Other "stuff":
camping chair: do not go out and buy a tiny camping stool thinking you're clever in saving money and space. You need a camping chair with a back, not so,e dumb stool that you have to sit on top of instead of sitting into a comfy chair. We are on bikes all day long, riding some rough terrain and stressing our bodies plus we are carrying weight on our bikes more so than on simple day rides so every time you need to maneuver your bike over and around ibstacles and every time you have to pick up your bike, your back is going to take the brunt of it no matter how fit you are. A simple three legged camping stool will cost about $20 and and ultralight weight camping chair will set you back a fevers chilly $130 but I found a happy middle ground - while so many people were spending $130 on these amazing Alite camping chairs, I discovered like so many other products nowadays that they're made in China and found a source for the Chinese manufacturer who was happy to sell them unbranded for a cool $45 shipped. Over the past two years these "knock-offs" have become more popular so now even some camping retailers are selling them for about $55. I will provide some links for these chairs further down but do yourself a favour and spend the $55 on a perfect camping chair - do not count on finding a comfy spot when wild camping or leaning back against a tree or other tough-guy approaches. This camping chair folds up to a tiny package and weighs about one pound.
Knives, axes, machetes, etc: again, this is a personal choice...if you're camping at a provincial campground, you have to buy fire wood from their store to avoid the spread of invasive species of bugs that can ruin our parks. If you're wild camping, you'll need to cut and chop wood and that is not going to happen with a fancy titanium folding pocket knife. A machete is great for cutting sticks but not perfect for chopping thicker wood. There are pocket saws that are very good for cutting wood but I haven't tried any so I have no opinion on them. An axe is good but I carry a tomahawk - it can chop like an axe, hammer in stakes, cut like a saw, break tire beads from your rims for trail side flat fixes and take down offending and threatening animals like a hot knife through butter. Let's be honest, if a bear shows up, I'll crap in my pants just like anyone else but I'd rather use bear spray on it or if I don't have any, I'd rather swing a tomahawk at it than face it at close distance with a knife. I can't say I've had any personal experience fighting animals so far but I'd like to think that I've thought it through and am somewhat prepared for such things.
Lighting: I carry a camping headlamp - Petzl is probably the best product on the market regardless of which one you get but be aware that there are essentially two types: replaceable disposable battery units and rechargeable units. I personally would rather jump into Mac's Milk and buy a pair of triple A batteries instead of worrying about how I'm going to charge my headlamp on a multi-day trip. Don't underestimate the need for a headlamp; its necessary. When I'm in my tent or hammock, I also hang it on the ceiling to create space lighting. Don't bother with a traditional flashlight / torch type of light, they're simply too bulky for the most part and using a headlamp frees up both hands.
Food: to be honest, when I'm motorcycle camping, I don't pack any food apart from snacks (granola bars, etc.) - I typically find a restaurant to go eat at otherwise any convenience store or gas station will offer canned food that's easy to buy when required. Yes, the idea of cooking a steak and enjoying it with a chill drink while camping over an open fire does sound appealing but really??? I'm limited by space and weight so I prefer to hit up "local" food when possible. On the other hand, I'm totally addicted to my Turkish coffee (as are my fellow riders now) so I do pack and being my ground Turkish coffee, sugar and tea with me. I have two cooking / boiling solutions that I will choose from for camping on my bikes: I've got a JetBoil stove with a built in pot and it uses canned camping fuel. It will boil a litre of water in three minutes and one can of the fuel will last seven days easily. The other is an MSR Whisperlite Micro stove which uses the same fuel and is a tiny and simple stove element that you can out any pot on top of. Either way, I do not use these stoves that require white fuel or can burn the fuel from your bike - I can pop into any gas station convenience store and buy more canned fuel for $3.00. I've done a few trips with four guys in total and the one JetBoil is all that is needed for four guys, no need for every person to carry cooking gear. The one thing I will say though is that you should have your own mug of some sort and your own spork plus your own snacks and Advil, etc.
Water - I use a water bladder backpack (also Kriega but there are hundreds of others like Camelback, Klim, etc.). Mine holds three litres of water and uses a drinking tube that so I can drink while riding. Apart from that, I also bring an MSR Dromedary bag (those are available between 4 -10 litre capacities) and I will keep it empty and rolled up until the last stop for fuel, etc before heading to camp overnight at which time, I will fill it and it straps right onto my bike or luggage bags. Yes, you want fresh drinking water at the campsite - coffee, hand washing, etc - yes, carry your own water.
Extra fuel - many people obsess over fuel capacity and I'm not trying to make light of the topic, running out of fuel sucks balls but people who spend a fortune adding capacity to their own bikes tend to forget two things:
1- extra fuel means extra weight on your bike and often not in places that are ideal for extra weight (like up high on a bike)
2- if your fuel range is 400km but the other guys have a range of 200km then guess what: you're stopping for fuel every 200km anyhow regardless of your own capacity
on the flip side, I love riding with guys who have a ton of fuel capacity as when they fall asleep, I can just siphon fuel from their bike into mine
On a serious note though, extra fuel is good to have - many people have been successfully using the same MSR Dromedary bags (meant for water) to carry fuel. This definitely works but while they remain leakproof, the Dromedary bags do allow the fuel fumes to escape so they get pretty stinky of fuel. There are other options such as other bags that carry fuel without smelling through and there are hard-can options from small MSR cooking fuel cans to large Kolpin containers - you choose what's right for you but if you want more details on options, let me know here...
towing straps, tie-down straps, etc: different straps for different purposes...
towing - it is not easy to tow a fellow rider on a broken down bike. There are many choices for simple tow straps that don't need to be super strong as you're not pulling a 1/2 Chevy pickup out of the trail, just a bike and one unlucky guy on it.
Tie-down straps - I love Rok-Straps; they're compact, very strong and are the only straps I know of that combine both nylon webbing plus elastic sections. I haven't found anything else that can safely and securely tie just about anything down onto any part of a bike or its luggage. I know a few people who use IKEA pinch straps and they seem to work, I just don't trust them and they don't offer the elasticity of the Rok-Straps
First-Aid - I carry a very simple first-aid kit with me on these trips, everything from bandages, tape, pain killers and elastic bandages plus small instant-ice packs just in case.
