The 95' 700 Cat was a great trail sled, in 1995.
Before purchasing this sled check to see
if it has a balancer for the crank shaft on it. ( The true ZR's came with them)
This will eleminate the typical 700 vibration.
In addition the 700's did have a terrible stock clutch and jetting setup.
My personal opinion (from vast experience with these sleds is

Unless you plan on spending a great deal of time "Dialing in" this sled I would
choose to look at a different modle. (I.E. any of the tripples, zr580's, ext's)
If you really want this machine on the other hand you will have to do some
heavy duty clutching, jetting and suspension work to keep up with any of the newer
sleds and some of the sleds of that era.
It was a good sled in its day, but since then we have all come to reallize that for
the same amount of money there is much better equipement with more potential.
