Pros and Cons in comparison

Kawasaki Ninja 1100SX 2025

The standard version of the Ninja 1100SX also benefits from the most important upgrades for 2025: the more practical engine, the revised traction control and the changed gear ratio make the Ninja fit for the future. Minor weaknesses such as the high fuel consumption and low payload diminish the overall impression somewhat. Yet the Ninja 1100SX SE remains an excellent sporting motorcycle for riders looking for comfort and dynamics in equal measure.
