A good friend of mine is selling his 2006 YZ250F in excellent condition for $2k. I've been riding road bikes for years, but I've never even thrown a leg over a dirt bike. If I got it, it would be to do some rides on the desert trails here in Tucson. I'm not planning on racing it or taking it off jumps, I'm just looking for something that will be fun. I'm also a mountain biker (bicycle) so I have a good level of technical skills in the tough stuff. What worries me is that I've heard the YZ250F is a purebred race bike, and using it for anything other than all-out MX racing is a waste. Why is that? Is it because the maintenance is high? I don't mind changing the oil and rings, in fact I love doing that type of maintenance. But what worries me is when I watch some of the reviews for this bike, they say, "This bike will last you a full season" Uh... what exactly does that mean, that the bike will seize up and die after a season? If I buy it with the intention of doing trails riding, nothing too extreme, and keep up on the maintenance, how long will this bike last me? Thanks!
