Calculating Motorcycle Stopping Distance

While looking over my dashboard on wordpress, I found several search requests  for how to calculate motorcycle stopping distances.

Since one of my rules for this blog is not to get technical, I’ll avoid explaining the formula. Just enter the input values and view results. This is an excel spreadsheet download. You can download OPEN OFFICE free online and it will open the excel spreadsheet.

Keep in mind this calculator does not factor in perception reaction time! 

To add reaction distance:

Step 1. Convert MPH to FPS (1.466 is the conversion value)

IE 40 mph x 1.466 = 58.64 FPS

Step 2. Multiply 58.64 FPS with the desired time value (1.6 seconds is the average perception/reaction time)

58.64 x 1.6 = 93.82 Feet

Step 3. Add 93.82 Feet to the result (shortest possible non skid stop). Using a .7 coefficient of friction (dry well traveled road) the result was 76.19 feet.

76.19 + 93.82 = 170 feet (This is your TOTAL STOPPING DISTANCE)

Results are also displayed in metric.

Hope this helps.
