In the season finale at Portimao, in the second and final race of the season of 2011, Marco Melandri and Eugene Laverty took positions one and two respectively on the Yamaha R1. Earlier in the year, Yamaha announced its intention to pull out of World Superbikes and this 1-2 effort is a fitting finale for the Japanese manufacturer. Third place in the race went to Jonathan Rea on the Honda CBR1000RR, like in the first race.
Earlier in the first race Carlos Checa on the Ducati 1198 clinched victory ahead of Sylvain Guintoli also on a Ducati 1198. The third position was clinched by Jonathan Rea on the Honda CBR 1000RR Fireblade.
