This trak-tools kit has a couple of the open end wrenches (10mm, 12mm) that fit a 1/4" bit drive.
I wonder how these kits compare in size and function to the Motion-Pro MP kit?: http://www.motionpro.com/motorcycle/partno/08-0161/
I own one of the MP kits, have heard good and bad about it (and am not engaged to it). Every kit has some compromises it seems.
