A bit of a trick question. A stock crf250r would run in the 65-70mph range.
There is a difference between 2 stroke and 4 stroke, hopefully you know that part. yz250 is a 2 stroke, and yz250f is a 4 stroke. 2 stroke 125cc is the same as a 250cc 4 stroke. a 250cc 2 stroke is the same as a 450cc 4 stroke. so if you get the yz250, it will be ALOT faster then the yz250f, there different kinds of power. hopefully that helps.
A CRF250R is a 4 Stroke bike.. And the CRF250X is a 2 stroke. E.g one has a power band and the other does not
