2021 Kawasaki Ninja H2 SX SE+ Totalmotorcycle.com Features and Benefits


While the base design starts with the supercharged engine of the Ninja H2™ motorcycle, the numerous changes necessary to achieve the balance of power and fuel efficiency desired for the Ninja H2™ SX SE+ motorcycle essentially resulted in a unique engine. The Balanced Supercharged Engine delivers both exhilarating acceleration and superb fuel efficiency.

Supercharged Intake

  • Kawasaki designed and built centrifugal type supercharger has a high pumping capacity.
  • Planetary gear gets driving force from the crankshaft and spins a 69mm impeller, specially designed using Kawasaki Gas Turbine and Aerospace technology.
  • Since the supercharger design is highly efficient, compressed intake air is minimally heated so no intercooler is necessary.
  • Ram air intake duct feeds the supercharger fresh air in as straight a line as possible to help provide high output.
  • Aluminum intake chamber between supercharger and throttle bodies helps radiate heat to keep intake air cool.
  • ECU-controlled blow-off valve regulates pressure gain in intake chamber when throttle is closed to prevent impeller surging and abnormal vibration.
  • The frontal area of the left-side Ram Air intake is designed to match the airflow requirements of the Balanced Supercharged Engine. The intake duct feeds the supercharger fresh air in as straight a line as possible to contribute to the supercharger’s efficiency.
  • The 69mm supercharger impeller was designed to optimize blade shape and angle for the Ninja H2 SX SE+ motorcyle’s power characteristics. Settings for rpm and airflow volume for maximum efficiency were also optimized.
  • Formed from a forged aluminum block using a five-axis CNC machining center to ensure high precision and durability, the impeller has six blades at the tip expanding to 12 blades at the base. Grooves etched into the blade surfaces help direct airflow.
  • Planetary gear train, specially designed using Kawasaki Gas Turbine and Aerospace technology, is driven by the crankshaft and increases the impeller speed to 9.2 times that of the crankshaft.
  • Aluminum intake chamber between supercharger and throttle bodies helps radiate heat to keep intake air cool. Optimized volume, die-cast construction and diffuser at the mouth of the chamber contribute to overall supercharger efficiency, engine performance and fuel efficiency. A stainless steel net at the end of the diffuser helps smooth airflow.
  • Optimized and irregular intake funnel lengths help boost low- and mid-range performance. The funnels for the outer cylinders are shorter than those in the middle.
  • ECU-controlled blow-off valve regulates pressure gain in intake chamber when throttle is closed to prevent impeller surging and abnormal vibration. Quick valve operation response maintains optimum boost pressure to contribute to power feeling and throttle response.
  • A sound hole in the intake duct allows the rider to enjoy the supercharger’s characteristic chirping.



  • Using race technology developed for the Ninja® ZX™-10R, a two-stage machining process for the cylinder head forms the throat of the intake ports. The valve seat area is bored twice: once along the same path as the throat; then again for the valve seats. The result is smoother intake airflow, which helps reduce intake loss and increases performance.
  • Cam profiles match the airflow requirements of everyday street riding, contributing to the low-mid range focused performance as well as fuel efficiency.
  • Intake and exhaust ports match the airflow to boost low-mid range performance and fuel efficiency.
  • One-piece cylinder/upper crankcase utilizes dummy cylinder head during honing process for more precise cylinder dimensions, which allows use of low-tension piston rings to reduce mechanical loss and boost engine response.
  • High compression ratio increases thermal efficiency and greatly contributes to fuel efficiency.
  • Efficient combustion produces less heat so that the pistons can be cooled by a single oil jet, which allows the oil pump to turn at a slower rate to minimize friction loss. This also allows the engine’s oil volume to be optimized which contributes to weight savings.
  • Large, deep-sump oil pan helps cool oil. Oil pan design ensures the oil pump is always surrounded by oil to prevent cavitation. Additionally, the unique angled shape and position of the oil strainer also helps prevent cavitation during strong acceleration and deceleration.
  • Dual secondary balancers virtually eliminate engine vibration.
  • Exhaust header pipes with connector pipes between cylinders contribute to low-mid range torque and higher fuel efficiency.
  • Light exhaust pre-chamber and compact muffler help centralize weight, which contributes to handling.


Kawasaki DFI®(KP) with Electronic Throttle Valves (ETV)(KP)

  • 40mm Electronic Throttle Valves enable the ECU to control the volume of both the fuel (via fuel injectors) and the air (via throttle valves) delivered to the engine. Ideal fuel injection and throttle valve position results in smooth, natural engine response and the ideal engine output. The system also enhances input to S-KTRC and accommodates the Kawasaki Launch Control and Kawasaki Engine Brake Control (SE model only) features.
  • ETV allows cruise control system to be implemented so that a desired speed can be maintained with a push of a button for added touring comfort.
  • The throttle pulley operates an Acceleration Position Sensor (APS) that uses the ECU to send a signal to a small motor that actually operates the throttle valves. This makes throttle pull very light for reduced rider fatigue.


Cruise Control

  • Electronic cruise control has single-button activation to maintain selected speed, which can also be adjusted with surrounding up/down toggle.



  • Dog-ring transmission uses MotoGP technology in which the gears are fixed to the input transmission shafts and rings move to engage the gears on the output shaft. The result is lighter shifting, improved feel and quicker shifts.
  • Transmission oil jets at every gear mesh and shift fork position provide direct cooling and exceptional lubrication for high durability.
  • Primary gear ratio selected to contribute to fuel efficiency, while helping to reduce the torque load on the transmission gears. First and second gear ratios also contribute to engine manageability in most everyday riding situations.


Kawasaki Quick Shifter (KQS)

  • Contact-less potentiometer-type quick shifter for quick upshifts that enable seamless acceleration.
  • During deceleration when the throttle is completely closed and engine speed is not near redline, KQS automatically controls engine speed to allow downshifting without operating the clutch lever.


Assist & Slipper Clutch

  • Using the rotational forces of the clutch hub and pressure plate, the clutch is forced together during acceleration (Assist function) so that fewer and lighter clutch springs can be used for a lighter feel at the lever. During high back-torque, such as when too low of a gear is selected during downshifting, the Slipper function allows some clutch slippage to help prevent engine lock-up, stalling and rear wheel hop.
  • Judder spring component helps prevent judder when the clutch is disengaged.





  • Kawasaki’s cutting-edge electronics have always excelled on the track due to the highly sophisticated programming that gives the ECU an accurate, real-time picture of what the chassis is doing using minimal software. With a Bosch IMU and the latest evolution of Kawasaki’s proprietary dynamic modeling software, the Ninja H2 SX SE+ motorcyle’s electronic management technology is next level, changing from setting-type and reaction-type systems to feedback-type systems.


Inertial Measurement Unit (IMU)(KP)

  • The IMU measures inertia along 5 axes: acceleration along longitudinal, transverse and vertical axes, roll rate, and pitch rate. The yaw rate is calculated by the ECU using Kawasaki’s patented software to provide six-axis chassis attitude input of lean angle and acceleration/deceleration force for more precise management of the electronic riding aids.
  • The IMU allows KTRC to incorporate more feedback to help maximize acceleration when exiting corners on the track.
  • Unlike competitors’ systems that have pre-set limits, Kawasaki’s proprietary race-developed software enables the Ninja H2 SX SE+ to have a dynamic system that has a higher level of chassis awareness and adapts to changing conditions such as rider inputs, vehicle attitude, and pavement conditions.


Kawasaki Cornering Management Function

  • Corner Management Function uses both KIBS and KTRC to assist riders in tracing their intended line through a corner by suppressing the tendency for the bike to stand up while braking in a turn. The IMU helps the system maintain optimum hydraulic pressure based on the bike’s lean and pitch angles.


Kawasaki Launch Control Mode (KLCM) (SE Model Only)

  • Designed to assist the rider by optimizing acceleration from a stop, KLCM electronically controls engine output to help prevent wheelspin and thereby minimize front end lift when launching from a standstill.


Kawasaki Traction Control (KTRC)

  • Mode 1 prioritizes forward acceleration, while Mode 2 offers a balance between acceleration performance and rider reassurance. Mode 3 provides rider reassurance by facilitating smooth riding on slippery surfaces.
  • The system confirms conditions every 5 milliseconds and uses ignition cut and airflow control (via the electronic throttle valves), enabling extremely quick reaction.
  • Using complex analysis, the system monitors traction conditions. By acting before slippage exceeds the range for optimum traction, drops in power can be minimized, resulting in ultra-smooth operation.


Integrated Riding Modes:

Sport, Road, Rain, Rider (manual)

  • All-inclusive modes that link KTRC, Power Mode and KECS allow riders to efficiently set traction control, power delivery and suspension character to suit a given riding situation.
  • Riders can choose from three settings (Sport, Road, Rain) or a manual setting (Rider). In the manual Rider mode, each of the systems can be set independently.


– Sport: enables riders to enjoy sporty riding on winding roads.

– Road: offers comfortable riding over a wide range of situations, from city riding to highway cruising and rural roads.

– Rain: offers rider reassurance when riding on a wet road surface.


  • KIBS settings are adjusted according to the KECS damping (Rider Mode) setting selected. The riding mode can be changed while riding, using the button at the left side of the handlebar.


Kawasaki Engine Brake Control

  • The Kawasaki Engine Brake Control system allows riders to select the amount of engine braking they prefer.
  • When Kawasaki Engine Brake Control is activated (by selecting “LIGHT” in the settings), the effect of engine braking is reduced.



  • Swingarm mounting plate is bolted to the back of the engine to make it part of the frame. This eliminates frame cross members to help keep the frame light and enables the chain tension generated by the high-output engine to be efficiently transferred to the rigid engine block.
  • Centerstand provides upright parking and helps ease maintenance.



  • Based on the semi-active system introduced on the 2018 Ninja® ZX™-10R SE motorcycle, KECS electronically controls damping to the cartridge front fork and BFRC lite (Balance Free Rear Cushion) rear shock that adapts to road and riding conditions in real time to provide the ideal amount of damping for the current condition.
  • Combining advanced, mechanical components with sophisticated electronic control technology, KECS offers the suppleness to handle a wide range of street riding situations and the firm damping for more sport-oriented riding so that the tires feel planted and enhance cornering confidence.
  • Damping is adjusted electronically to suit vehicle speed and suspension stroke speed. Deceleration is also considered to help control (not eliminate) the natural pitching that occurs under braking.
  • A solenoid valve controls damping with direct (single-stage) actuation. This results in an extremely quick reaction time of one millisecond – much quicker than systems that rely on step-motors, or those that use pilot valves (two-stage actuation) that slow the system’s responsiveness. The quick reaction time makes KECS ideal for sport riding applications, where natural feeling is crucial to feeling at one with the bike.
  • Built-in stroke sensors on both the fork and rear shock – the same used on the Ninja ZX-10R SE – provide real-time stroke speed and compression information. The sensor coils provide input to the KECS ECU every millisecond, which is complemented by information provided by the IMU (acceleration/deceleration) and the FI ECU (vehicle speed) every 1/100th of a second. The KECS ECU then directs current to the solenoids to adjust damping as required by the situation.
  • Base damping character is set according to the integrated Riding Mode (Sport, Road, Rain, Rider (manual)) selected. KECS then adjusts to the road surface environment in real time to provide the ideal damping, taking into account vehicle speed, stroke speed and deceleration.
  • Rear preload is also electronically set. Riders can choose from three payload modes (each with +5/-5 adjustment):
  • Supersport-sourced suspension components deliver a combination of ride comfort and sport performance ideal for street and long-distance riding.
  • The bottom of the rear shock is mounted to New Uni-Trak® linkage that helps provide excellent rear tire feeling to the rider.
  • Both the linkage and top of the shock are mounted to the Swingarm Mounting Plate, which eliminates frame cross members to save weight.
  • Uni-Trak® linkage rear suspension system provides progressive action to the rear shock so that small bumps are damped lightly and large bumps get heavy damping for a smoother ride and better steering and handling.
  • The Ninja H2™ SX SE+ motorcycle utilizes a single-sided swingarm. Composed of forged and pressed aluminum parts, it is highly rigid and light weight. It allows more room on the right side of the motorcylce for optimized exhaust shape.


High-Performance Brakes with Kawasaki Intelligent anti-lock Brake System (KIBS)

  • Brembo Stylema monobloc calipers are lightweight and help cool the brake fluid for better performance.
  • Radial-mounted 4-piston brake calipers, radial-pump brake master cylinder and big 320mm brake discs provide impressive braking performance and superb feel.
  • Rear brake features twin piston caliper that clamp a 250mm disc.
  • KIBS high-precision anti-lock brake system provides smooth feedback and minimal lever movement for added braking confidence.
  • The engine ECU communicates with the compact ABS ECU (which monitors wheel speed and front caliper hydraulic pressure) to provide highly precise brake pressure control. The high precision control means brake performance is not reduced due to excessive pressure drops and there is a more consistent lever feel instead of sharp lever pulses felt with conventional ABS systems.



  • Designed for both sport riding and comfort, the riding position is not as far forward-leaning as the Ninja® ZX™-14R motorcycle yet not as upright as the Ninja® 1000 motorcycle. The Ninja H2™ SX SE+’s riding position offers a more relaxed bend for both the elbows and knees compared to the Ninja® ZX™-14R.
  • Both the front and rear seats provide long-distance comfort.
  • Slim design of the front seat helps the rider’s feet reach the ground, while the rear seat has a wide, flat surface for passenger comfort.
  • Ergonomically designed passenger grab rails and footpeg mounts provide integrated mounting points for accessory KQR saddlebags.
  • Heated grips add comfort in cold weather.


Aggressive Styling

  • Front cowl resembles that of the Ninja H2™ and prominently displays the Kawasaki River Mark emblem.
  • Full fairing helps shield the rider yet isn’t so large as to create adverse drag at highway speeds.
  • Large fairing ducts help reveal the supercharged engine and help extract heat from the engine compartment.
  • Forward-slanted “High Velocity Lines” traced by the side cowls, fins, tail cowl and muffler present the image of speed even when the Ninja H2™ SX SE+ is at a standstill.
  • From the recessed headlight to the sleek taillight, which displays a dual “H” at start-up, all lights are LED.
  • LED cornering lights feature three fixed-direction lights on each side of the fairing. The lights illuminate in order based on lean angle to provide a wider beam of light in the direction the bike is travelling.
  • Larger windscreen helps deflect more wind from the rider’s upper body.


Highly Durable Paint

  • Kawasaki’s Highly Durable paint has a special coat that allows minor scratches to self-repair to help the paint maintain its high-quality finish.
  • Soft and hard segments in the paint work together like a chemical spring, creating a trampoline effect that absorbs impacts.



  • High-grade full color multi-meter display features TFT (thin-film transistor) technology to ensure a level of visibility previously unattainable. The screen’s background color is selectable (black or white), and screen brightness adjusts automatically to suit available light. In addition to scrollable multi-function windows, two display modes offer riders a choice of how they want their information presented.


RIDEOLOGY THE APP Smartphone Connectivity

† Do not operate smartphone while riding

  • A Bluetooth® chip built into the instrument panel enables riders to connect to their motorcycle wirelessly. Using the smartphone application “RIDEOLOGY THE APP,” a number of instrument functions can be accessed, contributing to an enhanced motorcycling experience.


Available functions:

Vehicle Info: information such as fuel gauge, odometer, maintenance schedule, etc can be viewed via the smartphone.

Riding Log: GPS route information as well as vehicle running information can be logged and viewed via the smartphone.

Telephone notices: when a call or mail is received by the smartphone, this is indicated on the instrument display.

General Settings: general instrument display settings (such as preferred units, date, date format, etc) can be adjusted via the smartphone.

Vehicle Settings: Riding Mode (Road, Sport, Rain, Rider) can be set in advance on the smartphone and uploaded when in proximity of the bike, as can riding support systems (like KQS) and the payload mode.

  • Once vehicle information has been downloaded to the app, it can be viewed on the smartphone. Available information includes: odometer, trip A, trip B, fuel gauge, remaining range, average gas mileage, average speed, max lean angle (right/left), battery voltage, Kawasaki service reminder, oil change reminder, etc.
  • Detailed riding logs including GPS information and vehicle running information can be recorded. While riding, the app tracks vehicle speed, rpm, gear position, throttle position, front brake fluid pressure, acceleration/deceleration, current mileage, and coolant temperature from moment to moment. Once the riding log has been saved, riders can review these items in a graphic-style display at any point along the route. The app can also display a ride summary, with information that may include: route travelled, total distance, total time, gas mileage (best/average), speed (best/average), max lean angle (right/left), etc. For either display mode, riders can select which items are displayed, and can arrange them in their preferred order.
  • When riding with the app ON the bike and smartphone are always connected. When the engine is turned off, the latest riding information stored by the app may be viewed on the smartphone. Any vehicle setting changes made via the app while the engine is off, or while out of range, cannot be uploaded until the ignition is turned on and the smartphone is in range with the app ON. General settings can only be updated via the app when the bike and smartphone are connected.
