how do i get a motobike license? (UK)?

At 16 you can only ride a moped. At 17, you can have a "medium-sized" motorbike up to 33 bhp. Only at 21, or two years after having passed the test on a "medium-sized" motorbike, are you free to ride any motorbike. I know it sounds restrictive but so many young people have accidents on motorbikes. I had a friend many years ago who got killed on one. It also makes insurance expensive - so many young people have accidents on or in ANY kind of motor vehicle that insurance companies charge accordingly.

It's an interesting question of law and politics - how far should law go in restricting what we do to protect us from ourselves and each other? Another little fact - the UK has a penalty points system, and motoring offences get points on your licence. The standard punishment for going over the speed limit and getting caught by a speed camera, for example, is £100 fixed penalty and 3 points. Get 12 points within 3 years and you're automatically banned from driving for however long the court says, 6 months at least. But if you get 6 points within two years of passing the test, your licence is totally revoked and you have to pass the test again. I'm sure you want to be responsible and enjoy riding a motorbike safely but the law has to be the same for everyone, taking into account irresponsible bikers.

(Of course irresponsibility doesn't necessarily have anything to do with age... my Mum, who worked as a secretary, had a boss who was very fond of long alcoholic lunches, and she was forever having to make excuses to anyone who wanted to speak to him on the phone in the afternoon. Her address book contained all his favourite Indian restaurants so if it was really urgent she could ring up and tell him "get back here NOW!" His fun was cut short when he eventually got caught for drunk driving and banned. You might be thinking "what about his mobile" but this was 30-40 years ago when mobile phones didn't exist. I'm 48 and Mum is 75 now.)

When it is legal to start learning on public roads is the same age as when you can have a licence (in the UK we don't use the American spelling "license"). You need to apply for a provisional licence first and you can get a form D1 for that from any main post office. Or you can do it online at https://www.gov.uk/apply-first-provisional-driving... Once you have a provisional licence, you can start lessons. The driving test is a stiff one - I've only done it in a car and passed second time, which is about normal.

I think you will have to contain your enthusiasm for a while :(

The only licence you can get at 16 is for a moped that isn't allowed on motorways. You'll have to be 17 to drive something on a motorway and L plates aren't allowed on motorways.
