Keihin was a Japanese manufacturer of fuel systems and engine components, founded in 1956 as an affiliate of Honda and headquartered in Tokyo. It supplied carburetors, fuel injection systems, throttle bodies, and air-management components as factory equipment on millions of Honda motorcycles and cars, making it one of the most common OEM brands found inside Honda engines. In 2021 Keihin merged with Hitachi Automotive Systems, Showa, and Nissin to form Hitachi Astemo, so the Keihin name now lives on within that larger supplier group. In Pakistan, Keihin carburetors and fuel-system parts are everywhere in the Honda ecosystem — CD 70, CG 125, Pridor, and Civic parts channels are full of Keihin-stamped OEM components. Mechanics recognize Keihin markings as the sign of genuine Honda factory parts, and Keihin carburetors remain the reference standard for Honda bike fueling. Its fuel-injection and air-management technology later served Honda's automotive line as well, including throttle bodies on popular Civic and City engines.
