Need to put bike on jack stand. Put the jack stand under your rearset. Remove the top and lowers shock bolts. Shock will only come out the top. So you will need to loosen top rear subframe bolts and remove the lower bolts.
Tilt the rear subframe up from the rear. So you can get the shock out.

The Ohlins comes with instructions, basically what Yangins said. Undo the lower subframe bolts and pivot the subframe up to get enough clearance to remove the shock. The bottom bolt is difficult to get to but not impossible.
