The Kawasaki ZRX1200R, a standard/naked motorcycle, was manufactured in Japan by Kawasaki from 2001 until 2008. It is an evolution of the ZRX 1100, a stylized replica of the "Eddie Lawson Replica", a motorcycle made famous by the superbike racing champion of the same name.[1] With the ZRX1200R, Kawasaki's goal was to produce a motorcycle with the performance of a modern motorcycle, while retaining a design similar to the original Eddie Lawson Replica. Worldwide, the ZRX 1200 was available in three guises: the ZRX1200S, which was partially faired; the ZRX1200R, which had a bikini fairing; and the ZRX1200N, which had no fairing. Unlike sport bikes, full handlebars made of tubular aluminum are utilized. For comfort, the saddle contains more than one centimeter of padding between the seat covering and the pan. Foot pegs are positioned similar to standard motorcycles, creating a seating position reminiscent of the classic Universal Japanese Motorcycle (UJM). The frame is conventional steel tube with the engine supported in a removable cradle. The suspension configuration is similar to that found on a UJM. The lay-down rear shocks, designed with a built-in remote reservoir, are adjustable for preload and damping. The front suspension consists of conventional forks with adjustable damping and preload. The reinforced swing arm was designed to mimic the modified/aftermarket swingarms produced in the 1970s. The bike features a liquid-cooled 1164cc inline 4-cylinder engine. Induction comes through four 36mm Keihin Constant Velocity carburetors. The exhaust system is a 4-into-1 stainless steel unit. The exhaust system on models produced up to 2004 are painted black, with the exception of the muffler, models produced from 2004-onwards are equipped with polished exhaust systems.


Engine[edit | edit source]

The engine was a Liquid cooled cooled Four stroke, transverse four cylinder, DOHC, 4 valves per cylinder.. The engine featured a 10.1:1 compression ratio.

Chassis[edit | edit source]

It came with a 120/70 ZR17 front tire and a 180/55 ZR17 rear tire. Stopping was achieved via 2x 310mm discs 6 piston calipers in the front and a Single 250mm disc 2 piston caliper in the rear. The front suspension was a 43 mm fully adjustable, conventional cartridge-type fork, offers 12-way compression and rebound damping adjustment as well as fork spring preload while the rear was equipped with a Fully adjustable rear shock. The ZR-X 1200R was fitted with a 19 Liters / 5.0 US gal fuel tank. The bike weighed just 223 kg / 491.6 lbs. The wheelbase was 1465 mm / 57.7 in long.

Overview[edit | edit source]

Introduced in 2001 as a replacement for the ZRX1100, the ZRX1200R is much more of an update than it looks. Externally similar to the 1100, the ZRX1200R had a host of engine changes, all aimed at modernizing the design and improving power delivery. The 112cc capacity increase to l,164cc was made possible by replacing the old engine's steel cylinder liners with a plated aluminum block, but the altered block meant new crankcases. The chassis was less radically altered. A stiffer swingarm and revised shock positioning, with slightly longer wheelbase, improved stability. The neat headlight fairing was retained on this ZRX1200R model, and instruments and controls were similar. Kawasaki also produced an unfaired ZRX1200.


The Kawasaki ZRX1200 musclebike delivers the style and character of early-1980s factory Superbikes, but with modern-day performance. With its distinctive paint schemes, bridged-aluminum alloy swingarm and four-into-one exhaust, the hugely popular, well-acclaimed ZRX1200R calls to mind the KZ1100 Eddie Lawson Replica from Kawasaki's early racing years.

The ZRX1200R's torque-happy engine is based on the mighty Kawasaki NINJA® ZX-11 powerplant. Horsepower distinguishes the ZRX1200R from the rest of the unfaired pack, and its engine is tuned with emphasis on low and midrange rpm performance. This allows for abundant torque, and in turn, the bike's user-friendly personality on the street and amazing roll-on performance on the highway.

The ZRX1200R engine features electroplated cylinders, which transfer heat much quicker than steel so tighter tolerances can be utilized to generate more power. Pistons with concave domes are found in the lightweight, all-aluminum cylinder block.

Adding to the ZRX1200R's incredible torque is the bank of large-bore 36mm Keihin carburetors featuring the Kawasaki Throttle Responsive Ignition Control (K-TRIC) throttle position sensor. Connected to the digital ignition system, K-TRIC 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.

Engine vibration is reduced, especially in the 2,000-rpm range, due to a diaphragm spring that has been 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 made entirely of stainless steel with a polished muffler. California models have a catalyzer in the exhaust system to reduce emissions without cutting power.


The engine rests in a tubular-steel, double-cradle frame with an additional gusset behind the steering head for greater rigidity. The swingarm pivot is located for excellent rear suspension action and traction from the wide rear-wheel, 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® ZX-12R sportbike. 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.

The ZRX features a comfortable, upright riding position. Hollow footpegs and rubber-mounted handlebars reduce vibration, while aluminum grab rails are located on both sides of the seat. The 5.3-gallon fuel tank is specially designed so that a tank bag can be easily installed.

Like its award-winning predecessor, the ZRX1200 snagged "Best Standard" in Cycle World magazine's Ten Best list for 2001 and is a finalist for Motorcyclist magazine's "Bike of the Year" for 2001, among other accolades. It's no surprise, then, that the ZRX1200R carries on Kawasaki's legendary performance heritage in the Open class.
