Hey been riding for a long time I have a 125 Kawasaki 2007 modle I'm looking to move up a little now and also looking for my 1st sports bike but not too fast or too much power what should I go with

I would recommend one of the naked 600 series bikes like a z650 or a sv600. Both are very capable having fun on but remain comfortable for ride position

If you have rode for a long time I would start with a 600cc. Has enough power but not to much. The 600 will also be worth the money you spend to. I wish I would've done that instead of getting a 250 for my first one haha.
