If you were thinking the Ninja 1000SX needed a power boost, you’re in luck. Meet the 2025 Kawasaki Ninja 1100SX ABS. Let’s review what Kawasaki did to make the 1000 into an 1100, along with a few other updates.
- Kawasaki added 3mm to the stroke of the 1043cc Ninja 1000SX. The result is the 1099cc 2025 Kawasaki Ninja 1100SX. By going with a longer stroke instead of a larger bore, the 1100SX features more torque, delivering 83 ft-lbs of the good stuff at 7600 rpm—an additional foot-pound 200 rpm sooner than its predecessor. Kawasaki also narrowed the intake port and retuned the ECU.
- The transmission is updated to match the additional power. With sport-touring in mind, 5th and 6th gears are higher on the 1100SX. Kawasaki engineers also gave the 1100 a higher primary reduction ratio and lower final gearing. While the overall gearing is longer, the sense of acceleration should not be diminished.
- The quickshifter on the 2025 Kawasaki Ninja 1100SX is refined. According to our contacts at Kawasaki, the quickshifter works more smoothly at lower engine speeds.
- The USB power outlet has been upgraded to USB-C. Time marches on in the world of electronics, and USB-A is being phased out.
- There is also an SE version of the 2025 Kawasaki Ninja 1100SX ABS. Hand over another $1700 to the dealer, and you get an Öhlins S46 shock and a Brembo braking system in the front.
- The Öhlins S46 shock features tool-free remote spring-preload adjustment. Owners who turn the Ninja 1100SX into a sport-tourer will appreciate this convenience as a rider and luggage—both optional—are added to the platform. Internally, the Öhlins S46 shock keeps the oil and gas chambers separate for improved action. Damping is also fully adjustable.
- Brembo takes care of the braking up front. The master cylinder, M.4.32 calipers, and 300mm discs are all from the high-performance braking coming.
- The rest of the Ninja sport-tourer-in-waiting remains unchanged. We liked the 1000, so we have no complaints about that. The IMU-enhanced electronic suite returns with cruise control, traction control, and pitch management. A 4.3-inch TFT dash that integrates Rideology The App Motorcycle (yes, that’s the name) allows wireless interaction with your smartphone.
- Kawasaki has plenty of accessories to turn the 2025 Ninja 1100SX into a sport tourer. You can add panniers, a top case, larger windshields, a tank bag, heated grips (standard on the SE), and protective bits and pieces.
- You will have access to the 2025 Kawasaki Ninja 1100SX (and SE) in the winter. The standard 1100SX has a list price of $13,699. As usual, Kawasaki has posh names for the colors. The standard model is Metallic Carbon Gray / Metallic Diablo Black, and the SE sports Emerald Blazed Green / Metallic Diablo Black.
