Yes they are , I was however trying to compare apples with apples.
The ANs are two strokes against the NRs being a 4 stroke.
Its a lot easier to get a given amount of HP out of a 2 cycle engine than 
it is out of a equal weight 4 cycle engine ,simply due to the double
number of power strokes per revolution.
Of course this is somewhat offset by the poorer fuel consumption.
