T-CLOCS as taught by the MSF course is a good checklist to base your pre-ride inspection. I use it to remember what I need to check at minimum. But there may be other things that you might want to check in addition to the basic list.
Pre-ride inspections are important because you don't want your machine going down while you're on it. One guy at my MSF class went down on the freeway because his pegs came off. As for me, when I put my mirrors and frame sliders back on, I didn't put them back on tight enough. I rode 20 miles without being able to see what's behind and beside me, and then I found out that my toolkit doesn't have the right size hex tool to tighten my slider back on. So now I check them just in case.
Doing regular pre-ride inspections will help you notice differences. For example, as you inspect your chain, you might notice that there is more slack than usual. If you parked in a parking lot, you might see something out of the ordinary that a stranger/vandal did.
I park my bike in the garage at home. On occasion I will just do an inspection even if I'm not going out. I figure I might as well do it in case I miss something right before I ride (e.g., I'm lazy or late). But you should still do a quick pre-ride check before you take off: you never know if something happened between last night and the next morning. Once you get used to what you're looking for, you can do an inspection in 2 minutes. I actually start the engine and let it warm up while I'm inspecting the bike. If I'm idling my bike for a couple of minutes, I might as well look it over.
I don't have anything else to add to T-CLOCS other than to add things that you might deem important to look at, like your rearsets so that your pegs don't fall off...lol Once in a while I will check bolts...I once lost a windscreen bolt and the one that took up the slack was just about to go as well. If you need us to cover T-CLOCS in particular, just let us know.
