The Formula Z 670 uses a completely different rear suspension than the MXZ. The suspension was liscenced from AD Boivien and is basically their eXpert suspension. The Formula Z 670 also does not have the unequal length radius rods that the MXZ has. If you like nice slow rides down the trail to enjoy the scenery buy the Formula Z, otherwise get the MX.
