Very interesting test, good info.
But I wonder about a couple of things:
1) How much difference does it make that they tested with an R6?
That is a very light bike compared to my '00 Sprint ST.
2) Using the GPS to measure corner speeds.
What kind of GPS was it?
My experience with GPS has at least +/- 15 feet, so even a 100 ft corner would have significate errors.
Thanks for the info,
David W. Funk
