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).

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 retuned to make just 37kW (49bhp).
