Virtually all Japanese bikes (and I think most German bikes?) are set
conservatively. At one time in the past, I understood the reason for
this being a combination of:
1: Mechanics (and electronics?) vary, unless they cost more than the
2: The US has penalties on the too-aggressive side of estimation but
not the conservative side.
3: Tires wear - new tires show more-conservative speeds than
almost-shot tires, and I'm sure if people are changing tire sizes here
and there, it also fits into the variation part.
All five bikes in my driveway vary from about 5 to 8% optimistically, as
determined by a GPS unit in straight & (low-)level flight.
