So Far, So Good for 2007 919
Well, I managed to get a multi-tool (your screw/bolt type here) with the chambers where you push up the bit required through the nozzle into one of the recesses, under the seat, and a couple of other handy multi's into the other slot under the seat, both held down with factory bungees. I have a top case, but with laptop shoulder bag, 2 six packs of very important craft beer and two stainless drink containers (one for water, and one for coffee from the morning), there was little room for anything else. Obviously, on a longer ride I might sacrifice the beer room for salvation tools, but for the 15 mile commute, I think I'll survive.
I've seen ads for the Leatherman Wave, but there's a lot of blades in there that just don't make sense from a mechanical perspective. Is there a Leatherman with a full suite of metric Allen ends?
