Question about kawasaki KX 250 F Motorcycles
The most common causes for this are a ceased piston (for instance, if there was an oil failure, the bike probably wouldn't have ceased until it was turned off) or if an internal bolt has gotten into the bottom end somewhere jamming the crank or kick mechanism itself.
Try removing the cylinders first, as that is the most likely cause of the failure.
If the piston is stuck in the cylinder, you may need to put a block of wood onto the piston and gently tap it out of the cylinder to effect repairs on the bike.
If the pistons come out of the cylinders without sticking, then having the cylinders removed will let you get a look into the crank area for loose bolts etc.
Don't forget to tie off the cam chain so it doesn't fall into the crank, because that's a pain to fish back out.
If you can't see anything wrong in the crank area, you will likely have to open up the bottom end to see what has gone wrong.
I wish I could be more help, but you didn't specify which bike you have.
If it's a 2 stroke, chances are the gas/oil mix was off or it ran out of 2 stroke oil and the piston ceased.

Hi,,sounds like the motor has seized. put it in a high gear and see if you can push start,,if the back wheel dosnt turn,,then your motor has seized,,if it does and the bike starts,then something is going on with the kickstarter gear.
