We've had a few calls recently about which licence you need to ride a Royal Enfield in Ireland. So we have added a page to this site explaining everything you need to know. See http://www.royalenfield.ie/rider-training-bike-lessons-ireland
In a nutshell, a Category A2 Motorcycle Licence is sufficient for all current Royal Enfield models. However, if you are just starting out, we recommend you go straight for the Category A Licence which will allow you to ride any motorcycle of any size of any power.
Any further questions just give us a call.
