I too have a 2007 or maybe 2008 Big Bear, can't remember exactly. I bought it specifically to work. It is the 5th ATV I've owned. I wanted one inexpensive, compared to others anyway, no frills, no electronic junk etc. It replaced a 2006 Yamaha Rhino.
Two complaints so far- until it warms up good and goes a few hundred feet it is very hard to shift. Apparently this is a common Big Bear "feature".
The wife says it hurts her toes to shift. Once good and warm it is ok. I run the "synthetic" Shell Rotella T 5w-40 in it and that helped the shifting.
The oil filter is a PITA, it is a cleanable screen deal, messy and really only catches big junk. I'd prefer a spin on or cartridge paper filter. Of course the cleanable one saves money, if it does well enough to avoid early engine wear out. Since the filter isn't so great I do frequent oil changes...there went the savings..oops.
Bottom line- would I buy it again? Absolutely, for the money as a work machine it can't be beat. It isn't flashy, it isn't a trail racer, but with the really, really low first gear it will do some serious work for a very reasonable price.
