Hi im from swindon theres a place at blunston stadium they let you have a hour training free for cbt it called a van van the bike you use there if you do full test you can ride any cc but if you do a cbt its 125 or smaller expect cheeper insurance. Theres a big diffrence in bikes but the driving is the same ish. If you buy second hand ask for it to be booked in a garage that day to let you know what could be wrong with it they might miss somethings expect to have a few hundred £ in case somthing gos wrong with any bike water might get in somthing or a pot hole could do something wrong.the best advice i can give it get some good outfit case you do come off. Good luck (and breath when reading my comments my grammer ant not no good ) full stop ....
