How horsepower becomes Critical Power

Only horsepower that is tested per SAE J1995, rated to
SAE J2723, verified by TÜV Rheinland Group and certified by SAE International qualifies as Kawasaki Critical Power.

Testing procedures and accuracy are observed and confirmed by a registered TÜV Rheinland Group witness, who verifies that equipment function and calibrations, computations, and engine test settings are correct and consistent.

Every TÜV Rheinland Group witness is a test engineer who’s met criteria established by SAE International. Witnesses confirm that all test procedures and measurements are accurate, that all testing equipment is spot-on, that every calculation is correct, and that every SAE J1995 rule is followed to the letter. And, they independently double-check test results to make sure they’re what they should be. When a TÜV Rheinland Group witness says an outcome is accurate, it is accurate.

Once test procedures are verified, test results are certified by SAE International, the independent worldwide engine specifications authority.

After testing verification and outcome certification, Kawasaki rates engine horsepower per SAE J2723 guidelines, one of the strictest standards in the industry. These guidelines require that most production engines produce at least 98% of their rated values, much tighter than the more commonly used 85% required by SAE J1940.

LEGAL DISCLAIMER
Only Kawasaki engines listed on this website have been tested in accordance with SAE J1995, verified by TÜV Rheinland Group, and certified by SAE International. The gross power ratings of these engines were determined by using measurements according to SAE J1995 which were witnessed by SAE-approved witnesses from TÜV Rheinland Group. Torque ratings of these engines were not certified by SAE. Actual power and torque output will vary depending on numerous factors, including, but not limited to, the operating speed of the engine in application, environmental conditions, maintenance, and other variables.
