Top Daytona SportBikes dyno tested

From AMA Pro Racing

BIRMINGHAM, AL - In an ongoing effort to maintain a competitive balance among all manufacturers competing in the AMA Pro Daytona SportBike 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.
