I have a 2007 Baja X250 motorcycle and absolutely love it. All I have done to it is general maintenance and have never had a problem with it, and no I'm not a dealer, just an average Joe that likes riding enduro dirt bikes, not full race bikes.
This is the most poorly made bike. When I was doing a chain adjustment, both the nuts got stripped.
On the way home, my kick stand broke, causing the bike to fall (on a trailer) on a main road.
This bike is very cheap. When riding, the throttle cable snapped (I was going half throttle). I had to walk the over 200 pound bike over hills for about 1 mile. Try your best not to get this bike, but if you do, carry an extra throttle cable and clutch cable.
I paid $1200 for my X-250, and for the money it's a good bike.
The clutch and throttle cable have both broken.
The kickstand plate could be stronger.
Finally, some bolts have come out (front brake caliper).
For me, it is better to save $4,000 to $5,000 and make these relatively inexpensive fixes. However, I do have a local mechanic repair the cables instead of ordering - apparently many others are having a similar problem, and maybe there aren't enough cables to go around.
If you got a used name brand, it would cost less to buy, have more power, and not much would go wrong with it, plus parts are easier to find.
The engine is too hard to break down, and there is no space to move anything. It took 3 hours to get it apart. The frame space is barely big enough to fit that motor on it, the bike is definitely a bike you can work on, and I'm never working on another one again.
I have always had a problem with getting high rpms out of this bike, but after I put a high flow air filter on it (lot's of modification, but I was able to put a 3" car air filter on) then I moved the c-clip on the throttle needle in the carborator down 1 spot (more fuel) I can easily go up to 9,000 rpm, before I could barely hit 8,000. Someone should try adjusting the needle before putting on a high flow air filter, and see how it goes.
2007 Baja X 250.
I have had this bike for about a year or so, and I have had absolutely no engine problems, but the bike itself might as well be useless metal. I don't know why anybody would ever think of making this thing. Again, I have had no problems with the motor; in fact I put it in a small quad and it's awesome, and was I clocked doing like 75!!!
I just bought a 2007 project X250 for 300. It cost me 150 in parts. $450 for a running dirt bike is good enough for me. I've looked at Hondas and Yamahas. I don't have the 2000 for something like that. Yeah, I know it's a Chinese piece of s**t, but the parts are cheap also. Mastertechsports.com has all the Baja parts you need at a decent price.
All I have to say is real bike mechanics could figure out a way to prevent these flaws from occurring twice. My suggestion is all of you stay away from bikes, period. I've had an X250, not lost a single bolt, no snapped cables, doing a decent 50mph, and you could've figured out that a little bit of sheet steel, a ruler, and a welder would've fixed your 'small tank' problems. I expanded mine to 2.5 gallons, using just the base curves to fit it to the frame. Next time you replace bolts, use bolts that don't come loose under vibration. Don't buy 'replacement' cables from the company that built a weak one, anyways. Have a real bike mechanic fab you a more durable set up.
