At a press conference he explained the reasons for the press, in a "letter" Spanish pilot fonsi Nieto told fans he hung the helmet as a result of a badly healed injury suffered in Indianapolis, Indiana in August 2010.
Letter to the fans:
"As you all know I was registered and ready to participate in the Moto2 2011 world but after try all winter to train and to think so much I decided to end my career." It's been a decision very difficult for me, because my cousins (Pablo and Gelete, owners of the G22 Racing Team) and my personal sponsor Confremar I was in a privileged position in a time when it is difficult for everyone.
Unfortunately for me, my foot is not 100% yet and we have not been able to follow as I did during my career to run at higher levels, the reimbursement of the efforts of my team and all those who support and supported me: why I announced my retirement from competition?.
A retreat that causes me pain without end, because the moto has been and always will be my life, but I am still happy, happy for what this world gave me sporting satisfactions and human terms. I have lived a very special moment that I've always wanted to see, I have known and worked with wonderful people that made this possible, living as I want as a child when he wanted to be a pilot.
So let me remind all those who helped me, even if the list is very long since the mini, with Gonzalo Arribas, TMR and Aspar, a great master who allowed me to have my first podium, my first victory and the second in the Championship (250cc 2002 season). I also thank the people with whom I have worked on Superbike I welcomed with great affection, Guido Pagani and Kawasaki, that also allowed me a career in MotoGP, but Francis Batta, and Suzuki, alongside whom I won my first Superbike career...
I must thank Luis Guerra, my cousins, family Ezpeleta, the IRTA, Dorna, my sponsors, my family has always supported me from the first to the last day of my career, my girlfriend Dawn, my fans who have supported me in the difficult moments of my career, but also to Dr. Villamor.?
I can not forget my friends who have followed me, Medica Quique, Javi, Andoni, the press, my fan club are by far the best fans in the world. Now I will continue to be part of this world living from another perspective, because the two wheels are important in my life. “
