you need to lift the rear of the bike, by the grab handle, or hooks inside the storage area, or (carefully) a floor jack. the swingarm has to be 'floating' so you can move it up and down by hand to pull the bolts out of the lowering links. not too tricky, just get the rear of the bike off the ground and take it easy. Break the bolts loose before you lift the bike.
If you are at all mechanically inclined, it should not be hard.
