Long before the Motorcycle Safety Foundation developed the T-CLOCS checklist, even before MSF existed, we were taught to wipe our bikes down because in so doing we would find loose or missing nuts and bolts; fluid and air leaks; rust spots that were developing; and any other problems that might leave us stranded. Back then we could be anywhere out in the woods, and there were no cell phones! It was also a good time to check lights, oil, tire pressures and fill up with gasoline.
All too often, when a friend stops by and says "Let's ride!", the tendency is to just jump on the bike and go! Gas is usually the only thing we'll beg to make a stop for. I've seen friends lose tail light lenses, license plates, get pulled over for malfunctioning lights, and was even towed home through the trails at 2 am once myself, for not taking the time to do these checks!
Familiarize yourself with the checklist:
