Alright, folks, let’s talk about my little project – a 2007 Ninja 250. I’ve been tinkering with this thing for a while now, and I figured it’s time to share the whole journey with you all. And trust me, it’s been quite a ride.

I picked up this bad boy a couple of years back. It wasn’t in terrible shape, but it definitely needed some love. 18,500 miles on the clock, but a clean title, and I snagged it for 1,850 bucks. Seemed like a decent deal at the time. I mean, who doesn’t love a good project, right?
First off, this bike is a blast to ride. It’s light, it’s nimble, and it’s surprisingly forgiving when you twist that throttle. Perfect for a guy like me who just wants to enjoy the ride without needing a rocket between my legs. Plus, the gas mileage is killer. I’ve tracked it, and let me tell you, this thing sips fuel. Over the time I’ve been working on it I have recorded data from 25 vehicles, 388 fuel-ups and 73,308 miles of driving. Good stuff. I’m around 6 feet tall, 200 pounds, and I fit on this thing just fine.
Getting My Hands Dirty
Now, I’m no professional mechanic, but I’m not afraid to get my hands greasy. The first thing I did was give it a good once-over. Checked the fluids, the brakes, the usual stuff. The tires were decent, which was a plus. They still are very good, actually. But the chain and sprockets? Not so much. So, I got myself a new set. I decided to switch from 45t to 39t on the rear sprocket. I was thinking about selling it at that time, although it has 16.6k miles on it, I just kept upgrading it.
One thing I noticed about the Ninja 250 is that it has a big, easy-to-read speedometer. That’s a good thing, especially for newer riders. And it’s got a gas gauge, which is even better. No guessing games about when you’re gonna run out of fuel. Engine temps? Honestly, not something I worry about too much on this bike. It’s a 250, not a superbike, you know?
The Long Haul
- Change the oil: This is a no-brainer. Regular oil changes are the lifeblood of any engine.
- New spark plugs: Gotta keep that combustion going strong.
- Cleaned the air filter: A clean filter means better airflow, and better airflow means better performance.
- Adjusted the valves: This was a bit more involved, but it’s important for keeping the engine running smoothly.
I’ve put a decent amount of miles on it since I got it. I’ve heard people say that these little 250s might not last past 35,000 miles without some major work. But hey, I’m not too worried. I enjoy taking care of it, and it’s been reliable so far.

So, that’s my story with the 2007 Ninja 250. It’s been a fun, sometimes challenging, but always rewarding experience. If you’re looking for a fun, affordable, and relatively easy-to-maintain bike, I’d definitely recommend giving one of these a look. Just be prepared to put in a little elbow grease every now and then.
