l already have a car licence.

http://direct.gov.uk/en/Motoring/Motoringtransactions/DG_10032681

it will be £17.50 to update your existing licence to include motorcycles

on avg cost about 500 600 to do a das course if you are over 21

about £18 to get it added to your car licence..

It depends on how much experience u have, what size motorcycle u r planning to ride.

if u already know how to ride a motorcycle with gears, then DAS (Direct Access) will entitle u to ride any size motorcycle, u will need to complete the following;

A CBT training: takes 1 day at the cost of around £100.

Motorcycle theory test: £30

Practical test: if u have ur own motorcycle, which must be a 500cc or over with insurance an a valid road tax. Then u will only pay the test fee which is £80.

If u do not have ur own bike or dont have sufficient experience, u will need to get DAS training which would include the CBT, theory test, practical test & the bike hire.

Minimum DAS training is 3 days. Which costs around £350.

Good luck if u decide to do ur bike license.
