Not trying to start a brand war. Just tired of people saying "this" & "this" about such brand with out first hand experience... Which it seems you have witnessed the bad & the good personally. Its all good!
I do know the 700 came out well before there time & they do have a couple of issues. (the rattle noise is actually the manifold resting on a motormount!?!? Overtime it will wear a hole in the manifold.) If you upgrade the tires you have clearence issues... IMHO they tried to squeeze that big a$$ motor in to small of a space. For the most part from personal experience the 400 & 500 are farley sound machines. Can't weight to try out the new 800, and see if its all it can be.
Now if Honda would have put a real tranny in the new four-trax I would have one in my garage right now!!
As for the falling apart issues, I've seen many of guys who bought "four wheelers" when they should be owning a Quad. Big difference there. The Four Wheelers are built to play in the mud & be a general workhorse, not constantly pound the trails at high speeds. & this goes for all brands.
