They havn't discontinued all 2 strokes, but the new emmission standards for '07 are basically doing it for them. You wont see many 2stroke carburated bikes that can pass the test.

But, all hope is not lost. Many companies are testing and in some cases already in production of 2 stroke EFI machines that are much more efficiant and capable of passing the standard.
KingsJ: I would have to agree with 250kid. A 65 is a cool little bike but she will out grow it to quickly to justify buying it new. Save some money and look for something used. when she out grows it then maybe a new 80 or 125 would make sense.
