Z750S Streetbike

The new-for-2005 Kawasaki Z750S motorcycle offers a unique combination of NINJA® sportbike performance, comfort for two-up touring and the aggressive style of Kawasaki’s “super naked” Z1000.

Initially launched in Europe and refined for American riding styles, the new Z750S is powered by a liquid-cooled, 748cc, inline four-cylinder engine that delivers a smooth linear powerband. It features a bore and stroke of 68.4mm x 50.9mm, double overhead cams, 16 valves, reshaped intake ports, exhaust ports and combustion chambers. A four-into-one exhaust system enhances mid-range power, while an oval-shaped, racing-inspired muffler helps to keep the Z750S running quietly. The muffler also includes a metal honeycomb catalyzer to reduce emissions.

The Z750S is the first middleweight naked bike to feature electronic fuel injection and utilizes 34mm throttle bodies. Combined with high-speed digital ignition, both systems are managed by an electronic engine control unit for snappy throttle response.

To maintain a consistent operating temperature, the Z750S utilizes the same large radiator and ring fan as that found on the Z1000.

Power is transferred to the rear wheel through a six-speed transmission and 520 X-ring drive chain, and the Z750S rides on high-performance radial tires mounted on new six-spoke 17-inch wheels. The new wheels do more than look good – they are lighter and stronger than previous three-spoke designs, further reducing the bike’s overall dry weight.

The lightweight diamond frame for the Z750S is constructed of large diameter, thin wall tubing for strength and rigidity for nimble backroad handling and high-speed stability. Plus, the detachable right front-top portion of the frame makes tune-ups easier.

Performance-tuned 41mm forks, plus a rear swingarm featuring cast aluminum UNI-TRAK® linkage and shock with four-way rebound damping and seven-way spring preload adjustments help the Z750S soak up road bumps. Dual 300mm front disc brakes with four-piston calipers and a 220mm rear disc brake help the rider bring the Z750S to quick, powerful stops.

Being a naked bike doesn’t mean the Z750S is without amenities. The half-cowl on the Z750S gives it a lean, provocative look, while quartz halogen headlights brighten the road at night. The instrument panel – shared with the NINJA ZX-10R – glows with a new, bright red backlight for a high-class look and includes a radial tachometer and speedometer, odometer, tripmeter, fuel gauge and clock, while the modern LED taillight and turn signals are shared with the new NINJA ZX-6RR.

The swingarm-mounted inner fender and front fender contribute to the aggressive, sporty image of the Z750S. The galvanized steel fuel tank is slender and helps to create a seating position that is comfortable and allows the rider to mold to the bike. The new tandem seat features sleek passenger grab bars and an optional tandem seat cover is available from Kawasaki.
