Dreamer, its medical reasons mate. I am able to take the test (Full car licence, over 21, etc) just other things are stopping me at present.

I have ridden a few bikes, such as a GSXR-1000 and R1 in the past. Had not much confidence on them, but was teaching myself to ride. Only covered about 200miles!! I did go to get my own bike, but the finance was rejected at the time (This would of made me get my licence if the finance was approved). Im gutted I never did the test anyway
