Put a jack on the lowest point of the oil pan. You can't do the normal trick of putting a jack on top of the tire and onto the subframe on the R6 because of clearance issues. Be careful when you do this and if you can find a way to stabilize it side by side because it will tip if you don't. What I did to remove my shock (pretty much the same procedure), is leave the swingarm stand on and lift it just enough with a hydraulic jack to take the weight off the swingarm but it was still stabilized because of the stand.
