The Kawasaki ZR550B Zephyr 550 was a in-line four, four-stroke Road motorcycle produced by Kawasaki in 1990. It could reach a top speed of 137 mph (220 km/h). Claimed horsepower was 48.95 HP (36.5 KW) @ 10000 RPM.
Overview
The Zephyr 550 was the smallest of the Zephyr range, and in some ways ahead of its time. Launched in 1991 as a stylish naked retro roadster, it occupied a niche later made very successful by Suzuki's Bandit. It used the air-cooled engine from the GPZ550, de-tuned for mid-range power, with minor cosmetic changes. The elderly engine was installed in a good-looking rolling chassis. A box-section aluminum twin-shock swingarm used sports-style eccentric chain adjusters, while a classically styled fuel tank and chrome-plated exhaust system rounded off the handsome design. The Zephyr's straight-line performance was disappointing though: the engine that produced 48kW (65bhp) in the GPZ550 was returned to make just 37kW (49bhp).
Engine
The engine was a oil & air cooled in-line four, four-stroke. A 58.0mm bore x 52.4mm stroke result in a displacement of just 553.0 cubic centimeters. Fuel was supplied via a double overhead cams/twin cam (dohc).
Drive
The bike has a 6-speed transmission. Power was moderated via the wet plate clutch.
Chassis
It came with a 110/80-17 front tire and a 140/70-18 rear tire. Stopping was achieved via 2x 300mm discs 2 piston calipers in the front and a Single 245mm disc 1 piston caliper in the rear. The front suspension was a 39mm Telescopic forks while the rear was equipped with a Dual Kayaba shocks with preload and rebound adjustments. The ZR550 Zephyr was fitted with a 15 Liters / 3.9 US gal fuel tank. The bike weighed just 179 kg / 394.6 lbs.
