I was looking at a GSXR 600 but quickly realized it may be too much for right now, seeming that I am brand new to motorcycles. But was wondering how long how do people usually keep a Ninja 250 before moving up to a bigger engine? And if so what bike would be good to move up to after learning on a ninja 250? I was thinking of switching to the GSXR 600, R6, or CBR 600RR any suggestions?
