This is a simple clip of a police motorcycle starting and revving up a few times. It doesn't have much of a roar but is much softer of an engine sound.
With resemblance to the sound of an engine, this sound can be used with various different mechanical objects in mind. This sound was bounced into 24bit, 48hz, interleaved audio. This sound was synthesised using a digital synthesiser.
