Shown is the new Kawasaki FD751V - DFI engine, which produces 25.0 hp (18.9 kW) at 3600 rpm according to SAE J1995 testing procedures.

Kawasaki Motors Corp., U.S.A. Engine and Power Products Division plans to begin rating its engines in accordance with SAE J2723 starting in September. Kawasaki believes this “critical power” rating will alleviate end-user confusion over horsepower labeling and “usable” power. Its production engines for lawn care and other maintenance equipment will produce at least 98% of their rated values, not the 15% potential variable permitted under SAE J1940, which has been the generally applied industry standard. The SAE J2723 rating methodology, in combination with SAE J1995 Gross Power testing procedures witnessed by global testing agency TÜV Rheinland Group, provides an accurate assessment for real-world equipment applications for the engines. Kawasaki plans to stress performance and integrity in ratings through reliance on the stricter SAE J2723 standard. The company notes that none of the newly rated engines will exhibit performance differences compared to current engines being sold.
