In the "general safety" category so that you and your bike survive to ride:
Always have fire extenguishers in the garage/workshop/etc. LOTS of them. Mounted properly on the wall, checked for charge occasionally and free of clutter and hanging debris. If you work on motorcycles or cars or anything long enough you are liable to set something on fire and having a fire extenguisher handy can be a garage/house/life saver.
While riding:
Never initiate a turn into an intersection too soon. This is a frequently taught item in most driving schools and is referred to as "early apexing" on the track but never seems applied to street lessons. It applies to motorcycles quite frequently on the street, though. As you roll into an intersection that you plan on turning the natural inclination is to start drifting toward the direction of the turn and then cutting the corner short so to speak. This can cause REAL problems if the corner is sharper than you thought or if there is not as much room in the lane to turn into past the intersection (parked car, narrow lane, etc.) or a car suddenly pokes its snout into the intersection causing you to straighten momentarily to miss it. Now you are faced with clearing the obstacle and THEN making a seriously sharp turn to stay on the road. I have personally witnessed several bike accidents caused by this:
Stay in your lane until well into the intersection, to the point that you can see down the lane you are turning into.
Claim your space in the lane you are in, don't anticipate space to finish the turn in the lane you are going into.
Square off the turn in the middle of the intersection by countersteering forceably so that you are entering the lane aimed in the direction you want to go.
If you are making a right hand turn, no one says you have to drift to the right side of the lane to "setup" for the turn. Stay to the left, use the space to clear the corner and then initiate the turn.
Doing this correctly requires you to slow down at the initial part of the turn, get the bike pointed and then accelerate thru the turn as you are straightened out....much like the road race courses teach you in driving school.
This same sort of situation gets many people into trouble entering a main road from a side street stop sign. They pull past the stop sign, get on the throttle and then start turning to stay in the lane. That is why you often see them run wide and into the opposing lane. Roll thru, make the turn and then accelerate. Seems simple but watch people ride and you will see it done wrong quite frequently.
Countersteering practice:
Find a vacant back road and practice running down the middle of the road and weave the dashed lines on the highway USING ONLY THE INPUT TO THE HANDLEBARS. Start slow and speed up. You will be amazed at how fast you can whip thru the lines with countersteering practice as you learn to force the bike back and forth with the bars. You'll be amazed at how hard you can yank the bars to miss an obstical without falling. Obviously....expert rider/closed course, use at your own descretion, has been known to cause serious injury, etc.....
