If you travel long distances on a motorcycle, you will have lots of wild weather. I ride in the rain a little more cautiously, looking for surface hazards and carrying too much speed on the side of the tire. Not much beyond that. If the temps are below 40, I am careful riding over lane paint too. It can cause a little slip here and there, but nothing dramatic. Modern tires are very grippy in the wet. Even DOT knobbies.
For me the big thing is comfort and good visibility. Dry and warm rain gear and a helmet that allows me to deal with the fog. If the rain is hard enough to hurt visibility, I pull over for a half hour or so. The squall passes and all is well again.
With the right gear I can ride rain for days on end and enjoy it the same way as if it was dry.
