Kawasaki has announced an enhanced Ninja 1100SX for 2025.
Despite the increase in engine size, the Ninja 1100SX will retain the same U.S. price as the 1000SX at $13,699. Kawasaki also revealed an SE version that will set you back $15,399. The Ninja 1100SX will be available in a Metallic Carbon Gray/Metallic Diablo Black color scheme, while the SE version will get Emerald Blazed Green/Metallic Diablo Black. Both models are expected to arrive in U.S. dealerships by winter 2025.
The Ninja 1100SX gains some cubes, going from 1043cc to 1099cc for 2025 to enhance low- and mid-range performance. Kawasaki increased the stroke by 3 mm, maintaining the bore at 77 mm. The engine now features new 38 mm throttle bodies and a revised intake port.
Slightly sharper looks and more cubes give the Ninja 1100SX a new lease of life.
A heavier flywheel has been added while a secondary balancer helps reduce vibrations.
The intake port has been narrowed to increase airflow, while the camshaft profiles now produce less valve lift, leading to better fuel efficiency and low-to-mid-range performance (a similar trick was pulled when Kawasaki released the latest version of the ZX-6R last year).
Torque has increased slightly, with a peak of 83.2 lb-ft at 7,600 rpm, compared to the previous 81.9 lb-ft at 8,000 rpm. Kawasaki USA has not released official horsepower figures.
The gearbox has been updated with longer fifth and sixth gears for more fuel-efficient freeway cruising and the gearbox’s quickshifter now works at 1500 rpm, 1000 rpm lower than in 2023.
The chassis is pretty much as you were. The suspension on the standard model includes a fully adjustable 41 mm inverted KYB fork and a horizontal back-link shock. The SE model, however, will Brembo M4.32 front brake calipers that were first seen in 2013 (there’s been about six model updates since then, sigh), a new master cylinder, and an Öhlins S46 rear shock with, happily, a remote preload adjuster.
The electronics package remains the same, featuring three riding modes, an a six-axis IMU metering Cornering Traction Control and Cornering ABS. The dash is also the same in the 4.3-inch full-color TFT display and you’ve also got access to Kawasaki’s ubiquitous Rideology app.
