At $600, that is quite a bargain compared to the $1200 difference CF Moto charges for an EPS model. My closest CF Moto dealer just sold the z800 non-EPS model he had, the same one I test drove back in April, and I passed on it knowing full well I wanted the EPS model. Priced down to $9k, I could have added the SuperATV kit to it and come in at least 500 less than the EPS model.
I also know that unit is a solid one, as my FiL has been running it for over a year in his Pioneer 500.
