The OEM shock spring fitted to the shock is only 70N/mm spring rate, so for most riders over 65-70kgs(143-154lbs), with no allowance for extra luggage or passenger, it will not give the correct sag settings required for adventure riding, which is 10% static(no rider) & 30% with rider, (20mm & 60mm respectively) based on the OEM shock stroke of 200mm.

Linear-wound springs, allowing for rider, passenger & luggage to travel in comfort. Also included is a pair of tough, plastic adaptor rings, to allow the fitment of the thicker coil heavier shock springs to the OEM shock which has a hydraulic preload adjuster. The 10mm stroke of the HPA (hydraulic preload adjuster) can allow for approximately 60kg (132lbs) of additional load, either extra rider, passenger or luggage weight, while still adhering to the 60mm rider sag settings recommended.
