lower gear to shift down to, and no «flat spot» in which the engine does not produce any power), the effective band changes in each gear, becoming the range limited at the upper end by either the limiter, or a point roughly located between peak power and the redline where power drops off, and at the
lower end the engine's
idling speed.
