I bought this bike because you could get a new bike for half the cost of a larger new one. This was my first street bike. I didn't want a second hand sport style bike that was wheelied everywhere it was ridden. I wanted new, but did not want to take a loan out, or break my wallet. The bike is 4300 bucks Canadian. 5300 bucks out the door. I really enjoyed riding it.
This bike is absolutely awesome for the money. It has a good upright riding position (the handle bars are a good 2" above the triple tree). It's light and nimble, perfect for back road twisties. The bike also accelerates up to 100 km/hr with confidence. Hills are no problem for this bike either. The clutch and transmission are super smooth.
However, after about 110km/hr, forget about accelerating any more. You can go faster (if the wind is at your back) but you can't do it quickly (to get out of trouble). Example: When you're beside a semi, and the double lane is about to turn into a single lane. Do you accelerate at 100 km/hr past the semi or break hard for the driver tailgating you? I guess I could have been in the slow lane in the first place behind the semi, while it spits crap up at me. My point? It's a great bike for around town or a quick trip on the highway. But I commuted with it, and I was starting to run into these sorts of problems.
I now own a 2006 Honda CBR 600 F4I. I got it new, it was sitting in the show room for 2 years, and best of all I got it cheap. Still upright riding position, comfortable, and the power to get out of trouble (and twice the stopping power is a bonus too). I traded in my 250 Ninja and got the price I paid for it (before taxes of course).
The 2008 Ninja 250R is a great bike for the price and you will not be disappointed. It is arguably the best beginner bike you can buy. And best of all, you can't beat that price for a new bike. Tons of bike for the money! I got 200km's on 14 bucks @ $1.40 / L. My CBR is around 17 bucks / 200 kms.
Just don't commute with it on the highway. It's fine at first, gets up to the speed limit just fine, but not having that extra power with out wrenching the guts out of it (constant 10,000 RPM in top gear to pass) gets really old quick. I felt I was beating the crap out of the engine (and I didn't do it often). I also didn't like knowing I couldn't get out of trouble if the situation rose. I do not regret buying this bike at all, it held its value, and was easy/fun to ride. A perfect first street bike.
