Secondly, the main feature of the 465 Shock is the RAP, which stands for Remote Adjustable Preload. This is the black knob on the end of the steel-braided line that is mounted in an easily accessible location. The benefit of this system is that you can, with the turn of a knob, adjust your preload. The proper way to use this shock is to set the sag for you and what is normally on your bike. Then, when you ride two-up, you can quickly add a turn or two. Then, when you ride two-up with a bunch of gear you can add even more preload. But then, when you get to a campsite or motel, you can ditch your passenger and luggage, take out all that preload and go for a more serious off-road ride without dealing with the traditional sag adjustment.
