Kawasaki’s did it, just like I said. It turned up the heat in the two-wheeled world with the official announcement of the 2025 Kawasaki Ninja 1100SX. You’d think stuffing a bigger engine in there might balloon the price, but no, Kawasaki’s kept it steady at $13,699, just like the outgoing Ninja 1000SX. Now, if you’re looking for something a little more dressed up, there’s an SE version with Öhlins suspension and Brembo brakes, all for a neat $15,399.
The 2025 Kawasaki Ninja 1100SX Brings the Goods
At first glance, the Ninja 1100SX sportbike looks like its predecessor—same sleek body lines, aggressive stance—but the real magic happens under the skin. The stroke’s been increased by 3 mm, bumping the engine to 1,099cc from the previous 1,043cc. A set of 38 mm throttle bodies and a new intake port get things flowing, pushing up torque to 83.2 lb-ft. at 7,600 rpm, a slight gain over the 1000SX. Though horsepower dips slightly to 134 hp at 9,000 rpm (down from 140 hp), Kawasaki’s strategy here is clear—optimize that low-to-mid-range grunt where most riders live, rather than chasing peak power.
On the transmission front, fifth and sixth gears are now longer, making for a smoother power delivery in fifth, while sixth gear’s stretched out for more relaxed cruising. And yes, the bidirectional quick shifter now works at a lower 1,500 rpm, offering even more shifting flexibility.
The chassis? Familiar but refined. The standard Ninja 1100SX gets a larger 260 mm rear brake disc for a bit more stopping power. If you spring for the SE model, though, you’re treated to Brembo front calipers, fresh brake rotors, and an Öhlins S46 shock at the back. Kawasaki even threw in weighted handlebars to keep those vibrations in check and added a USB-C outlet for good measure.
As for tech, the 1100SX carries over the same electronics package as before: three ride modes, cornering traction control, ABS, and cruise control. The 4.3-inch TFT display manages it all, with smartphone connectivity via Kawasaki’s Rideology app.
Expect these bikes to roll into U.S. dealerships by Winter 2025, with the standard version sporting Metallic Carbon Gray and the SE dressed in Emerald Blazed Green.
