6mm hex drive sockets

[sheep shagger]

I have a few motorcycle tool kits that use 6mm allen as the drive for all sockets. Although it's stupid for garage toolkit, it's actually a great idea for a bike toolkit, since everything is small & light, plus the drive doubles as a 6mm allen wrench. Anyway, I'd like to expand the kit to include a few other sockets, but my google-foo is ****, I can't seem to find anything.
Here is a pic of a similar kit, hopeful you can see what I mean.

Toolkit is re-branded by KTM and I believe it's originally made by Unior Tools, but there is no mention or 6mm drive on their site. http://www.uniortools.com/categories/sockets-and-accessories

Any ideas? I'd really like to add to this kit rather that chuck it for a 1/4 ratchet, extensions + sockets & allen.

Just reviving this thread. Id love to find the same as the original posted. I have the same KTM kit, but would love to add to it. Any thoughts?

Might be easier to find or make a 6MM hex to 1/4" drive adapter..
