Hi, I would like to take a motorcycle test (for any kind of motorcycle - not only 50cc or 125+ cc) and based in the UK. could someone please tell me the actions I have to take and how much would it cost me in total (minimum lessons + exam fees + extras?) - I already have an EU car driving license, so would this sort-of-upgrade be easier to do (e.g. cheaper, or not having to take the theory, etc?) Please enlight me !
