RGV 250, what’s she like?

hiho! so I’m new here…at least in the motorcycle forum and don’t even have a machine yet. it’s just that I want to buy one soon and I decided so slowly for the suzuki RGV 250 because I find the one of the optical ok etc. now my questions: how much can such a part cost? how much can it have down? is there such a thing as a wear and tear that you always have with a certain number of kilometers? does she have other problems? and especially the most important thing for me: how s does it look like care and follow-up costs? I’m not technically untalented but I have little idea in things like car and especially in things like motorcycle. would be nice if you could help me. thank you in advance, hekko!
