While the main sponsor for the Official Factory Yamaha Team switched from Camel with their distinctive yellow and blue livery, to that of the Italian Motor Manufacturer Fiat. The team ran initially in a blue and white colour scheme and hinted at the unusual intention of running a variety of colour schemes throughout the season. Casey Stoner won the 2007 Championship with the factory Ducati. 2008 Rossi won the 2008 Championship, by a record margin and dominated podium finishes all season. Teammate Jorge Lorenzo managed a first-ever Rookie win on the M1 at the Portuguese GP, and had 6 podium finishes. 2013 For 2013 season, maximum engine capacity was increased to , with a limit of 4 cylinders and
