Pretty hard fool
Suzuki makes a good bike, however this is too vague of a question. This would depend on what model of Suzuki dirt bike, the type of riding you do, maintenance and how hard you ride it.
You can not drive a dirt bike (as in motocross bike) on any street. They are not meant for roads. They have no lights or indicators and the noise and pollution levels are also very high usually. You can't register a motocross bike. It would be very impractical and expensive, as the costs of maintaining a motocross bike are staggering. For example the engine can only last 20-50 hours of working time before you need to rebuild it. If by dirt bike you mean hard-enduro type bikes, then it's a different story. They are usually legal to drive on roads, although not very practical or comfortable as well.
The difference is that the mountain bike tube is much burlier and wider than the dirt jump tube but may not be as strong in terms of hard hitting strength.
They have a VIN on the frame but can be hard to find and are not all in the same spot.
all a racer does is just like any other would train hard and get to move up to more competitive races
Any bike can be jumped but the landing is the hard part. In your case I wouldn't try it unless you have a death wish!
I'd start with a dirt-cheap MTB. It's most likely to be made of a steel alloy that's not too hard to weld motor mounts and stuff to.
so dust and dirt dont get in it.
for 370 its hard to find a good dj bike. your best bet is to look for one used cuz unless you have a least 700 dollars your not gonna get quality bike.
14.. i have one and i can drive it perfectly well.. its not hard to drive.. id say you can drive one at 12-13 with a helmet
If the Hard drive is IDE (40 pins on the back) you would configure the primary hard drive as Master and secondary hard drive as Slave using the jumpers on the back of the hard drive.
if you are doing simple little jumps, the light bikes of today make it easier, but it still takes patience and practice. if you want to be an x fighter rider that would take a lot of skill and years of practice. http://www.dirtbikefanatic.com/dirt-jumping-bikes.html
