To start, a KLR handle bar bag was added providing a great spot for glasses and gloves and anything else you find yourself constantly putting on and taking off. Great design, though not quite waterproof.
SW Motech waterproof and shock-protected iPhone case and mount that I borrowed from my mountain bike. The case is a clam shell that seals with an o-ring with waterproof ports for power and headphones. The screen retains its touch sensitivity, even with my gloved hand. The device rotates 90 degrees and has a stout quick release feature. In my haste of sorting out my interface with the KLR, I ordered a RAM mount system for the iPhone without even considering what I had on hand. Few iPhone users understand that the device has a dedicated GPS chip that works independently from cell service, so it can be just as effective as a standalone GPS and tracker.
Charging the device and powering other 12V accessories is this RioRand 12V/5V socket and power port between the clamps underneath the handlebar bag.
The last addition for this post is a Pelican 1520 top case. This was on the Montero and the H3 and held a breakaway cooking and mess kit.
