2009 Kawasaki Ninja ZX6R Features

2009 Kawi Ninja ZX6R Features
Key Feature
- New leaner physique with a major reduction in weight and improved power delivery offer more precise control, lighter handling and better acceleration
Lightweight engine
- Camshafts are now made of SCM – saving approximately 400g
- Lightweight magnesium engine covers are standard and save approximately 610g over aluminum units
- Revised top injector mounting plate saves approximately 80g
- Narrower transmission gears and revised gear dog shape provide a 170g weight savings, without compromising rigidity
- Oil pump and starter gears are machined to use less metal, shedding approximately 70g
- New inlet pressure pulse monitor enables deletion of the cam angle sensor, further contributing to engine weight reduction
- Coolant reservoir relocated and redesigned, the new shape and shorter tube save approximately 150g
- Revised and relocated heat pads contribute another 170g to weight savings
- Reshaped secondary air passages through the cylinder head contribute to more efficient cleaning of exhaust emissions
- Cassette-type transmission makes it easy to quickly swap gear ratios, reducing set-up time at the track

Increased mid-range performance
- New double bore velocity stacks feature inlets at two different heights, increasing performance in both the mid- and high-rpm ranges
- Increased durability from optimized cam nitriding and tappets enable high-load cam profiles, which improve overall performance
- Pistons have new profiles and improved crown finishing
- Molybdenum coated piston skirts reduce friction and help with engine break-in
- Piston rings with less tension reduce mechanical loss
- Revised cam chain guides stabilize chain motion, further reduce mechanical loss
- New exhaust collector layout contributes to improved low and mid-range performance while maintaining high-rpm performance

More precise throttle control
- Cylindrical guides added to the top of the air cleaner box ensure more accurately sprayed fuel mist from the secondary injectors into the intake funnels, improving combustion efficiency
- Longer throttle bodies increase the distance between oval sub-throttles and round main throttles 10mm, yielding a smoother transition, which reduces inlet turbulence and increases efficiency
- Revised cylinder porting delivers improved cylinder-filling and scavenging
- New ignition coils have 12% greater secondary coil current for improved combustion efficiency, adding to the improved performance

Lightweight chassis
- The sub-frame is a 2-piece aluminum die-casting consisting of a front and rear section
- The new lightweight sub-frame is very narrow, for a compact and slim rear end
- Intake resonator box and supports for the instrument panel and mirrors are unitized with the Ram Air duct, contributing to weight savings and increased rigidity
- Frame brackets revised to reduce overall number of parts, which also contributes weight savings.
- New throttle housing material saves approximately 30g

Revised chassis balance and mass centralization
- Revised frame stiffness around the swingarm pivot and the rear engine mounts optimizes front-rear rigidity balance
- Engine is mounted with a steeper cylinder bank angle. Rotated around the output shaft, the engine’s CG is 16mm higher
- New exhaust layout with a short side muffler lowers weight previously located under the seat
- An exhaust pre-chamber further contributes to mass centralization

Ergonomics and chassis feedback
- Seat-pegs-bar relationship was adjusted slightly, with the handlebars moved closer to the rider and turned in slightly for a more intuitive riding position
- Fuel tank profile is more flared around its top, similar to the ZX-10R, providing a larger contact patch which contributes to improved rider feedback
- Slim, waist on fuel tank makes it easy for the rider to grip the tank with his knees or to hang off in turns

- Front to back, the new seat is shorter, allowing the rider to shift his body farther back on the rear seat step, helping to reduce rider fatigue
- Steeper rake angle quickens steering response and enhances communication from the front tire
- Relocating the rear brake master cylinder reservoir forward of the swingarm mount frees up space around the footpeg, enabling a reduction of parts and contributing to weight savings

Lower seat height
- New rear sub-frame is narrower, making it easier to reach the ground
- Front of seat is narrower and seat height is approximately 10mm lower, for a slimmer riding position and a shorter reach to the pavement

Advanced suspension
- ZX-6R features the first production-use of Showa’s new Big Piston Front fork (BPF) design
- The BPF eliminates many of the internal components used in a cartridge-type fork, simplifying construction and resulting in lighter overall fork weight
- The large-diameter of the BPF’s internal piston allows a reduction in damping pressure, for better feedback and smoother action
- The ZX-6R swingarm uses many of the same parts as the ZX-10R; both left and right inner plates, the left outer plate, rear stand bosses, brake caliper stopper, chain guard and swingarm pivot shaft
- Greatly improves braking and initial corner turn-in

- New 220mm rear petal disc is 10mm larger
- Revised rear brake lever is now mounted coaxially with the footpeg for increased mid-stroke braking efficiency and improved feeling

Race-quality steering damper
- A race quality adjustable Öhlins steering damper with relief valve and twin-tube design is fitted as standard equipment

Additional Features
- New fairing offers better wind protection and was designed to minimize the effects of cross winds
- Position lamps are now integral with the projector beam headlights; the new Ninja ZX-6R now features dual position lamps like the ZX-10R
- New one-piece fender (previously a three-piece construction) offers improved aerodynamics
- New inner fender above the swingarm helps to reduce turbulence and keep the undertail clean
- Revised front brake hose routing with a three-way joint at the lower triple-clamp facilitates bleeding air from the brake lines
- Similar in design to that of the ZX-10R, the new instrument panel gives at-a-glance information to the rider
