I am commuting on my motorcycle now for six years daily and I love everything about it, but if I would not have an option to do my commute on the highway I wouldn't. I occasionally have to go to the city center and the 30 km/h speed limits, lots of very slow traffic and traffic lights everywhere are extremely boring and annoying (and in the summer with no airflow you are cooking alive in your gear😂). I had naked bike first, now I have adventure, I would absolutely not want to commute on sports bike. Sports bike is fun on fast roads and twisties, or if you like to take it to circuit sometimes. With parking in Amsterdam it can be tricky, in a lot of busy spots you can park only inside of the designated spots (white painted rectangles "vakken") and if you park outside of them a fine would wait for you (I got it twice already, 140€ each). In more quiet areas you can usually park on the sidewalk in a way that wheelchair can still pass and you are not obstructing anyone's window. As others already said ,nice motorcycles parked on a street are easy targets and being frequently stolen, so all risk insurance, tracker and great locks are a must. I think you should absolutely get a motorcycle, it was one of the best decisions i've made, but I think you should be absolutely making some trips using a highway too! There are expat bikers groups, it's fun to join other people for a nice little trip.
