How Much Power Does the 2024 Kawasaki KX450 Make?

The KX450 enters a new generation for 2024, and in its redesign comes a revamped fuel-injected liquid-cooled DOHC four-stroke 449cc single-cylinder engine. Kawasaki developed a different layout for the intake system, and shifted the valves vertically to be symmetrical with the intake and exhaust ports for straighter airflow and improved efficiency.

A small airbox and restricted muffler make the 2024 model’s power feel lethargic in comparison to the prior generation’s on track, but the good news is current bike does make more than it above 9,000 rpm. In terms of peak figures, the 2024 Kawasaki KX450 spins 53.5 hp and 32.4 lb.-ft. of torque at the rear wheel according to our in-house dyno, which is 1.6 hp more and 0.2 lb.-ft. of torque less than last year’s model.

“The 2024 Kawasaki KX450′s overall engine character is easy to ride, and more deliberate in delivery than the 20192023 design,” test rider Casey Casper said. “It’s the best engine in class for vets and 450cc newbies.”
