Ok, what would be a reasonable price for like a 2008-2009 (newer gen) Ninja 250 as a beginner bike? Im looking to buy one this summer when i get home and I'm new to the bike world, so any advice will help me a lot!
Search your area's Craigslist. That will give you an idea of the "market" price in your area. See what the high price is and what the low price is and note the mileage and condition. You may find that a low mileage one made within the past few years is too much, or when you go to look in the summer you'll find one that's priced low and you know you could be getting a deal. Keep in mind that prices will rise a little when it warms up as people are more eager to buy, compared to the winter.
