I ride alone often and someone else mentioned in another thread here that good body armor was essential when riding solo (or any time if you ask me). But then I got to thinking about what one would consider essential items to carry along on a solo off road ride. I think this topic may have been covered before, but I just thought I'd see what others consider absolutly essential. A lot of these things I have learned from my solo hiking days. Here is a list of my essentials for solo riding. Digital camera - not an emergency item, but I almost always carry one Cell phone + spare battery (fully charged) GPS (sometimes two) MAPS!! - I'm surprised at how many guys I see out in the woods without a map. FRS/GMRS radio (thinking of getting a portable Ham radio too. For the extra range) Compass Whistle Spare NiMH AA batteries - I have a little carrying case I bought off of eBay; it holds 8 but I usually cary 12 Emergency space blanket Mirror for signaling (don't laugh, might save your life) First aid kit Ibuprofin/Asprin Several Power bars Two liters of water (minimum) Waterproof matches and fire starter Small poncho Small roll of twine Toilet Paper; no reason to be crude even when lost in the woods Then there are the tools; Leatherman (carry this if you carry nothing else) Spare inner tube (one 21in tube will work for either front or back) Some way to inflate a flat tire (small hand pump, Co2 etc.) Assorted wrenches and such, but most importantly axle nut wrenches. Spare spark plug cable-ties some sort of tape; duct or electricians These are just the basics that I carry; It may seem like a lot of stuff but I usually carry most of it between my front fender pouch, the over the number plate glove box and my back pack (which also holds the water bladder) - and I just put on a rear rack on the DRZ and have a small tail bag on order for even more tote space. I have other odds and ends and I am constantly changing my load and what I carry but I would consider these things essential; at least when riding solo; I usually leave a few things behind if riding with a buddy or a group. Anyone else care to share what's in their backpack?
