Paul Aylward, who has since retired from the sport, and wife Lynn recently visited the Air Ambulance base to thank Dr Mamoun Abu-Habsa and Jez Loseby, and donated more than £1,000 to the charity.
He said: “It was absolutely brilliant to meet and personally thank them.
“I’m so grateful and very aware that without the professional expertise and decision making of Mamoun and Jez my situation would be very different.
“I feel incredibly lucky that I can lead a near normal life. The support I’ve had from my wife and people around me has been unbelievable.”
Paul was competing in a Southern Motocross meeting when he lost control of his bike and crashed during qualifying, suffering critical head and chest injuries.
Dr Abu-Habsa and critical care paramedic Dr Loseby arrived within minutes, carried out emergency life-saving treatment at the track and performed advanced medical procedures usually performed only in hospital.
Paul was then airlifted to Royal London Hospital by the Kent, Surrey and Sussex Air Ambulance unit and Lynn was rushed to the major trauma centre under police escort.
In March, he was awarded the Southern Motocross Clubman of the Year in recognition of his amazing determination to recover from his injuries.
