I can recall being very glad that I had a deepwell 8mm socket with the extensive tool kit that I carry on the dirt bike; it made removing the cover over the front sprocket far easier. I'm still not sure how I got a rock up on top of the sprocket, but, that's trail riding.
However, for my street bike, I do use the kit that Honda provided in the fall of 1988, when they shipped my bike to the USA, as my emergency roadside kit.
