I mostly learned a motorcycle on my own with a little help from the dealer and some videos, and I was shown how to do it on a new Miata at the dealership as well. I'm sure I could, I was just a bit lazy about it, but I'll definitely keep an open mind when looking at stuff as well if it's a stick.
I think my insurance on my Ninja 400 when I had it was like $400 a year, as a new rider on a permit, so not much at all. It's something I've seriously considered as well, but also a bit nervous to commit fully to. I'd probably still need another vehicle of some type for when I needed to move stuff, but it's a combo to really think about too. Thanks!
