TECHNOLOGY
ASSIST & SLIPPER CLUCTH
When excessive Engine braking occurs, the Slipper cam comes into play as a result of rapid downshifts (or unintentional downshifts), forcing the clutch hub and plate to operate apart. This reduces pressure on the clutch plate to reduce back-torque and helps prevent rear tire slamming and skidding. This racing feature is very useful when sport riding or riding on the track.
ECONOMICAL RIDING INDOCATOR
When fuel consumption is low at a certain speed and fuel efficiency is high, the ‘ECO’ mark remains on, and fuel consumption can be reduced. Effective vehicle speed and engine speed may vary by type, but paying attention to the conditions that cause the ‘ECO’ mark to appear can help minimize negative impacts on the environment.
ELETRONIC THROTTLE VALVES
Kawasaki’s electronic throttle actuation system allows the ECU to control the volume of fuel (via the fuel injectors) and air (via the throttle valves) delivered to the engine. Ideal fuel injection and throttle valve position result in smooth, natural engine response and ideal engine output. This system also contributes significantly to reduced emissions.
KQS (KAWASAKI QUICK SHIFTER)
Designed to help riders maximize their acceleration on the track with clutchless upshifts, at full throttle, KQS detects that the shift lever has been moved and sends a signal to the ECU to cut the ignition so that the next gear can be engaged without using the clutch. During deceleration the system automatically controls engine speed so that the next downshift can be performed without operating the clutch.
KTRC (Kawasaki Traction Control)
KTRC, Kawasaki’s advanced traction control system that enhances sport riding performance and provides service when facing slippery surfaces with confidence. Various modes can be selected by the rider (The number of modes varies depending on the type of motorcycle) according to the rider’s choice and level of disturbance
Power Mode Comparison
Kawasaki types equipped with several Power Modes offer a choice of engine power delivery that can be easily selected to suit conditions or riding choices. In addition to full power mode, there is also a choice of one (Low) or two (Mid-low) where maximum power is limited and throttle response is lighter.
Smartphone Connectivity
Advanced technology that can connect riders with their motorcycles wirelessly. Using the ‘RIDEOLOGY THE APP’ application that can be downloaded via smartphone. Vehicle information can be viewed on the smartphone such as Odometer, Fuel Gauge, Maintenance Schedule, etc. Rider logs can also be viewed through this application.
Horizontal Back-Link Rear Suspension
Kawasaki’s Traditional Uni-Track rear suspension is mounted vertically unlike the Horizontal Back-link rear suspension which has a nearly horizontal shock unit. Kawasaki’s original suspension setup places the shock unit very close to the bike’s center of gravity resulting in mass centralization.
ABS (Anti-Lock Brake System)
Kawasaki ABS system has front and rear wheel sensors to constantly monitor wheel speed. If information from both sensors indicates wheel lock, the ABS ECU directs the pump in the ABS unit to regulate brake fluid pressure (releasing and reapplying pressure to regain traction), ABS Ensures greater riding pleasure.
DOMINANT ENGINE PERFORMANCE
The only In-Line Four in the 250cc class
Kawasaki’s new compact 249.8cc liquid-cooled DOHC In-Line Four engine is a first in the 250cc class. Built with feedback from other ZX models, the high-performance engine offers the most power in its class and a range that can reach more than 17,000 rpm.
DOMINANT ENGINE PERFORMANCE
FEEL GOOD POWER
Ninja ZX-25R with In-Line Four engine – the key to the joy felt when riding it – delivers performance that exceeds the capabilities of a 250cc motorcycle, as well as the highest power in its class, namely 35.2 kW {47 PS), making this motorcycle able to deliver very linear power, suitable for riding in the city (low rpm), and rpm can continue to increase beyond the pulling range in the 250cc twin class. Engine performance is very good in the range of 10,000 to more than 17,000 rpm, which is also suitable for sport riding on the track.
DOMINANT ENGINE PERFORMANCE
Smooth Engine Response
The Electronic Throttle Valve (ETV) not only provides a natural and smooth engine response, but also facilitates the use of Kawasaki electronic rider support systems such as Traction Control, selectable Power Modes, and a dual-direction Quick Shifter that allow riders to experience a variety of sensations with their machines.
DOMINANT ENGINE PERFORMANCE
More Air, More Power
The trademark feature of the Kawasaki ZX type motorcycle is the Ram Air channel system located in the middle, following the Ninja H2 design, increasing the efficiency of air intake, thereby increasing engine performance.
DOMINANT ENGINE PERFORMANCE
Teknologi kopling yang terinspirasi dari motor balap memberikan fungsi back-torque limiting serta tuas yang ringan.
DOMINANT ENGINE PERFORMANCE
Intake dan exhaust note dari Ninja ZX-25R dirancang khusus untuk menambah pengalaman yang menyenangkan saat mengendarai Kawasaki bermesin In-Line Four yang memiliki performa luar biasa.
NIMBLE SUPERSPORT-STYLE HANDLING
Composed and confident
The Ninja ZX-25R offers easy maneuverability when riding on city roads, while its excellent supersport handling character can also be felt when sport riding on the circuit. The character of the Ninja ZX-25R is the same as the Ninja ZX-10R and Ninja ZX-6R, which when turning corners, the Rider will feel calm which makes the Rider feel connected to the ground surface, thus increasing confidence and allowing the Rider to explore further, to the limit of his abilities.

WORLD SUPERBIKE CHASIS DESIGN THINKING
The main chassis dimensions (center of gravity position, swingarm pivot position, engine axis position, caster angle, etc.) are inspired by Kawasaki’s World Superbike motorcycle, the Ninja ZX-10RR racing motorcycle. Embedding the WSBK chassis design on a 250cc class motorcycle.
NIMBLE SUPERSPORT-STYLE HANDLING
Trellis Frame & Arched-design swingarm
Designed using Kawasaki’s dynamic stiffness analysis, the lightweight trellis frame provides the balance of chassis strength and flexibility needed to achieve the Ninja ZX-25R’s agile, supersport-style handling. The long-arched swingarm provides the necessary balance between stiffness and flexibility, while allowing the damper to be positioned more centrally and contributing to the stylish, sporty look.

High-Grade Suspension Components
The Ninja ZX-25R uses an ø37 mm inverted fork using SFF-BP (Separate Function Fork – Big Piston) internals. Combining the Showa SFF and BPF concepts, these two advanced forks provide performance for the racetrack as well as daily motorcycle performance.
The Ninja ZX-25RR has a high-end front fork with adjustable spring preload.
NIMBLE SUPERSPORT-STYLE HANDLING
The wide-diameter front disc is gripped by a radial-mount monobloc caliper and coupled with a wide-diameter rear disc provides strong stopping power and superb braking, helping the rider to set precise speeds when cornering and providing good control when riding on city streets.
