KAWASAKI
GPZ 500S - 1991
An excellent medium twin
Kawasaki not only builds the
famed big "Kwackers" but also offers a full range of models for
various purposes, each with its own character. The GPZ 500S is an economical
high-performance, medium-capacity machine that is also extremely rational.
Half an RX 1000 Four
Launched in 1987, the GPZ 500S
is one of the rare modern Japanese bikes to use a four-stroke vertical-twin
power plant. The choice was dictated by considerations of marketing – for its
uncomplicated image – and cost-cutting, because the GPZ twin uses many of the
internal components of the RX 1000cc four. This modern 60 hp twin offers
extremely competitive levels of performance as well as over 36 lb-ft of torque.
Besides, its compactness has enabled the designers to create a low, narrow
machine weighing just 440 lb ready to roll.
Ideal for the Tyro
The chunky GPZ 500S is an
ideal bike for the relatively inexperienced beginner. Mounting it is no great
problem. The low saddle height, the excellent weight distribution and the good
handling at low speeds make the GPZ 500S an excellent bike for city streets,
despite its engine's lack of flexibility under 3000 rpm. Above that level, it
really comes to life. Thanks to its performance and comfort, this Kawasaki is
well-suited to touring, for its well-sorted frame and powerful braking give a
sporty ride on twisting roads. The economical GPZ 500S is an excellent example
of the modern all-purpose medium capacity motorcycle.
