it takes a certain amount of HP to maintain a given speed(dependent on
gearing,drag,powertrain losses,road grade,wind directions...),and that HP
might be not be achieved at 2000 rpm. it would increase cylinder
wall/piston wear.

the SI has only 2 liters displacement,and it's HP and torque is developed
on the high end of the RPM scale.
