revolutions is the only replacement for displacement. Honda engines are usually oversquare, (shorter stroke, larger bore) then other engines of the same capacity, Allowing them to change direction more quickly. Hence they can rev higher.
Why does my engine rev so high?
The most common cause of this revving is either a stuck throttle or the mass airflow (MAF) sensor. This fault should be addressed as soon as possible for normal operation as this revving can become dangerous if the vehicle is allowed to accelerate unintentionally.
Why can Motorcycles rev so high?

Is high rev good for engine?
Higher revs equals more power, which is particularly nice to have, especially in a sports car. A simple way to go about creating a high revving engine is making sure the bore is larger than the stroke. A wider bore also leads to improved airflow at high rpm – F1 and motorcycle engines make for the best examples.
