Critical Power

Critical Power

Precise, powerful, SAE Certified.

Kawasaki Critical Power engines adhere to SAE J2723, an automotive-caliber standard that’s among the tightest in the industry. It demands that engines deliver at least 98% of rated horsepower. This strict rating method eliminates variances that may produce less precise horsepower numbers. When you choose a Critical Power engine, you get true SAE Certified power.

How horsepower becomes Critical Power.

SAE Certified Power - Critical power

First, horsepower test equipment, procedures, measurements and calculations are set according to strict SAE J1995 protocol.

Second, precise power tests are run. Procedures and results are confirmed by TÜV Rheinland Group, an independent testing authority.

Third, horsepower ratings are set per SAE J2723, the same automotive-tight standard used for your truck engine. As one of the toughest rating standards in the industry, it ensures accurate, consistent power output.

It’s a rigid, multi-step process that ensures you get all the power you expect from the engines you count on. Only Kawasaki Critical Power engines give you that assurance.

Horsepower FAQs

Q: Why did Kawasaki go to Critical Power?

A: Our Critical Power engines use a tighter horsepower testing and rating method than much of the industry, providing a more precise horsepower number. This better reflects Kawasaki’s advanced engineering and manufacturing technologies, provides a more exact horsepower rating, and ensures you get all the power you expect.

Q: Have the engines changed in any way?

A: No – Critical Power engines are identical to previous models: same model number, same power output, same shape, size and design. Only the horsepower rating is different.

Q: Why is the horsepower number different from what it was?

A: Different rating methods give different results for the same engine. Our new testing and rating methods result in a new, more precise horsepower number. The power output itself is unchanged.

Q: Isn’t a bigger horsepower number better?

A: It’s not the number that matters – it’s the actual power output. Some rating standards provide bigger, less precise numbers, and the engine may not be capable of delivering all the power that’s advertised.

Q: Why is Kawasaki power testing verified by somebody else?

A: Third-party verification helps ensure precision and consistency in horsepower testing methods and claims. Kawasaki uses a world-recognized, German-based authority, TÜV Rheinland Group, to verify horsepower testing, and results are certified by SAE International, so there is no doubt they are accurate.

Find Your Critical Power engine.

Your preferred engine has the same model number, design, and power as always. It may have a new horsepower number based on a tighter SAE J2723 rating, but the output has not changed.

Only Kawasaki Critical Power engines identified on this website have been tested in accordance with SAE J1995, verified by TUV Rheinland Group, horsepower-rated in accordance with SAE J2723, and certified by SAE International. 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.
