Ha ignore previous reply, too quick on the buttons
What I was going to say was the c-spanner in the tool kit needs to be used with the bar extender also supplied in the tool kit. The shock settings can then be adjusted using this tool without much effort so long as the rear is off the the ground with bike on a proper stand. If the bike is on the side stand then to use the tool you have to have add a longer extender or have a more substantial c-spanner. Also more effort is required and so risk scratching bike if the spanner slips.
