BIRMINGHAM,
Ala. (May 2, 2009) - In an
ongoing effort to maintain a competitive
balance among all manufacturers competing in
the AMA Pro Daytona SportBike presented by
AMSOIL division, AMA Pro Road Racing officials
dyno tested the 10 motorcycles that qualified
for Friday's Superpole session at Barber
Motorsports Park.
"AMA Pro Racing is dedicated to ensuring
that we deliver to our fans great competition
on the track between a variety of
brands," said AMA Pro Racing President
Roger Edmondson. "This was an important
step in getting the formula where it needs to
be to make good on that commitment."
It was the first test of its kind performed by
AMA Pro Road Racing officials on Daytona
SportBikes, although similar tests have been
performed in the past for Canadian Superbike
and SunTrust Moto-GT bikes. The dyno tests
revealed that the bike with the highest
weight-to-power ratio was 2.65 pounds per
horsepower, and there was a difference of 0.49
pounds per horsepower between the top
performer and the lowest-ranked bike among
those tested at 3.14 pounds per horsepower.
There was a 0.28 pounds per horsepower gap
between the first- and second-ranked bikes.
AMA Pro Road Racing officials will now utilize
this data along with other variables, such as
aerodynamics, ram air, rider size and lap
times to determine if any additional
performance modifications are necessary to
provide a better show for AMA Pro Road Racing
fans.
"This is the first time we've ever done
this at AMA Pro Road Racing," said
Director of Competition Colin Fraser. "We
will analyze these variables along with a
multitude of other things that affect
performance on the track. The most important
variable to analyze is lap time. After all, we
race at the track, not the dyno."
A complete listing of the dyno testing results
will not be released, as raw horsepower is
meaningless without an inclusion of all the
other variables. Any adjustments to the bikes
will be announced once all data is analyzed.
