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). | |||
