Overview
Suzuki GSX 550EF
GSX550EF is the middle class super sports brimming with
appeal.
The Rull Fairing
GSX550EF with SUZUKI'S 16-Valve DOHC Power Unit Really Knifes its Way Through
the Wind TSCC (Twin Swirl Combustion Chamber) Realizes High Power. High
Torque and Low Fuel Consumption. SUZUKI'S TSCC design extracts maximum
performance from its four-valve per cylinder engines. Two domes with their own
intake and exhaust valves are machined in the roof of the combustion chamber
for reduced mixture flow separation, generation of two swirls, enhanced mixing
when the mixture is jetted out from large squish areas at the end of the
compression stroke and more. The centrally located spark plug produces a
faster, more consistent bum and the head configuration promotes the smooth discharge. TSCC satisfies in the simplest way the
requirements for a high-performance engine: high power high torque and low
fuel consumption.
Posi Damp Fork:
SUZUKi's new Posi Damp Fork revolutionizes front fork design, combining superb
handling with a comfortable ride. A damping Control Unit switches compressing
damping force automatically between "soft" and "firm" according to fork
travel. A long stroke, caused by large bumps and high speed cornering, causes
fluid pressure to exceed the detection spring pre-set loading. A plunger is
forced upwards restricting the fluid passage and increasing damping force.
Four pre-sets for the detection spring enable the rider to choose the optimum setting for road
conditions. Regulated damping which matches ever-changing riding conditions.
Full Floater: Ideal Performance from Innovative Action,
SUZUKI's ingenious Full Floater rear suspension features a cushion unit which
floats" between a cushion lever and a swinging arm. Forces from the rear
wheel are transformed into rotational movement by the cushion lever depressing
the cushion unit, while the swinging arm exerts an upward thrust so that the
cushion unit is depressed from top and bottom at'the same time. The lever
ratio changes progressively to provide soft cushioning initially, becoming
gradually firmer as stroke and damper piston speed increases for the ideal
damping characteristics: soft at first, with a smooth, progressive transition
to firm.
Lightweight and Strong. SUZUKI'S Box Section Tubing Frame.
SUZUKI'S high-tensile steel box section tubing frame boasts light weight and
high resiliency. A further innovation is the clever combination of box section
members and round pipe members in the same frame The design incorporates a
wealth of data from computer stress analysis and SUZUKI knowhow gleaned from
the race track The result is a super light frame which has superb balance and
resiliency.
16 Inch Front Wheel. Straight from I Track Incredible
Handling. Bred for the race track, the 16 inch front wheel can now be
enjoyed on the road. It's light weight and low gyro force offers faster, more
responsive handling. The smaller circumference shortens braking distance for
the same effort. And its tire, caster angle and suspension stroke are all used
to their fullest advantage for fast and safe riding.
