I keep 2 of these in my toolbox.

You can also just use a big screwdriver and a hammer too.

Adjusting with shock unloaded makes it easier too.

Ohlins Shock Spanner Wrench

Somewhat more universal rather than fixed. But if piken uses two of the same, that's more using two of them to break loose and tighten the rings. A punch and hammer flattens the square cuts and drags on the other ring where that punched metal is squashed out and no free spinning ring occurs as if using the correct tool.

I don't know what the size for the "hook wrench" as they are also known as for shock, but the one I used was similar to what piken posted and a second wrench would have made the job easier but it was doable with a single wrench.

When you go to make adjustments definitely unload the rear shock! I have a tire rack in my garage which supports up to 800 lbs so I strapped the rear of the bike to the rack using ratcheting tie downs to lift the back of the bike. Once the tire was just off the ground I was able to make the adjustment, tighten the locking nut then lower the bike.

Don't forget to take measurements for the static sag of your bike before you start and with the extra weight you are planning on carrying (ie, gear, luggage, passengers, etc) and figure out how much sag you want when you are finished. Lower the bike and re-measure with the extra weight after you have made some changes to figure out how much more you need to adjust. I think it took me about an hour to rig everything up, adjust and remeasure a few times.

I used the one made by Kaw. If the Ohlins one works, I'd go with that. Heck of a lot cheaper and the Kaw tool is no work of art.

If they are a different size for all of the different bikes boy what a racket that is! Like cell phone chargers ..

IDK but aren't they all (about) the same size??

I have one of these. Hasn't met a shock it doesn't like yet. For the '14 I take off the left rear set and access that way.
