A YZ250 is much faster than a CRF250r. The YZ250 is a 2 stroke where as the CRF250r is a four stroke.
Yamaha YZ250 hands down. Both bikes are designed for a different purpose. The YZ250 is a 2 stroke motocross bike. The WR250F is a four stroke enduro bike.
Well if you look at it in the science way then it is obiously 2012 yz250 but the way that other people look at it then it is 2012 yz450f
They have 5. Owner of a 2007 crf250r

A bit of a trick question. A stock crf250r would run in the 65-70mph range.
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
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.
