The motorcycle community is buzzing with excitement as Kawasaki prepares to unveil its highly anticipated 2025 Ninja 1100SX, set to replace the existing 1000SX model. Featuring a larger 1,099cc engine, this new iteration promises to deliver thrilling performance and cutting-edge technology. While official details are expected during an announcement on October 1, we’ve gathered some key specifications that offer a glimpse into what riders can anticipate.
Performance Insights
Initial reports based on homologation filings from Australia revealed the model name and codes—ZX1100H and ZX11002J—without extensive details. However, further insights from Switzerland have clarified what to expect from the Ninja 1100SX. The new model boasts a peak output of 100 kW (134 hp) at 9,000 rpm, a slight drop from the 140 hp produced by the Ninja 1000SX at 10,000 rpm. Despite this reduction, the Ninja 1100SX compensates with an increase in torque, reaching 83.3 lb-ft at 7,600 rpm, compared to 81.9 lb-ft at 8,000 rpm for its predecessor.

Dimensions and Design
In terms of size, the Ninja 1100SX maintains the same dimensions as the 1000SX, with no alterations in height, length, wheelbase, or weight. However, it does feature modified sprocket ratios. The previous model had a 15-tooth front sprocket paired with a 41-tooth rear sprocket, resulting in a ratio of 2.73. The new model, certified with a 42-tooth rear sprocket, has a revised ratio of 2.80, which contributes to its enhanced performance characteristics.
Speed and Transmission
Interestingly, even with a decrease in peak power and a similar weight, the Ninja 1100SX is projected to achieve a top speed of 251 kph (156 mph), surpassing the Ninja 1000SX’s top speed of 249 kph (154.7 mph). This increase suggests that Kawasaki may have optimized the transmission ratios, allowing for better acceleration and a higher maximum speed.

Remaining Mysteries
While the specifications we have are promising, there are still several unknowns regarding the Ninja 1100SX. Details about its electronics, suspension, and braking systems remain under wraps. As the announcement date approaches, enthusiasts are eager to learn more about the innovations Kawasaki has implemented to enhance the riding experience.
In summary, the 2025 Kawasaki Ninja 1100SX is shaping up to be an exciting addition to the sport-touring segment, blending historical performance with modern advancements. Keep an eye out for the official announcement on October 1, where Kawasaki is expected to unveil more details about this exhilarating motorcycle.
