Auto Racing: power weight ratio, coefficent of friction, power to weight ratio

Question
Hi,
some motorcycles have higher power to weight ratio than others despite having less net power. For example bike 1 weighing 147 kg and producing 14.5 PS of power has a power-weight ratio of 98 PS per ton. Bike 2 weighing 122 kg producing a power of 13.5 PS has a power-weight ratio of 110 PS per tonne. But still the bike 1 manages to beat the bike 2 in 0- 60 kmph and 0-100 kmph timings. Why is it so? Shouldn't the bike 2 be faster than bike 1?

Answer
You are confusing power to weight with speed. I can take a very heavy car and gear it to run faster than a lighter car. Its all in the way the power is aplied to the ground that matters when speed is concerned. Aerodynamics also factor in as well as coefficent of friction.
