## Power/weight ratio  The power to weight ratio calculates the the weight of engines/vehicles in kg per kW of engine performance. Here it is decided, how many kgs each kW has to move. For other vehicles unattainable, the Formula-1 engine rules with a top power/weight ratio of almost 0,15 kg/kW engine- (see picture) and approx. 0,9 kg/kW vehicle-power/weight ratio. Below, the data for standard motorcycles (net weight with a full tank) can be seen:

 2007 Yamaha YZF-R1 1,59 kg/kW (1,17 kg/PS) 2008 Suzuki GSX-R 1000 1,56 kg/kW (1,15 kg/PS) 2008 Honda Fireblade 1,52 kg/kW (1,12 kg/PS) 2008 Kawasaski Ninja ZX-10R 1,51 kg/kW (1,11 kg/PS)

## mFPe = mPF
