I'm looking at buying an 07 rmk 700. It has 2200 miles, looks clean. The first owner did lots of stuff to it. Skis, can, front shocks, vents, etc. I cant figure out where he got the rear suspension set up or if its even from a polaris haha. I know the sled has been pretty modded up for a racer, but an older man has owned for the last 3 years and he has barely rode it. looks like it had nos too. Here are some pictures... can you guys tell if anything else is done to it?
