Police use In 2006 the Oklahoma Highway Patrol (OHP) converted a seized Hayabusa into a pursuit vehicle, setting up the bike with equipment including a radar unit, police lights, and siren, and painting it in official colors and insignia. Impressed with the positive response from the public and the motorcycling community, the OHP purchased two more Hayabusas, to supplement their main fleet of Harley-Davidson police motorcycles. While they are used for patrol, the primary function of the Hayabusas is public relations and community outreach, due to the kind of attention the exotic bikes attract. According to the OHP, "There are clear lines dividing sportbike and cruiser motorcycle riders. We feel the sportbike community has not been given the proper amount of attention and focus in the area of community involvement and rider safety education." In 2009, Humberside Police in the United Kingdom put an undercover Hayabusa on the road, equipped with speed detection equipment and a video camera, as part of Operation Achilles'', which aimed to catch speeding motorists and motorcyclists. In the town of Arecibo, Puerto Rico, the Puerto Rico Police operates a "superbike unit" composed entirely of seized Hayabusas that have been outfitted with lights, sirens, police livery and radar equipment for speed enforcement duty in the northern region of Puerto Rico. In late 2021, the Arecibo municipal government announced the acquisition of seized vehicles for the Arecibo Municipal Police in conjunction with the Puerto Rico Department of Justice, among them a Hayabusa. Like the Hayabusas owned by the PRPD, this Hayabusa has been outfitted with lights, sirens and police livery to be used as a patrol vehicle in Villas del Capitán Correa, located at the northern part of the town.
