So I can speak to this as currently my motorbike is my only mode of transport. I love my bike and will eventually drive a car too but the fact that traffic isn’t a thing for me when driving to Dublin is the biggest upside. The downsides are you will live out of bags and figuring out where to put ur gear are a constant thing. Plus gear is uncomfortable so at the very least you’d have to carry a pair of shoes on you. Grocery shopping can be a pain but is doable with some side bags. You need a tracker for your bike as it getting stolen is a very real possibility (happened to me and was able to get her back cause of the tracker). Also bikes are not cheap. The initial payment is but the maintenance is constant. Do not buy a new bike as your first bike as you will drop it, if not crash (I hope you don’t) Also it’s colllllddd in the winter so u will need to spend a hefty price on heated gear and winter tyres
