2025 Kawasaki Z900 Official Confirmed Specs and Electronic Throttle, IMU, KQS Delta Briefing
Official technical spec delta briefing for the 2025 Kawasaki Z900 ABS unveiled at EICMA. Upgraded with Electronic Throttle Valves, the 948cc inline-four generates 124 hp (91.2 kW) and 98.6 Nm of torque under Euro 5+ standards. The platform adds standard electronic cruise control, a bi-directional Kawasaki Quick Shifter (KQS) from 1,500 rpm, IMU-guided cornering management (KCMF), rigid radial-mount front brake calipers, and a 5-inch TFT cluster with turn-by-turn navigation.

Electronic Throttle Valves and Euro 5+ Compliant 948cc Inline-Four
The definitive mechanical upgrade of the 2025 Kawasaki Z900 is the adoption of 36mm Electronic Throttle Valves, fully transitioning the model into a Ride-by-Wire architecture. By supplanting traditional throttle cables with electronic servos, the high-speed engine ECU precisely calculates intake air volume and fuel delivery with microsecond responsiveness. Retaining its oversquare 73.4 mm bore and 56.0 mm stroke architecture with an 11.8:1 compression ratio, the 948cc inline-four satisfies stringent Euro 5+ emissions while preserving an exhilarating 124 hp (91.2 kW) at 9,500 rpm and 98.6 Nm of torque at 7,700 rpm. Acoustic intake funnel engineering continues to deliver the intoxicating Sugomi roar while optimizing mid-range throttle elasticity.
IMU-Driven KCMF Lean Aids and Radial-Mount Braking Architecture
The chassis electronic suite undergoes a generational leap through the addition of a compact Inertial Measurement Unit (IMU). Continuous real-time tracking of chassis pitch, roll, and yaw angles powers the Kawasaki Cornering Management Function (KCMF), stabilizing braking and line-holding performance throughout turn entry, apex transition, and corner exit. The system harmonizes 3-stage KTRC traction control, selectable Power Modes (Full / Low), and 4 integrated Riding Modes (Sport, Road, Rain, Rider Manual). In parallel, the braking hardware abandons legacy axial brackets for rigid radial-mount 4-piston calipers grabbing 300mm semi-floating rotors, providing crisp lever modulation and zero flex under intense track or mountain deceleration.
Touring Ergonomics with Standard Cruise Control, KQS, and 5-Inch TFT
Beneath its sharp streetfighter silhouette, the 2025 Z900 incorporates an arsenal of long-haul comfort amenities. Leveraging electronic throttle control, factory-standard Electronic Cruise Control mitigates right-hand fatigue during extended highway cruising. The dual-direction Kawasaki Quick Shifter (KQS) comes standard, enabling seamless clutchless upshifts and rev-matched downshifts from 1,500 rpm upwards. The cockpit is upgraded to a crisp 5-inch full-color TFT display featuring RIDEOLOGY THE APP smartphone synchronization, projecting turn-by-turn navigation cues directly onto the cluster and enabling voice-command functionality through compatible Bluetooth helmet intercoms.
