The bike is characterized by being the only modern road sports bike to have an in-line four-cylinder engine with a 399 cm3 displacement, therefore an engine with a very small volume but with a multicylinder fractionation. [4] The engine is mounted in front of the gear and is powered by a multipoint indirect electronic injection system having 4 injectors with 16-valve DOHC distribution, four for each cylinder; it delivers about 57 kW (77 HP), 42 Nm of torque and can reach 15,000 rpm. The power can be increased to 80 HP with the aid of an Air box. [5] [6]

There are three versions available: the base ZX-4R, the ZX-4R SE and the top of the range ZX-4 RR. The Special Edition is characterized by the colors and graphics inspired by the bikes of the official Kawasaki stable that races in the SBK championship and offers as standard the Quick Shifter, the Smoked windshield, the USB socket and the frame protections. The RR differs in the oversized rear shock absorber.

The chassis, partially derived from that of the smaller ZX-25R, has been redesigned and features a diamond-shaped high-strength steel trellis structure supported by a curved rear swingarm. The steering head angle is 23.5°. The weight varies depending on the trim level, from 188 kg for the base and RR to 189 kg for the SE. [7]

At the front, the upside-down telescopic fork is a Showa SFF-BP (the ZX-4SE and ZX-4RR also have a preload adjustment mechanism), while at the rear there is a horizontal back-link suspension partially derived from the larger ZX-10R; the ZX-4RR variant has the same Showa BFRC-lite rear shock as the Ninja ZX-10R. The braking system at the front consists of twin 290 mm semi-floating discs and monobloc radial calipers, while at the rear it uses a single 220 mm disc. The 17-inch alloy wheels are fitted with 120/70 front tires and 160/60 rear tires respectively. [5]

<span class="mw-page-title-main">Kawasaki Ninja ZX-12R</span> Type of motorcycle

The Kawasaki Ninja ZX-12R is a motorcycle in the Ninja sport bike series made by Kawasaki from 2000 through 2006. The 1,199 cc (73.2 cu in) inline-four engine produced 178 hp (133 kW) at low speed, and increased to 190 hp (140 kW) at high speed due to its ram-air intake, making it the most powerful production motorcycle up to 2006 and the release of the ZX-14. It was a contender to be the fastest production motorcycle, and played a role in bringing to a truce the escalating competition to build an ever-faster motorcycle. Its top speed was electronically limited to 186 mph (300 km/h), tying it with the Suzuki Hayabusa and Kawasaki Ninja ZX-14 as the fastest production motorcycle on the market, after the 303–312 km/h (188–194 mph) 1999 Hayabusa was replaced with a speed-limited version as part of a gentlemen's agreement between motorcycle manufacturers that lasted until the 298–311 km/h (185.4–193.24 mph) 2007 MV Agusta F4 R 312.
