Suzuki's first move on acquiring the rights to the ON360 was rebodying it and replacing the Mitsubishi engine with an air-cooled 359 cc (21.9 cu in) Suzuki "FB" two-cylinder two-stroke which produced 25 PS (18 kW; 25 bhp). Since the new unit remained smaller than 360 cc, and Suzuki placed the spare tire inside the truck (making it a three-seater) to keep it under 3 m in overall length, it was classified as a kei car, conferring certain tax privileges and other benefits.
