A 249cc inline 4-cylinder engine that emits a sensual sound

The greatest appeal of the Ninja ZX-25R SE is its 249cc in-line four-cylinder engine. This power unit produces a maximum output of 48ps at 15,500rpm, and produces a sensual exhaust sound at high revs. The smooth rotation feel and sharp acceleration characteristic of a four-cylinder engine are enough to captivate any rider.

Combined with the aggressive Ninja styling, this model combines high performance on the circuit with comfort for city driving. The thrill you feel as the engine revs up will bring you excitement you wouldn’t expect from a bike of this displacement.

Enhanced performance with a comprehensive electronic control system

It features a trellis frame that maximizes performance, and is equipped with numerous rider support systems, including KTRC (Kawasaki Traction Control) and KQS (Kawasaki Quick Shifter) with auto-blipper. High-performance electronic controls allow riders of all skill levels to safely and efficiently maximize the machine’s performance.

The instrument panel uses a 4.3-inch full-digital TFT color LCD display, an advanced feature worthy of the Ninja ZX series name.
