Impossible to use on Honda ST1100
What a waste of money! Just pops out of the notch, even if you can somehow get it into the notch with a wrench or breaker bar attached (hits the shock or mount). You need to have a wrench which wraps around the shock at least 150 degrees to hold the tang into the notch. Otherwise it just pops out and rounds the notch long before the shock adjustment rotates enough to adjust it. This cannot be made to work with a heavy mono-shock rear suspension. A flawed design. Should have a much longer circular design.

Very useful in tight space
This tool is very easy to use in a tight/limited space. The 3/8" socket is quite loose fitting and not made with greatest quality, but it did its job. Very small and easy to keep in your tool box.

PROS: Lightweight easy to use

CONS: Socket drive too loose

Very low quality
Expect to use this one time. It is not a tool if you are always going to use it. It will not last.I bought it on the fly, but I should of paid to get a better quality one.
Flaws are that when you insert your 3/8 drive, it starts to tear the corners from turning the spanner to a stiffer setting on the shock, making a future wobbler socket which is worthless and dangerous.
