This Gixer thou I'm buying is just under 3 years old and on an NI plate. In NI bikes don't need an MOT for 4 years from date of first registration. I need to get it registered over here but I want to keep the NI plate. Questions: How do I go about it? Do I need to get an MOT regardless of age? Do I have to tax it for a year when doing the registration thing, or can I opt for 6 months? How much is this lot going to cost me?
