Hello Rene and list,
Just to stick in my two cents, and to clarify a few statements you made...
> ...For the average rider ( not the top 1%) stopping distances will be

The qualifier here is that Braking Gods (those rare riders who are very
adept and practiced at threshold braking, the likes of a Nick Hayden), can
obtain shorter stopping distances under the following conditions:
o Known performance limits of motorcycle and track
o Good (or better than good) traction is available
o High state of readiness
Tests have shown that Joe Average on an ABS-equipped street bike can stop in
a shorter distance on a rain-slicked road than compared to a Brake God on
the same bike (but non-ABS) under identical conditions. This alays held
true, even after the Brake God was given multiple runs to try to shorten the
stopping distance. This demonstrates the removal of only one of the three
criteria I listed above. I stress that someone who is astoundingly good at
braking *cannot* outperform ABS in conditions where traction is
significantly compromised on the street. This includes the "Top 1

In the 2001 model year, BMW introduced semi-linked, servo-controlled (AKA
"Whizzy") brakes on the R1100S (my current bike). The hand lever applies
both front and rear brakes (proportioned correctly), while the foot pedal
applies only the rear brake. On the 2000 model year (my previous bike) and
earlier, the R1100's brakes were not linked (the hand lever controlled only
the front brake while the foot pedal applies only the rear brake).
