Hayabusa (隼) is Japanese for "peregrine falcon", a bird that often serves as a metaphor for speed due to its vertical hunting dive, or stoop, speed of 290 to 325 km/h (180 to 202 mph), the fastest of any bird. In particular, the choice of name was made because the peregrine falcon preys on blackbirds, which reflected the intent of the original Hayabusa to unseat the Honda CBR1100XX Super Blackbird as the world's fastest production motorcycle. Eventually, the Hayabusa managed to surpass the Super Blackbird by at least a full 16 km/h (10 mph).

The Word “Hayabusa” is Japanese for “Peregrine Falcon”. Just like its namesake, Hayabusa is renowned for cutting through the air with extraordinary agility and performance.

Hayabusa is a Japanese word that translates to "peregrine falcon" in English. However, this term is widely recognized as the name of a spacecraft or a series of spacecraft developed by the Japan Aerospace Exploration Agency (JAXA).
