Italian Cudicini was seriously injured in November 2009 when his BMW bike collided with a car on his way to Spurs' training ground in Essex.
He admitted: "I've never been on a motorbike since then. I don't know if I will ever ride a motorbike again.
"At the moment I'm just trying to concentrate on my career and be as healthy as possible. What happens in the future, I don't know."
