2023 Kawasaki Z650RS KRT Totalmotorcycle.com Features and Benefits

Compact 649cc Twin-Cylinder, DOHC Engine
• Tuned to deliver strong, smooth and responsive power, especially in the low-to-mid-range, for rider-friendly power characteristics that facilitate control and inspire confidence over a wide range of riding conditions.
• Camshafts have short operating angle and valve overlap for optimum performance in the low-to-mid-range.
• Optimized intake port shape also helps boost low and midrange response and performance.
• Slim airbox contributes to low and mid-range power feeling and contributes to the overall slim design of the bike.
• Exhaust system has a short header to boost top-end power while the sleek muffler’s internal construction enhances low-to-mid-range power delivery.
• Muffler is mounted below the engine to help lower the center of gravity and aid weight centralization.
• Kawasaki Air Management System(KP) (KAMS) radiator fan cover helps direct hot engine air down to the ground and away from the rider.
• Compact parallel twin engine helps reduce the dimensions of the entire motorcycle to keep it small and nimble.
• Triangular crank and transmission shaft layout makes the engine very short from front to back, a semi-dry sump(KP) oil system reduces overall engine height, while the narrow pitch of the chrome composite(KP) plated aluminum cylinders helps reduce engine width.
• 180-degree crankshaft plus balancer shaft for extremely smooth engine operation.
• Oil jets in the connecting rod big ends spray oil on the undersides of the pistons to aid cooling.

Digital Fuel Injection(KP)
• 36mm Keihin throttle bodies contribute to the strong low-to-mid-range power and feature dual throttle valves(KP) for optimum performance and rideability. The sub throttles, located behind the main throttle valves, are controlled by the ECU so that the DFI® system has precise throttle response.
• Precise fuel delivery through the fine atomizing injectors plus exhaust catalyzer significantly reduce emissions.
• Automatic fast idle system makes starting and warm-up easy.

6-Speed Transmission
• Cassette-style transmission puts the transmission shafts and shift drum into a compact layout which helps reduce overall engine size.
• Positive Neutral Finder is a Kawasaki exclusive user-friendly feature that allows the rider to easily shift from first gear and only into neutral when the bike is at stop.

Horizontal Back-link Rear Suspension
• The linkage is placed atop the swingarm and helps make room for the under-engine muffler for better mass centralization.
• Rear shock is further away from the exhaust so that its operation will not be affected by exhaust heat.
• Gull-wing swingarm also allows clearance for the muffler while contributing to light, natural handling.

• High-tensile steel trellis frame has optimized dimensions and wall thicknesses to reduce frame weight and contribute to extremely light handling.
• Frame components are arranged so that the lines of the frame are as straight as possible. When bends were necessary their angles were as small as possible, resulting in a design that disperses stress extremely well.
• Three-point, rigidly mounted engine and footpeg stays are used as stressed members to further contribute to weight reduction.

Triple Petal Design Brake Discs
• Available Anti-Lock Brake System (ABS) helps assist braking under certain conditions and features a small Bosch 9.1M control unit to save space and weight.
• Nissin brake calipers have a sporty image and contain front and rear brake specific pads; the front providing strong initial bite and the rear offering optimum control and high overall brake force.
• Front brake calipers have large 27mm pistons for excellent brake feel.
• Petal design offers improved cooling and warp resistance.

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 gear is selected, the Slipper function allows some clutch slippage to help prevent engine lockup and stalling, and rear-wheel hop.

Spoke-Style Cast Wheels
• Original cast wheels feature flat spokes designed to look like classic wire-spoked wheels. Designed using Kawasaki’s advanced analysis technology,
the wheels offer a balance of light weight and stylish looks, contributing to both handling and a design suited to the retro category.
• Low unsprung weight contributes to the light, natural handling.
• Dunlop Sportmax Roadsport 2 tires further contribute to the light handling

Relaxed Riding Position
• Wide, flat handlebar and a relaxed riding position puts the rider in a natural, comfortable position that helps inspire confidence for a wide range of riders.
• Wide, flat handlebar contributes to the retro sport styling while offering a wide grip to facilitate control.
• The upper-triple clamp is positioned 20 mm higher than the Z650, contributing to the higher handlebar position and a more upright riding position. Relative to the Z650, the handle grips are 50 mm higher and 30 mm back (closer to the rider).
• A wide 35° steering angle assists with low-speed maneuvering.
• The low seat height and slim overall design helps riders to put both feet on the ground when stopped, further instilling confidence.
• Footpeg position offers a relaxed knee bend, contributing to rider comfort.
• Slim fuel tank provides a comfortable fit for gripping with the knees.
• Stepped seat offers a wide seating area for good ride comfort. The seat is slimmer at the front to help rider’s reach to the ground.
• Rubber-mounted handlebar helps reduce vibration transmitted through the handle grips and to the mirrors.
• Both clutch and brake levers are 5-way adjustable to help accommodate a variety of hand sizes for increased comfort.
• Rider and passenger footpegs feature rubber pads. A hard compound combined with hollow center helps reduce vibration felt through the footpegs.

Modern Retro Styling
• A blend of retro and modern designs, the round LED headlight casts a bright, white light. It features two chambers for low and high beam, both with position lamps to ensure the whole lamp appears lit, like a retro-style bulb headlight. The grooved design on the thick headlight ring adds a modern touch.
• Retro-style fuel tank design uses edges dividing the top and sides of the tank to emphasise its compact size.
• Simple design of the side covers contributes to the modern retro styling.
• Unlike the upswept tail of the Z650, the tail of the Z650RS traces a horizontal line, contributing to the bike’s flat stance.
• The original-design stepped seat is unique to the Z650RS.
• The oval design of the LED taillight is an homage to Kawasaki’s old-school Z models. Unlike standard LED taillights that appear as a collection of dots, the Z650RS’ LED taillight lights up as a solid surface, much like a bulb taillight, creating a design that is both retro and modern.

Dual-Dial Instrumentation with Multi-Function LCD
• Analogue-style speedometer and tachometer dials are complemented by a multi-functional LCD screen, balancing retro-style looks with modern functionality.
• Bullet-shaped dial cases add to the retro appearance, while the modern typeface used on the dial faces add a contemporary touch.
• LCD screen features white letters on a black background, adding to the instrument cluster’s sporty, modern appearance.
• Gear position indicator increases shifting precision and confidence.
• In addition to the gear position indicator, display functions include: odometer, dual trip meters, fuel gauge, remaining range, current and average fuel consumption, coolant temperature, clock and the

Economical Riding Indicator.
• The Economical Riding Indicator appears on the LCD screen when fuel consumption is favourable. Paying attention to conditions that result in the
mark appearing can assist riders to maximize fuel efficiency.
