Power. Speed. Handling. Dominance. Sometimes, bikes just come with all the elements that make for a perfect sports bike. In a nutshell, that’s what you get with the Kawasaki Ninja ZX-6R. It’s got the kind of potent strength that will satisfy even the most discriminating enthusiasts. For the 2012 model of the ZX-6R, you can expect the same tradition of middleweight performance that harkens back to the day of the ZX600-A1.
The ZX-6R is powered by Kawasaki’s famous 599cc 16-valve, DOHC inline-four engine that provides top-shelf middleweight power, a trademark value of the Japanese bike builder. Squeezing big power from small displacement has always been a hallmark for the manufacturer and that tradition continues with the Ninja ZX-6R. The midrange power the bike has provides arm-stretching drive out of corners with the sort of precise throttle control that allows riders to enjoy the full, breath-taking experience of the Ninja ZX-6R. The bike’s engine is likewise mated to a cassette-type transmission that greatly simplifies gearing changes at the track, reducing set-up time and allowing more time for riding.
In terms of handling, the Ninja ZX-6R comes with its class-exclusive Big Piston front fork, a fully adjustable shock, ideal engine placement, optimum frame rigidity, and the very latest in mass centralization. Looking at the svelte profile of the bike, it’s easy to point out that the ZX-6R was designed with superior handling in mind. The bike’s twin spar aluminum frame is both lightweight and rigid, and places the engine in the optimum position for superb handling and rider feedback. Meanwhile, the bike’s sub-frame constitutes a two-piece aluminum die-casting consisting of a front and rear section while the lightweight sub-frame is very narrow, providing a compact and slim rear end that completes the overwhelmingly positive characteristics of the ZX-6R.

Camshafts are made of chrome-moly steel
Lightweight magnesium engine covers are standard
Lightweight top injector mounting plate
Lightweight transmission gears and gear dogs

Chassis and Suspension
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
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
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

Ultimate Motorcycling----"Kawasaki says: "Cylindrical guides in the top of the airbox guide the fuel charge into the intake funnels directly to reduce buffeting and improve cylinder filling. Advanced cylinder head porting slams the air/fuel charge into and out of the combustion chamber post-haste, while high-current secondaries in the ignition coils provide hot, consistent spark at all rpm for maximum combustion impact."
