About Keihin
Japanese-built carburetors, EFI components, and engine fuel-system hardware
Keihin is one of the two most important names in motorcycle carburetion (alongside Mikuni) and a major OEM supplier of carburetors and electronic fuel injection components to Japanese motorcycle manufacturers. The brand's FCR-series flat-slide carburetors are popular four-stroke performance upgrades, and Keihin OEM-replacement carburetor and EFI parts are direct fits on most Japanese motorcycles.
Chaparral Motorsports has been an authorized motorcycle and powersports dealer since 1980. We stock Keihin alongside the full range of motorcycle, ATV, and UTV gear, and our parts counter can confirm fitment and compatibility before you order.
