You have to do a cbt first which is £105
then have to book a theory test and pass that
Aftr your cbt he school will asses you and advise how many lessons they think you need, then when your ready they book you in for a mod 1, which is like a course in a training ground, then if you pass that they book you in on mod 2 which is a 40m ride.

You can take your test on a 125cc bike but your restriced to 33hp for two years, you can have any size bike you want aslong as its gt the restriction, so a gsxr600 could be restriced for ya..
