Best starter bike is the Aprilia 660 RS, but given how hard it is to get European bikes repaired I would say Yamaha. I had a 600 Yamaha back in the 1990s.
Then a BMW and a Harley until a drunk driver nearly killed me. I’m lucky I can still walk. It’s been sports cars since then.

You need to learn how to REALLY ride a bike before that!
