The Top Contender in the Middleweight Category

Power. Speed. Handling. Dominance. The Ninja® ZX™-6R packs all this and more underneath its 599 cc engine, twin spar aluminum frame and advanced Showa suspension. Whether you're a street rider or a racer, this bike packs the kind of potent strength that will satisfy even the most discriminating enthusiasts.

The 2012 ZX-6R carries on the tradition of middleweight dominance – started back in 1985 with the revolutionary ZX600-A1 – to a staggering level. And in today's ultra-competitive 600 supersport market, where technology, racetrack success and streetbike acumen can change dramatically year by year, that's saying a lot. Don't believe us? Then ask the many top-level magazines and web sites that picked the current-spec ZX-6R as Best Middleweight. It was an absolutely dominating 600 shootout performance – and one sure to be replicated in 2012 due to the ZX-6R's track-honed DNA and seamless all-around capability.

Standard Features

Key Features
 Lean physique, low mass, forceful power, controllable power delivery and precise overall control  
 599 cc inline-four with DFI® is lightweight yet powerful  
 Fully adjustable front and rear suspension includes the Showa Big Piston Front fork (BPF), which offers fantastic wheel and chassis control  
 Lightweight aluminum chassis places the engine in the ideal location for excellent handling and rider feedback  
 Radial-mounted front brake calipers and radial-pump front brake master cylinder offer superb braking power and control  
 Race-quality adjustable Öhlins steering damper comes standard  
 Slipper-type back torque-limiting clutch offers quick downshifts without chassis agitation  
 Named one of Cycle World magazine’s 10 best bikes  
Lightweight Engine
 Camshafts are made of chrome-moly steel  
 Lightweight magnesium engine covers are standard  
 Lightweight top injector mounting plate  
 Lightweight transmission gears and gear dogs  
 Lightweight oil pump and starter gears  
 Inlet pressure pulse monitor does away with cam angle sensor, further contributing to lightness  
 Cassette-type transmission makes it easy to quickly swap gear ratios, reducing set-up time at the track  
Massive Mid-range Performance
 Double-bore velocity stacks feature inlets at two different heights for increased performance in both the mid and high-rpm ranges  
 Cam and tappet nitriding enables high-load cam profiles for maximum performance  
 Crown-finished pistons  
 Molybdenum-coated piston skirts for reduced friction and engine break-in  
 Low-tension piston rings reduce mechanical losses  
 Advanced cam chain guides stabilize chain motion and further reduce mechanical losses  
 Exhaust collector layout contributes to superb low and mid-range performance while maintaining high-rpm performance  
Precise Throttle Control
 Cylindrical guides in the top of the air cleaner box ensure accurately sprayed fuel mist from the secondary injectors into the intake funnels, improving combustion efficiency  
 Long throttle bodies between oval sub-throttles and round main throttles yield a smooth intake transition for reduced inlet turbulence and increased efficiency  
 Advanced cylinder porting delivers excellent cylinder filling and scavenging  
 High-current secondary coil circuitry for optimum combustion efficiency  
Lightweight Chassis
 Twin spar aluminum frame is both lightweight and rigid, and places the engine in the optimum position for superb handling and rider feedback  
 The sub-frame is a two-piece aluminum die-casting consisting of a front and rear section  
 The 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  
Tuned Chassis Balance and Mass Centralization
 Frame stiffness around the swingarm pivot and the rear engine mounts optimizes front-rear rigidity balance  
 Engine is rotated forward around the output shaft for steeper intake angle and excellent CG  
 Exhaust layout with a short side muffler keeps the weight low  
 Exhaust pre-chamber further contributes to mass centralization  
Ergonomics and Chassis Feedback
 Seat-peg-bar relationship places handlebars close to the rider; bars are angled for a highly intuitive and comfortable riding position  
 Fuel tank is flared around its top, similar to the ZX™-10R, providing a large contact patch for excellent rider feedback  
 Slim-waisted fuel tank makes it easy for the rider to grip the tank with their knees, or to hang off in turns  
 Sculpted seat allows the rider to shift their body far back on the rear seat step, helping to reduce rider fatigue  
 Steep rake angle for quick steering response and enhanced communication from the front tire  
 Rear brake master cylinder reservoir forward of the swingarm mount frees up space around the footpeg for simplicity and weight savings  
Low Seat Height
 Narrow rear sub-frame makes it easy to reach the ground  
 Front of seat is narrow and low for a slim riding position and a short reach to the pavement  
Advanced Suspension
 ZX-6R features Showa’s Big Piston Front fork (BPF) design for fantastic wheel and chassis control  
 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  
 Radial calipers and 300 mm petal-type discs up front offer superb braking power and control  
 220 mm rear petal-type disc  
 Rear brake lever is mounted coaxially with the footpeg for excellent mid-stroke braking efficiency and optimum feel  
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
 Highly evolved fairing offers great wind protection and minimizes cross-wind effects  
 Position lamps are integral to the projector beam headlights  
 One-piece fender offers excellent aerodynamics  
 Inner fender above the swingarm helps to reduce turbulence and keeps the undertail clean  
 Front brake hose routing with a three-way joint at the lower triple clamp facilitates bleeding air from the brake lines  
 Instrument panel gives the rider plenty of information at a glance
