It could reach a top speed of 268.2 km/h / 166.6 mph.  

==Engine==
The engine was a Liquid cooled cooled Four stroke, transverse four cylinder, DOHC, 4 valves per cylinder.. The engine featured a 11.5:1 [[compression ratio]].  

==Chassis==
It came with a 120/70 ZR17 front [[tire]] and a 190/50 ZR17 rear tire. Stopping was achieved via 2x 320mm discs 6 pistons calipers in the front and a Single 230mm disc 2 piston [[caliper]] in the rear. The front suspension was a  43mm inverted cartridge fork, adjustable preload, fully adjustable compression and rebound damping while the rear was equipped with a Piggy-back reservoir rear shock offers adjustable compression and rebound damping, preload and ride height to match a wide range of operating conditions.. The ZX-7R was fitted with a 18 Litres / 4.7 US gal fuel tank. The bike weighed just 203.4 kg / 456.3 lbs.

== Overview ==
Kawasaki ZX-7R
Ninja






















.Kawasaki's ZX-7R is a
perfect example of motorcycle engineering refinement. In 1993 Kawasaki
designed the new generation ZX-7R that has, to this day, remained virtually
unchanged. For 1997 Kawasaki continued to refine rather than redesign. It's
hard to argue against this approach as it is obviously working on the
racetrack. Doug Chandler's performance on the Muzzy Superbike is proof
enough that this machine is extremely competent.

The lack of obvious design changes or a new
appearance may make it hard for dealership salesmen to make their pitch, but
knowledgeable consumers will recognize the ZX-7R as an impeccable package
needing no sales hype.
The ZX-7R benefits from having any annoying
initial design flaws solved over its four years of steady refinement. This
makes for a pleasant ride with little to complain about. Some of the issues
Kawasaki addressed over the years were unusable mirrors and providing an
ergonomically correct cockpit.

One of the first things you'll notice when
riding the '97 ZX is that its mirrors are practical, allowing you a broader
view than just your shoulders. Its cockpit feels smaller and more compact than
on early models, with subtle comfort changes like adjustable levers to suit a
wide range of hand sizes that previously were unavailable.
"Pushing the ZX
hard in the canyons rewards the rider. Predictable steering is unmistakable
due to its 25 degrees of rake and 3.9 inches of trail."
Kawasaki's preference towards racers is evident
with the 1997 ZX-7R. Chandler and Muzzy seemed to have influenced the changes,
shaping it into a precision piece.
Its chassis is very well behaved, never doing
anything other than what's instructed.
Pushing the ZX hard in the canyons rewards the
rider. Predictable steering is unmistakable due to its 25 degrees of rake and
3.9 inches of trail.



The combination of larger than average trail
numbers and peculiarly narrow triple clamps require a heavy push on its
handlebars to turn the bike quickly, while the triangulated profile of the
Dunlop tires complements the bike's geometry perfectly, allowing it to reach
maximum lean angle quickly and effortlessly.
Although initial input is heavy, once leaned
over the handling is neutral and the profile effect of the tires is very
noticeable. Compared to early models, the new ZX-7 has better throttle
response and midrange acceleration. The main reason for these improvements is
the reduction of the intake ports by 4mm.
"Smaller ports
allow for better intake velocity and fuel atomization."
The increased velocity pulls a better signal at
the carburetor's needle jet, allowing for excellent carbonation.
Other improvements over the original formula
include Muzzy's touches in the form of strengthened crankshaft, two springs
per valve and a special baffle in the joint pipe to maximize exhaust pulse
effect for more torque. Low and mid torque was improved with a balance pipe
connected between the number one and number four header pipes. The head itself
was refined with straighter ports, aiming the 38mm carbs at 50 degrees into
the combustion chamber.
Kawasaki has now fitted the ZX's transmission
with involuted splines on the input and output shafts, allowing for less
backlash. Suspension components are also fully adjustable in the front and
rear and control the chassis' attitude well. Adjustments include compression,
rebound and ride height.


An experienced rider may now raise the rear to
reduce front rake for quicker steering, and its firm ride still will soak up
the big bumps. Those interested in commuting may choose to loosen the
suspension settings for more comfort around town. I would recommend adjusting
the factory settings by reducing front rebound two clicks, and dialing-in one
less click of rebound and 3mm less preload on the rear.
Brakes were improved for '97 by changing from
four-piston calipers to six-piston, with the result being increased feel and
power.
New brake pad material also contributes to
Grade-A stopping performance.
The initial bite isn't there, but a strong hand
increases stopping power with its rising rate. Improved from the original
1993-spec machine is the appearance and sound of its exhaust system. The sleek
looking pipe has a deep, powerful tone -- louder than most stock pipes.
Minimal restriction allows the engine to
breathe yet it still remains quieter than an aftermarket muffler.
"Among the most
noticeable changes in the new ZX-7R is the addition of another ram air duct in
the front fairing. Kawasaki's ram induction system is one of best designed. A
noticeable increase in acceleration is felt during top speed runs."

From a distance the 1997 ZX-7R doesn't look
different, but its refinements will be noticed in real world riding. It feels
small -- like a heavy 600cc bike, but with noticeably more low-end grunt and a
little more top end.
The power delivery is one of the most linear
I've ever sampled, and its spot-on carburetion, instant throttle response and
impeccable chassis manners make the ZX-7R a very logical buy.
