Do the YFZ450 have the same engine to the 450 motocross bike.

No............

The closest it was to the YZ, was in '04, when the WR and the YFZ were the same except for the crank and piston.

The YZ has evolved significantly, while the YFZ has had subtle changes along the way.
The motor mounts are way different but some parts are interchangeable though.
