The 9.2hp Subaru KX21 Sports Karting engine is purposely built for performance. Fuji Heavy Industries Ltd (FHI), the maker of SUBARU cars, launched the Subaru KX21 Sports Kart engine, for racing and fun karts. It is based on the EX series of air-cooled, 4-cycle, OHC, petrol engines. .
The KX21 is designed to deliver the high power and performance required in karting. The KX combustion chamber is modified to raise the compression ratio to 10:1. Additionally, the air intake system has been improved over standard and the ignition timing changed to increase horsepower output without compromising fuel economy or increasing exhaust emissions. When mounted on a kart, this lightweight (15kg) engine provides agile handling and competitive driving performance and is able to run from the lowest idle speed to the highest RPM of 5600rpm smoothly and easily.
The KX21 is approved by The Australian Karting Association (AKA).
SUBARU engines have earned a reputation for their quality, reliability and performance. The introduction of the KX21 for karting signifies the companyÆs step towards meeting demands for performance engines across all industries.
This engine has gained acceptance at a number of industry recognised karting organisations and rental kart tracks all who have embraced the quality Subaru engines.
The KX21 has been developed as a kart-specific engine, featuring high RPM and power output at levels that general-purpose engines cannot match.
