True, some BMW R1200GS toolkits contains a 19mm wrench you can use, in conjunction with the shaft of the screwdriver, to remove the oil filler cap on top of the left cylinder. But that means you have to dig out the toolkit (which is probably under the rider's seat, which you can't remove without first removing the passenger seat and whatever might be on top of that.
[Why did BMW do it that way? Wouldn't it have been better to make the rider's seat the first to come off, like the Yamaha FJR1300 and lots of other bikes?]
Anyway, I wanted a small and simple tool I could keep in the side pocket of my tailbag where it is quickly accessable. Here's what I came up with:
I started with a small red faucet handle which I bought at the local hardware store. It was about $3, if I remember correctly. I also got a low-profile 19mm nut.
I glued the two together and let they dry overnight. Here's the result. Not terribly pretty (though it looks better in realspace), but very useful. I particularly like the small size, and the fact that it feels very "natural" to remove or re-tighten the oil filler cap with this little handle. And being bright red, it is easy to find in my tailbag.
