Big-D,
I am as minimalist as they come, but the FJR can hold more than enough. One thing I could not do without is the SW-Motech luggage rack. The stock one is useless and an aftermarket rack will give you something solid to secure your ties to in the rear. Oh, and it looks good, too.
I got in the habit of sending unused items back home on my first few lengthy trips, and that helped refine my packing list to what it is now. I travel light for a variety of reason, but mainly I saw it as a challenge to not be encumbered by stuff I do not need.
Here is a pic of my usual configuration:
Blue waterproof bag on seat: Tent (Taj 3), footprint, sleeping bag. NOTE: I used a bungie net to secure the bag and it was much better than the traditional straps. Hooked two on the rack, and two under the front hooks of the pannier. Worked great.
Left pannier: Clothes, liners, flip flops, toiletries, book.
Right pannier: Thermarest pad, bike cover, stove, pan, foldable bowls, plates, cups, small LED lantern, air compressor, large knife, microfiber towels.
Tank bag: Radar Detector, MP3 player, clear helmet faceshield, recharge cords, camera, Leatherman Wave, Petzl Zipka (best all around light made!).
Under the seats: Large tool set, first aid kit.
Still room in the bags for a few food items, although I usually hit the store before hitting the campsite for the night.
Not telling you what to pack...just wanted to illustrate much the FJR can carry with only 1 small additional bag. No, the bags were not bulging...they closed easily with room to spare. I camped primitive for 6 weeks with this setup. I am looking at a smaller tent and more packable sleeping bag...and I should be able to use just the panniers. Have fun on your trip!
Regards,
Davy
