Immediately following each qualifying session or race, the top finishers plus other motorcycles chosen at random will be tested on the Official Series Dynojet dynamometer to verify rear wheel horsepower. The test numbers will be generated on the dynamometer using only numeric readings, with the “smoothing” set on five, using an “SAE” horsepower calculation. Compliance with the minimum weight will be determined by weighing the machine in the exact condition in which the machine finishes any competition activity (qualifying or race final) without the addition of fluids or other items of any kind.
