hey mate good to see more bikers, right as you have said you need to take your cbt which is normally around a 6 hour day in which you discuss clothing, road signs, how to safely ride a bike and plenty of other things, if you already have a helmet, jacket and gloves then this is handy but if not most riding schools will supply you with them, they will then take you out in the van to a location to speak to you again and show you the controls of the bike, now are you intending on riding a bigger bike and if so a 125cc geared bike is what you need to ride to get used to the extra power and gears, the next thing they will do is to let you ride around in the area you are in and do various manovers for example emergency stop, u-turn, figure of 8 and other manovers, they will then once satisfied with everyone take you out on the road (normally two per instructor) you will be given an intercom system to put into your ear and can only listern to the instructor, they will then take you to various places and you will do manovers again, its virtually pass proof, even some people falling off have passed, now providing you are over 17 as you have said you have a driving liecence you can now ride up to a 125cc motorcycle, if you ride a 50cc you DO NOT have to display l's plates and insurance providing can take pillions but if you chose to ride any thing bigger you must display l's and cannot take a pillion. With regard to what is next you can then take lessons or if you are 21+ you can take the Direct Acces test which intitles you ride any bike when finished, what i would suggest doing if under the age of 21 is completing your theroy test for the motorbike and then booking a test and tying in your lessons to go up to you test, i would also suggest doing this in 2007 as in 2008 new rules are being imposed and if you are under 21 these will effect you, also if you are under 21 you will be restricted to 33hp for 2 years. Good luck with everything and if you need to know any more feel free to pm me.
