XR400 Spark plug.

What is the wrench size (head and length) needed to get a spark plug out from the plug recess on a Honda XR400?

To know the size I need the plug, but to get the plug I need the wrench!!

Saves me buying a plug just for the sake of the size!

Extended High Speed Riding: DPR9Z (NGK) or X27GPR (DENSO)

It's 18mm.

If you haven't got the Honda tool, Motion Pro do one.
