Believe It Or Not
I'm at an advantage because I have a Sargent saddle and a hard, QD rear trunk case mounted to a modified Ventura rack (but using the Ventura L-brackets). Consequently, I carry all sorts of stuff (see below) that I never hopefully will need, which if I did not drag along would of course immediately would require for a roadside fix (Boy Scout / SEAL Team 1 philosophy). I have used my tire plug kit and Co2 filler on a friend’s RC51 but otherwise never have touched it (knock on plastic - NOP). The added weight of all the stuff I carry in addition to the OEM tool kit possibly exceeds 10 pounds! Of course I also always carry my cell phone, Cobra RD & have a Garmin Nuvi 765T w/BT & MP3 player (feeds stereo BT ear buds with navigation & tunes; don’t bother with connecting to cell).
In the Sargent saddle tool tube and a zipper leatherette bag in the trunk plus stashed in the trunk and under the saddle: OEM Tool Kit, Vice-grips, Super Leatherman, duct tape, Super Silicone (adhesiveless) tape, lighter-meltable hot glue, electrical tape and wire, zip-ties, a small tow rope, on long trips mc jumper cables, a travel battery charger and one or two 1.23 qt. camping stove "spare" gas bottle, 2 small LED flashlights (1 of which you can hold in your mouth while working) and when camping also carry a LED/Halogen headlamp, extra headlight, stop/tail & turn signal bulbs, an emergency "space" blanket, Areostitch's sport touring First Aid kit, more bandages and antibacterial ointment, alcohol wipes, a razor blade/holder, spare ear plugs, a side stand plate with remind-me-to-take-it lanyard and handlebar hook, tire plug kit, Co2 filler with at least 10 cartridges, screwdrivers, special wrenches, ratchet & sockets, a mini-adjustable wrench (very handy) and 7" adjustable wrench, clear 3/8" ID hose (for gas siphoning), tweezers and scissors, tire gauge, Motrin, lighter, pen, pencil and note pad, Magicmarker, a mini-RS electric multi-tester, spare fuses, sunscreen and bug repellent, a small microfiber towel, a faces shield cleaning kit plus a small bottle of Rain-X, water bottle, a clear face shield in a thin helmet bag (I wear a dark tint during the day), sunglasses, maps, rain/cold weather gloves back-of-the-hand squeegee, a windproof wind triangle, spare , head sweat, a windproof and rain resistant PB bicycle illumiNITE jacket, crimp connectors & splices, adjustable bungie cords, a disk lock, lightsticks, elastic hair ties & rubber bands, caution tape, a baseball hat, Totes rubber over boots, an 3/16" diameter X 24" vinyl covered lock cable and a separate helmet cable with built-in lock, on long trips an electric tire pump I made from the guts of a C-H unit plus a dual-cigarette plug outlet (that also can be used with my cell phone car charger) that plugs into the coaxial receptor that I plug my Battery Tender into, mini-bungies, more zip-ties, the remote for my alarm, a disk lock with caution tape taped to it (a bright reminder to remove b4 flight), spare keys, extra batteries, gum and lozenges, cigars, hand & foot warmer packets, eye drops, spare eye glasses & sun glasses, my insurance card & DOT excerpt on how headlight modulators are legal in all 50 states (I have needed it at least once), plumber's epoxy, spare gloves sometimes for hot or colder weather, and other stuff I'd have to check to see I forgot about. Everything is organized in zip-lock freezer bags (plus spare bags) and I have a small LED light velcro'd to my full face helmets for map reading, and on my helmets my blood type, "no med allergies" and "do not remove helmet" stickers I made. I have a Scott Oiler, so chain lube is not required (except I also bring a refill bottle & pint of engine oil plus "2nd side stand" in made that lifts the rear tire for long trips), Camel Back, tank bag, etc.
In 60,000 miles on my VTR I've never had to do a road-side repair of my bike... (KOP)
