So I had a 2011 Ninja 250r for around 3,000 miles, then someone hit the bike in a parking lot... around that time I had felt I needed more power, and wanted something bigger so that I could have that punch of power IF and only if I need it. So I test road my buddys Yamaha R6, super super fun, BUT I knew right then and there it wasn't for me, it WANTED to go faster, it WANTED speed and if you didn't give it up it just would putt putt around, so then I test road my buddies Ninja 650r... by the next week I had bought a 650r. It doesn't have that racing position, that some people love it had a more up right cruiser style position with a sport look and had all the speed I'd ever want, been riding for about 2 days now and I love my bike, very happy I didn't get a R6 but people will swear to the heavens there better so all on prefrence, I'd recommend riding both to see what you like but yea the step up really wasn't that hard, just respect the bike. (I don't know if I mentioned it I have 2012 ninja 650r no real mods out for it thou, like sliders or even seat cowls that I can find for that matter.) Anyways best of luck!
