You'll find at this price that the components will be the bits you'll have issues with. Cheaper 3 piece cranks tend to be amongst the first parts to go. You'll often find the splines (the small grooves that hold the crank arm in place on the bottom bracket axle) will strip meaning you'll have to replace them pretty quickly. And no, before anyone pipes up - it won't be covered by warranty if you've been using the bike for jumping / park riding. Even though the bike is designed for this, it'll be excluded from the warranty cover.
Another thing you may need to think about changing pretty quickly would be the wheels. Off the peg wheels tend to be pretty poorly built. Look for something with steel rims (heavier but stronger and better braking), 48 spoke and with a serviceable hub. No point going for cartridge bearings when the wheels are going to take a kicking. And they will. especially if you're learning to jump!
Take a look at the Specialized Fuse Two & Three. Both have good frames and a good level of equipment. The Fuse Three at $400 has a full Chromo frame and slightly lighter wheels. Otherwise have a look for the GT Bump at around $300. All good places to start.
Whatever you get, don't expect it to be unbreakable. Even the really expensive ones get busted, especially if you're just getting started. Remember to save some money for pads & a helmet. And have fun!


http://www.frpoffroad.com/ is probably the best site for KDX products, Jeff Fredette has be racing KDX's for 20+ yrs and should have the parts you would ever want for it.
PS: Never WD40 or Armorall the brakes or seat… you won't like the results

Of course, some guys got busy hopping them up with stuff like aluminum frames, tall seats, etc. –– but retaining the over-achieving motors (usually punched out to 110cc), the 10″/12″ rear wheels, and the tossable proportions that make a pit bike such frickin’ fun. Because a track for these bikes doesn’t require a lot of land, backyard pit bike tracks have sprung up all across America.
Pit bikes now have a full race series with numerous classes (even one for young ladies), five AMA National #1 plates up for grabs, and an exciting ArenaCross Pro & Amateur Series.
and then of course the dirt bike is well just your average dirt bike :]

Dirt bikes are safer for several reasons. Dirt bikes are more like riding regular bikes, which is something that most kids know how to do. The turning of a bike and dirt bike is done less with handlebars and more with a leaning motion. This helps to change the center of gravity, and place the weight of the rider away from the bike when a fall starts. Dirt bikes tend to not fall on the rider during a fall, and if they do, it tends to be less of the bike. In the case of quads and trikes, the rider is almost always confined within an imaginary box located very close to the bike. Falls on quads and trikes tend to be rollover type injuries. Secondly, when it comes to the weights of the two concerned, a similiar size (displacement of engine, or cc) bike will be smaller than a trike or quad. Think about, the parts to control and hold together two wheels would be less than that of three or four wheels. Thirdly, I'll use my own emergency room experience as a doctor. I see far more injuries to children coming from trikes and quads than I ever see from bikes.
Thanks,
