Well,
I had both. A big scooter and a big bike (meaning something 400cc or bigger).
If I were living in a city, there's no doubt it would have to be a scooter. Just so convenient. The space inside the seat or on the floor for groceries and the likes. No speed changes to deal with in a stop'n'go situation between red lights.
But...
I used to live in a city, and the scooter made sense... but it was never ... fun.
Nw I live in the countryside, and although a scooter is still the norm around here, I just love my Triumph. I am a motorcycle guy at heart, not a scooter guy.
I had the Ninja 650R, which had almost the same engine as the Vulcan S, and it was sweet. I had a custom pipe fitted to a second hand Akrapovic can, and it sounded amazing!
If you're stuck in a city, the scooter makes sense.
If you're going around the country, than, for me, there's nothing else than a motorbike.
Best of both worlds?
Keep the Vulcan at home. And get a cheap 50cc second hand scooter that stays in the city, for running errands. Heck, even a bicycle would do for running around the city most of the time.
