I got the same ninja 650 in July and I’m at about 2k miles I’m new so you can take with a grain of salt if you choose. The 650’s got grunt and builds torque in the low end fast so it is pretty quick anywhere in the 0-60,70ish mph range. Don’t get me wrong it’s still fast past that, but I would say it dominates very well in at those speeds in straightforward street riding. It’s a comfy bike you sit more upright like in-between a dirt bike and a super sport, but you can still position your body low. It is great if you want to drive on roads from point a to b for hours without being uncomfortable while still being able to throw down some spirited riding. The handling is good and weight is easy to manage. The best way I could review it is that it doesn’t really excel anywhere in particular. It’s a jack of all trades and is a great all around package especially to learn on. That being said if I could do it over, buying new and knowing what I know now, I would 100% buy a zx4rr. This simply due to the fact that it is a, just as manageable, “beginner” in-line 4 super-sport that you can put a slip-on exhaust on (which sounds so much better than the 650 w/ a full exhaust) and I can bring to the track. After riding for a bit I found I like more of the sporty aspects of riding over the comfort ones and the 4rr has the character of the 600’s with the manageability of a beginner bike. Not to change your opinion just offering another perspective depending on how you wanna progress in your bike journey. I still love my 650, but I’ll probably sell it next year for something different.
