and i have no experience whatsoever so it has to be sturdy and i was thinking around a 125 4 stroke.
i don't care about speed as much as dependability and i don't want to work on it.
i will also be jumping stuff but no more than 15 feet.
and last but not least i need it to bee $1000 or less.

I really like KTM, but Yamaha is a good company.



if little to no experience, it would be best to start him off on a mild 4 stroke trail bike, like a Honda CRF80/100/150F (not R) or a Yamaha TTR90/110 or a Kawasaki KLX90/110 if those aren't too small for him. or if he is taller, CRF230 or TTR230 which are mid sized height wise but tend to be on the heavier side. these are all air cooled, older designed and bullet proof engines with moderate (at best) brakes & suspension but great bikes to learn how to ride on.
if he has some experience and is more agressive, something like a CR, KX, RM, YZ 80/85/100 or CRF 150R small wheel or expert (depending on his height) which will have all the performance upgrades including suspension & brakes.
if he is 5'6" or taller, he might be able to fit a full size bike…
again, little to no experience, XR, KLX, WR, CRFX 250
or if some experience and/or agressive, CRF, YZF, RMZ, KXF 250…
I would advise to start off used to save yourself some money as he might quickly outgrow or loose interest… then once he finds what really fits him, then you can always upgrade to newer…
also what to look out for when buying one

If it were me, I'd get a late-model four-stroke. The power delivery is smoother and they're easier to ride. Check out the Honda CRF250 (or at least the CRF230). Yamaha, Kawasaki, Suzuki, and KTM all make excellent bikes. Some people only buy certain brands (mine are Honda and KTM), but they are all such advanced machines that any of them will be more than enough bike for you. Get at least a 230cc, but only if you're willing to need to buy a bigger bike in a year.
For the record, I ride a 2003 CRF450. If I had bought a smaller bike, it simply would not have been powerful enough, and I'd have had to buy a bigger bike. But I've been riding for over 20 years, and so I knew I needed a big bike.

You may also want to look at this link regarding emissions testing. I did a quick look at it & it doesn't look like they test bikes, but you may want to contact your local IL DMV testing center to make sure.

Good luck anyway
