Wyodude, there are probably a million little tips that you pick up after you have been riding for years. We all take them for granted after awhile and forget to mention them to newer riders(like my wife). Only a couple of things come to mind right off the bat.
When no special motorcycle parking areas are available and you are forced to park with the cars, don't pull up all the way in the parking spot. If there is a car on each side of you, your bike can't be seen and some people see a open space and whip in there and hit your bike before they realize that it's there.
When parking in places other than on concrete, carry something to put under your sidestand to keep it from sinking into the ground. Even an asphalt parking spot can cause the sidestand to sink far enough to down your bike in the hot summer.
Carry an extra key on a separate key chain,when leaving town or going a great distance. I'll never forget the time that I whipped my key out of my pocket only to have it fall into the sewer grating.
There are many things that we all do that we do from experience that we don't even thing about. One thing that is a good habit to get into is just giving your bike a quick looking over before you ride. Look at things such as the brake pads, tire tread, tire pressure, oil level, lights working(especially headlight and brake light), belt condition,loose bolts, unclosed saddle bags etc. If you do this regularly you can skip a few things now and then but still reduce the SUPRISE factor down the road.
