The CBR 250 should last at least as long as the Ninja with good maintenance practices.

Using a Scottoiler or other auto chain luber can extend chain life 3 to 5 times - really.

Learning about your bike and doing the basic maintenance on it yourself can save you a ton of money. I think you stated the tire cost too high. This light of bike and selecting touring tires should extend life well, well beyond 15K miles. Learn to change them yourself, it's not all that difficult with the tubeless tires.

As stated, nothing is cheaper than using and maintaining what you already have. The CBR is a nice bike and I'd consider one if I was buying new. I was really suprised when I saw it at the motorcycle show priced directly in line with the Ninja. I expected the usual too-proud Honda price would be about $5K.
