Hmmmmmmmmm....
The DirectGov website says different:
http://www.direct.gov.uk/en/Motoring/Le ... DG_4022568
I quote:
"Full motorcycle licence
The practical test must be taken on a bike of between 75 cc and 125 cc. There are two types of full motorcycle licence:
* a light motorcycle licence (A1), which restricts riders to any bike up to 125 cc and a power output of 11 kW
* a standard motorcycle licence (A), is obtained if the practical test is taken on a bike of over 120 cc but not more than 125 cc and capable of at least 100 kilometres per hour (km/h per hour)..
After passing the standard motorcycle practical test, you will be restricted for two years to riding a bike of up to 25 kW and a power/weight ratio not exceeding 0.16 kW/kg. After this you may ride any size of bike."
I have a standard motorcycle licence which I passed just over a year ago when I was 18 so I dont even have to wait till my 21st, I can ride anything around this time next year!
