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
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.
The 2005 YZ450F (third generation) had just over 52 HP
Every bike goes about 20km less than the cc's. So a 450 would go about 420km to 450km. Probably the honda. I dirt track a yz450f set up with 13/35 gearing on half mile track and get 70mph
about 90
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.

87 Yamaha YZ250

The Yamaha Motor Company produces the YZ450F. This is a type of motocross bike. It is widely credited to be the bike that started the four-stroke bike revolution.
Selling a 1997 yz250 really depends on the condition it is in and the person selling it. Most 1997 yz250 usually sell for around a thousand dollars and lower.
The 2012 mustang is faster. Even though the camaro has more hp the mustang is lighter and faster than the camaro and the charger / challenger.
