If you're looking for city ride, I think both model suit you well. Not sure about the 390, I owned the cb250r

For the past 2 years I've been riding the 250r, there's no major issue, just wear and tear. I think it's very easy to identify what need to change, therefore it's reliable enough for me.

Oh and if you're still looking for the bike, I'm letting go my bike btw. Let me know if you're interested. You can pm me for more info.
