While Yamaha will look on with relish at the competition among the bikes, they can feel highly confident when it comes to the Quads; now fixed with a 750cc limit for the engines. Argentina boasts a plethora of extremely capable drivers in this discipline and at the top of the tree are the Patronelli brothers, Marcos and Alejandro, who have claimed the last two Dakars between them on their Yamaha YFM700Rs. It was the latter, Alejandro, who grasped the crown while nursing a hand injury this year as 2010 winner Marcos had to retire with physical problems. The older sibling (Alejandro) has notched seven stage victories in two years and the pair has yet to classify outside of the top two in their attempts at the Dakar. Following the Patronellis' is fellow countryman Tomas Maffei, also Yamaha Raptor mounted, and a stage conqueror back in January. Another stage victor from the previous Dakar is Czech veteran Josef Machacek, who will also roll into the Argentine capital. Among the Women's competition FIM Cross Country Rallies World Champion Camelia Liparoti will be aiming to better her previous finish of 10th. Yamaha owned eleven of the thirteen 2011 Quad stages with five different riders; anything approaching the same level of achievement will be outstanding.
