Wow, a perfect balance of inertia, gyroscopic force, and knowledge of the bike, brakes, and tires...
We all have personal minimums. When I fly a plane I have a set. Typically in IMC (Instrument Meteorology Conditions) I fly down to +500 feet and 1/4 mile above the airport minimums. If I know the airport well and there are no changes to the approch procedures, then I might fly closer to the published minimums depending on the whole weather system. And if there is ics, then I don't fly! I don't fly if there is a chance of ice in the entire route!
And when it come to motorcycles, I don't ride if there is rain, or a chance of rain. Just my personal minimums...
