Went out looking for a spare tire mount that would work on my 900 without taking up what little bed space I have. There are a bunch of them out for aftermarket cages but very few for stock machines. Found one made my PRP (the seat people) that folks seem to be happy with. There are four different models of it; RZR 570/800/900/1000 and they all look pretty much the same - almost ordered the wrong one. Install was easy and solid. Only down side I can see (so far) is that it adds about 10 3/4" to the overall length of the machine.
