I have had the mighty Zforce 800 Ex out a few times but not really broken in. Got my first(early) oil change at 200 miles last week. My son and I took it to Heart of Dixie ATV Park in Troy, AL and let it rip. I have to say each and every time I take this thing out it impresses me all the more. When I had my RZR at this park previously there would be bumps, washes, and drop off's that would jar you and feel quit sharp. The suspension on this Ex soaks up these obstacles VERY well. I didn't feel one sharp bump translated inside the cab all day. Long straight-aways we would hit 45 mph and the contours and terrain changes would be very "1972 Cadillac'ish". Americans will get that reference. All in all I know I'm preaching to the choir here but so far my "open minded" approach to this purchase has paid off big time. When people ask me about taking the risk on a little known product I always tell them I'm taking day by day and unless is cracks into two pieces next week I'm very glad I bought it! Happy trails kids! I hope this helps anyone on the fence about the possible purchase! Oh BTW my Scap Doors will arrive this afternoon. I will report on those ASAP.
