- 2005 Kawasaki ZRX1200R
As the muscle car of the motorcycle world, the Kawasaki
ZRX1200 has the good looks of yester-years Japanese standards. Combined
with a relatively upright seating position, the torque of a big-bore engine
and sturdy chassis, just looking at its inviting contours makes even the most
casual observer want to ride.
In addition to its unique styling, horsepower separates the ZRX1200R from other standards, thanks to an engine tuned with emphasis on low- and mid-range rpm performance. The ZRX1200R engine features electroplated cylinders, which transfer heat much quicker than steel, allowing tighter tolerances to be utilized to generate more power. Pistons with concave domes are found in the lightweight, all-aluminum cylinder block. This translates to a user-friendly street personality and amazing roll-on performance on the highway.
Building on the ZRX1200Rs already incredible torque is the bank of large-bore 36mm Keihin carburetors featuring the Kawasaki Throttle Responsive Ignition Control (K-TRIC) throttle position sensor. K-TRIC is connected to the digital ignition system and varies ignition timing according to throttle position and engine rpm so that the ignition compensates for differing engine loads. The result is crisp throttle response and better fuel efficiency, plus the carburetors have coasting enricheners to prevent backfiring.
With so much power on tap, engine vibration had to be reduced, especially in the 2,000-rpm range. Kawasaki accomplished this by designing a diaphragm spring that is placed between the primary gear and clutch housing. The spring not only provides smooth low-rpm operation, it also works with the shift drum and cam profile to help improve shifting of the five-speed transmission.
The four-into-one exhaust system is constructed entirely of stainless steel with a polished muffler. California models have a catalyzer in the exhaust system to reduce emissions without cutting power.
The ZRX1200Rs engine rests in a tubular-steel, double-cradle frame with an additional gusset behind the steering head for greater rigidity. The swingarm pivot is positioned for excellent rear suspension action and to reduce chain-torque reaction. The swingarm features an underside-braced design, and is shaped for increased rigidity.
Driveline lash is reduced with the use of a urethane rear-wheel damper borrowed from the NINJA® sportbike design. Exceptional braking is provided by the dual 310mm front discs with opposed six-piston calipers, while the rear brake uses a single 250mm disc clamped by an opposed twin-piston caliper. Hollow three-spoke wheels grace both ends.
For rider comfort, the ZRX1200 features an upright riding position, while hollow footpegs and rubber-mounted handlebars reduce vibration and make the ride even more enjoyable. Aluminum grab rails are located on both sides of the seat to accommodate a passenger, and the 5.3-gallon fuel tank is specially designed so that a tank bag can be easily installed.
Features and Benefits
Four-Cylinder, 16-Valve Engine
- Aluminum cylinders are electroplated for quick heat transfer, allowing closer tolerances for more power
- Compact combustion chamber for increased compression ratio without detonation on todays gasolines
- 16-valve design boosts low-end torque and provides maximum valve area for optimum flow
Gear-Driven Engine Balancer
- Smoothes engine vibration for comfort on the road
- Maintains consistent engine temperatures for long engine life and sustained power during hard use
- Automatic fan keeps things cool even in traffic
36mm Carburetors with Kawasaki Throttle Responsive Ignition Control (K-TRIC)
- A throttle-position sensor tells the ignition-control unit how hard the engine is working so that its micro-computer can determine the best ignition timing for more power and better fuel economy
- Microprocessor controlled timing, never needs adjustment
Large-Capacity Fuel Tank
- 5.3-gallon capacity for extended rides without refueling
Bridged Aluminum Swingarm
- Rectangular design is large and stiff
- Eccentric chain adjusters
43mm Cartridge-Type Front Fork
