Dual Throttle Valves
Late-model sport bikes often use large-bore throttle bodies to generate high levels of power. However, with large diameter throttles, when a rider suddenly opens the throttle, the unrestricted torque response is anything but gentle and often more than the rider can handle. Dual throttle valve technology was designed to tame engine response while contributing to performance.
On most fuel injected models, throttle bodies have only one throttle valve per cylinder. On models with dual throttle valves, there are two throttle valves per cylinder: in addition to the main valves, which are physically linked to the throttle grip and controlled by the rider, a second set of valves, opened and closed by the ECU, precisely regulates intake airflow to ensure a natural, linear response. With the air passing through the throttle bodies becoming smoother, combustion efficiency in improved and power is increased.
Like other Kawasaki engine management technology, Dual Throttle Valves were designed with the philosophy of "following the rider's intention, while providing natural-feeling support." They are featured on many Kawasaki models.
Economical Riding Indicator
Using high-precision electronic control for engine management, Kawasaki models can achieve a high level of fuel efficiency. However, fuel consumption is greatly affected by throttle use, gear selection, and other elements under the rider's control.
The Economical Riding Indicator is a function that indicates when current riding conditions are consuming a low amount of fuel. The system continuously monitors fuel consumption, regardless of vehicle speed, engine speed, throttle position and other riding conditions. When fuel consumption is low for a given speed (i.e. fuel efficiency is high), an "ECO" mark appears on the instrument panel's LCD screen. By riding so that the "ECO" mark remains on, fuel consumption can be reduced.
While effective vehicle speed and engine speed may vary by model, paying attention to conditions that cause the "ECO" mark to appear can help riders improve their fuel efficiency - a handy way to increase cruising range. Further, keeping fuel consumption low also helps minimise negative impact on the environment.
ABS (Anti-lock Brake System)
Sudden over-application of the brakes, or braking on low-grip surfaces (surfaces with a low coefficient of friction) such as wet asphalt or manhole covers may cause a motorcycle's wheel(s) to lock up and slip. ABS (Anti-lock Brake System) was developed to prevent such incidents. Kawasaki ABS systems are controlled by high precision and highly reliable programming formulated based on thorough testing of numerous riding situations. By ensuring stable braking performance, they offer rider reassurance that contributes to greater riding enjoyment.
And to meet the special requirements of certain riders, specialised ABS systems are also available. For example, KIBS (Kawasaki Intelligent anti-lock Brake System) is a high-precision brake system designed specifically for supersport models, enabling sport riding to be enjoyed by a wider range of riders. And by linking the front and rear brakes, K-ACT (Kawasaki Advanced Coactive-braking Technology) ABS provides the confidence to enjoy touring on heavyweight models. Kawasaki is continually working on the development of other advanced ABS systems.
Assist & Slipper Clutch
Based on feedback from racing activities, the Assist & Slipper Clutch uses two types of cams (an assist cam and a slipper cam) to either drive the clutch hub and operating plate together or apart.
Under normal operation, the assist cam functions as a self-servo mechanism, pulling the clutch hub and operating plate together to compress the clutch plates. This allows the total clutch spring load to be reduced, which translates to a lighter clutch lever feel when operating the clutch.
When excessive engine braking occurs as a result of quick downshifts (or an accidental downshift) the slipper cam comes into play, forcing the clutch hub and operating plate apart. This relieves pressure on the clutch plates to reduce back-torque and help prevent the rear tyre from hopping and skidding. This race-style function is particularly useful when sport or track riding.
Horizontal Back-link Rear Suspension
Compared to Kawasaki's traditional Uni-Trak rear suspension, which mounts the shock unit vertically, with Horizontal Back-link rear suspension, the shock unit is almost horizontal. Kawasaki's original suspension arrangement locates the shock unit very close to the bike's centre of gravity, greatly contributing to mass centralisation. And because there is no linkage or shock unit protruding beneath the swingarm, this frees up space for a larger exhaust pre-chamber (an exhaust expansion chamber situated just upstream of the silencer). With a larger pre-chamber, silencer volume can be reduced, and heavy exhaust components can be concentrated closer to the centre of the bike, further contributing to mass centralisation. The result is greatly improved handling.
Another benefit is that the shock unit is placed far away from exhaust heat. Because it is more difficult for heat from the exhaust system to adversely affect suspension oil and gas pressure, suspension performance is more stable. Horizontal Back-link rear suspension offers numerous secondary benefits like this.
Sugomi performance ensures that riding the Z650L is a treat for the senses. A responsive, torqueful engine character and nimble, lightweight chassis offer sporty riding excitement that new and more experienced riders alike will enjoy.
Tuning of the 649 cm³ Parallel Twin engine focused on achieving a throttle response that balanced a powerful feeling and a quick-revving character. To optimise performance for everyday riding, care was taken to maximise low-mid range torque. When opening the throttle, riders will notice an extremely smooth and powerful engine character that offers both a high level of control when making minute throttle adjustments and a gratifying rush of acceleration in the lower rpm ranges. This tuning also benefits fuel economy.
Parallel-Twin Engine Tuned for Low-Mid Range Power & Torque
Performance and feel were optimised for the mid-range (3,000-6,000 min-1). However, in the low-rpm range (below 3,000 min-1) power delivery is very smooth, and even above 6,000 min-1 power and torque curves continue on without dropping off suddenly.
Digital Fuel Injection
Liquid-cooled, DOHC, 8-valve 649 cmÂ³ Parallel Twin with fuel injection delivers smooth, responsive performance, especially in the low and medium rpm ranges. The strong low-end focus lends itself to sporty riding, but also translates to rider-friendly power characteristics that facilitate control and inspire confidence in new riders.
Simple, sleek silencer design adds to the bikes's overall slim design. Under-engine muffler improves mass centralisation and lowers the bike's centre of gravity. Muffler internal construction and catalyser layout ensure clean emissions that will pass stringent Euro 4 regulations. The muffler's 33 mm diameter tail pipe also contributes to strong low-mid range performance and response.
Patented radiator fan cover located behind the radiator directs hot air down and away from the rider, significantly increasing comfort when stuck in heavy traffic. Redirecting the air also helps keep the tank, frame and other parts that contact the rider cooler, further increasing rider comfort.
Horizontal Back-link Rear Suspension
Horizontal Back-link rear suspension offers a progressive character. Compared to link-less type suspension, it delivers a better balance of sporty performance and ride comfort. Rear suspension positions the shock unit and linkage above the swingarm. This arrangement contributes to mass centralisation, while ensuring that the suspension is located far enough from the exhaust that operation is not affected by heat.
All-New Trellis Frame
One of the key components realising Z650L's light weight (noticeable as soon as the bike is lifted off its side-stand), the all-new frame weighs only 15 kg and contributes significantly to the bike's light, nimble handling. Components of the high-tensile steel trellis frame follow the ideal pipe line. The lines of the frame were made as straight as possible, and when bends were necessary their angles were made as small as possible, resulting in a design that disperses stress extremely well.
Light, Strong Swingarm
Kawasaki's new in-house analysis technology was also used in the swingarm. Similar to the frame, the line from the pivot to rear axle was made as straight as possible. The lightweight design of swingarm (4.8 kg) contributes to the bike's light, natural handling.
The Z650L's low weight and low seat height both contribute to manoeuvrability, whether walking beside the bike, or foot peddling in a parking lot. The easy-to-manage engine response and strong low-end torque further facilitate low-
Relaxed, Sporty Ergonomics
Wide, flat handlebar and a relaxed, sporty riding position allows riders to fully capitalise on the Z650LÃ¢â‚¬â„¢s sporty street riding potential. Thanks to the low seat height and the bikeÃ¢â‚¬â„¢s slim overall design, itÃ¢â‚¬â„¢s easy to keep both feet firmly on the ground when stopped, an important consideration for many riders. The low 790 mm seat height accommodates riders spanning a wide range of heights, enabling them to ride with confidence.
Sport Riders Seat
The sport riders seat is slim at the front facilitating the rider's reach to the ground. Seat bracket is rubber-mounted at the front to reduced vibration transferred through the seat. Handlebar is rubber-mounted to reduce vibration transmitted through the handle grips and to the mirrors.
Both the clutch and front brake lever are 5-way adjustable, able to accommodate a variety of hand sizes for increased comfort. Rider and passenger footrest feature rubber pads. Harder rubber combined with hollow centres were designed to reduce vibration felt through the footpegs.
Eye Catching Z Styling
From its front cowl adorned with meter cover to its compact tail cowl, the Z650L's head-turning design exudes a functional beauty. Complementing sugomi design elements (crouching stance, low-positioned head and upswept tail) that give it an instantly recognisable silhouette, its condensed appearance is emphasised by slim, close-fitting bodywork designed to give the bike a light, nimble image that reflects its sporty performance.
Petal disc brakes with ABS
Dual 300 mm front petal disc brakes and 220 mm rear petal disc look great and deliver plenty of braking power while contributing to the bikes sporty image. Dual-piston front calipers, master cylinder and brake pads offer superb brake touch and control. In addition to the very effective petal disc brakes, customers looking for an added degree of reassuring braking performance are advised that the Z650L has standard front and rear ABS braking systems.
Compact Multi-Function Instrumentation
Stacked instrument cluster features an easy-to-read layout. Analogue-style tachometer features a gear position indicator at its centre and sits atop a multi-function LCD screen. Gear position indicator increases shifting precision and confidence, while also lending to the Z650L's sporty image. Tachometer offers three selectable display modes, allowing riders to tune their instrumentation to suit their preference. The tachometer also doubles as a shift up indicator, flashing at the set rpm. Riders can set the shift-up timing between 5,000 and 11,000 rpm in 500 rpm increments. The shift indicator function may also be turned OFF. LCD screen features a negative display (white letters on a black background), adding to the instrument cluster's sporty, modern appearance. In addition to the digital speedometer and gear position indicator, display functions include: odometer, dual trip meters, fuel gauge, remaining fuel range, current and average fuel consumption, coolant temperature, clock and the Economical Riding Indicator.
LED Tail Lights
Ensuring the Z650L is not mistaken for anything other than Kawasaki Supernaked when viewed from behind, its sharp LED taillight lights up in "Z" pattern, contributing to the sporty image and the strong Z identity.
