I decided to add some preload to the rear mainly because I will soon be riding with some luggage and I’m afraid the bike will go “tenere” on me. My old Tenere 660 had a suspension issue when loaded with luggage and gear. The issue was that the suspension compressed so much that the bike would nearly tip over when put on the side stand. Granted, I had lowering links installed (with a shortened side stand), but it was very annoying still.
The following is a description of what I did to my bike. It’s not intended as instructions to go fiddle with yours. Don’t touch your bike if you are not knowledgeable of what your are doing.
The rear suspension adjustment is relatively easy and quick to do.
1. The right middle side panel needs to be removed
2. The rear brake reservoir needs to be unscrewed and taped out of way
3. The bike needs to be lifted so that the is no load on the rear suspension
4. then it’s a matter of hammering away at the locking/adjustment rings
4A first tap open the upper locking ring. Some WD40 on the threads will not hurt. Consider also drawing a mark on the ring and shock to be able to tell if you are getting the parts moving.
4B tap the lower ring to where you want it. Be carefull not to go too far and run out of thread. On my bike the spring wanted to rotate with the ring, but I see no harm in that.
4C tap the locking ring tightly against the lower ring
5. Reassemble the bits you took off and you are done.
The end result is a bit surprising. I though that the adjustment would not have a much of and effect, but the bike sags much less now. The downside is that the seat height went from perfect to too high with no luggage. The bike feels now exactly the same as my old 690 Enduro. A bit too high. The first pic shows how much thread is visible above the rings after the adjustment.
