I posted this on a Gixxer Board and was curious. I'm trying to figure out concrete examples of how heat (ambient, not engine) affects acceleration. What, is it as much as .3 seconds in a quarter? More? Less? Do our bikes just FEEL that much slower in hot humid air? What is the formula the experts use to "correct" acceleration times to 59 degrees F and blah blah blah.... how much faster are our bikes at 48 degrees F instead of the 59 I see them use?????
Because I ride all year round in Boston I can tell you that little 650R is real pocket rocket in the winter.... in a straight line of course and never right off the line, so it's of limited use but still... OMG the difference.....
Anyway, here is part of the thread:
The problem is that you're then adding in more variables like traction, human control, etc Finding the relationship between temp and acceleration amoungst all the other variables will be difficult. You would need numerous runs and still may lose the data in the noise.

True, true it would take several runs with the same rider on different days on the same exact stretch of road and there are several variables including traction.
Is there a point at which it being hotter gives more traction initially but then becomes a hindrance throughout the run?
All of which fascinates me to wonder how the experts in the field use their formulas and data to "correct" test results...
