The Superbike World Championship 2011 comes to an end after this last round in Portimao. Haga couldn't fully express himself due to particular track conditions that led him to some lack of grip. He's been protagonist of two great starts but he had to defend himself until the chequered flag closing the races with a 15th and an 11th place. The japanese rider leaves the Championship hitting a 8th place on general ranking, after 2 seconds and 2 third placings.
