Corte de giro is a Portuguese phrase used in Brazilian motorcycle culture for revving an engine until its limiter cuts in, creating the stuttering exhaust note heard here. The sound became a staple of short-form bike videos, where riders film their motorcycles at meets, on the street and in stunt clips. Its popularity comes from that instantly recognisable rev-cut rhythm, which creators reuse as shorthand for power and presence even when the bike itself is only on screen for a few seconds.
