You won't be wringing the motor out for all it's worth in the wind at 75 mph. On the smaller 800, expect to run out of throttle now and then on the interstates..[/QUOTE]
You won't be particularly close to running out of throttle at 100mph on the 800, and heavy headwinds with large (madstad) screen and full panniers at 75mph won't stress the engine at all - if you were wringing it out you'd be well into the triple digits regardless of wind. At least that's my experience with the XC.
It's no measure of health to be well adjusted to a profoundly sick society
