1984 Suzuki
year code: E,
GSX-R400E, GSX400R-1
The GSX-R400 (initially called GSX-R in Japan, internal model
code GK71B) was released in March 1984. It was the first mass-produced
light-weight racer replica with an aluminum cradle frame and a
liquid-cooled inline-four DOHC engine with four valves per cylinder.
The, in those days, amazing machine was based on Yoshimura's TT-F3
racer GS1000R. The competitors, Yamaha FZ400R and Honda CBR400R
were 13—31 kg (29—68 lbs) heavier than the new and
quick GSX-R.
Compared
to other bikes of the time, the GSX-R400 was very light and the
4-piston brakes at the front and the 2-piston rear brake was more
than adequate for the 152 kg (334 lbs) light street racer. The
bike was quick to handle, the engine with 4-1 exhaust system was
powerful for its size and made the GSX-R the fastest bike in its
class. With the maximum power output 59 hp and 152 kg (334 lbs(
dry mass, the power/weight ratio (2,57 kg/hp) was even better
than Suzuki's incredible 2-stroke racer, RG250 Gamma. The GSX-R400
started a new era, it was the fastest and best-handling 400cc
bike ever made.
The
water-cooled inline-four four-stroke had double overhead camshafts
and four valves per cylinder. The GSX400FW (presented the previous
year) had the same principal engine specs but lower power output
and the GSX-R400's new engine with its 66 kg (145 lbs) was 10
kg (22 lbs) lighter. 12,000 maximum revs.

1985 Suzuki year code:
F, GSX-R400F,
GSX400R-2
The GSX-R400F (GSX-R Type 2) was released in March 1985. The maximum
power and torque of the engine remained the same but the power
output was improved at the middle-range revs by changing the carburetor
settings. A simple fuel meter was added to the model, the remaining
amount of fuel was indicated by the right side combination meter
when the power switched in OFF position. Some improvements were
made to the electric system.
1985
was the year the famous GSX-R750 was launched and caused a sensation
with its appearance, power and light weight. The 750 cc version
had even better power/weight ratio than its little brother and
was much faster but not that different from the original, GSX-R400.
It was fairly unknown in the time in the Western world but the
GSX-R750 became instantly known as the sensational new racer replica
from Japan. The fact that the GSX-R400 was released a year earlier
is still unknown to many motorcycle enthusiasts outside Japan.

The power/weight ratio was a bit better in 1986 0,39 hp/kg (0,18
hp/lbs). The upgraded GSX-R400 new chassis, shorter wheelbase
and was totally redesigned. I fact, you could say it was a totally
new bike. It even got a new internal model code: GK71F (presented
in March 1986).
The
1986 and 1987 year's engines differ from the other models, they
do not have the normal type of liquid-cooled engines. Instead
they the use the SATCS (Suzuki Advanced Three-way Cooling System)
that used water, oil and air to keep the engine from overheating.
The
1986 year's GSX-R400 (Type 3) had a single square headlight instead
of two round headlights. The new front design didn't gain popularity
and the twin headlight were reintroduced the following year.

1987 GSX-R400 was practically the same bike as the previous year's
model. The bigger differences were new wheels, twin headlight,
Gold brake calipers, paint scheme and different design of the
exhaust pipe. A Special Edition was available with black/gold
color scheme.
According
to the Swedish Suzuki importer the GSX-R400 was distributed only
in Japan and Sweden. For the first the model was called GSX-R400
in Japan, all the earlier models were called called ”GSX-R”
without the ”400” ending.

1988 Suzuki year code:
J, GSX-R400J

The GSX-R400 got a new frame (GK73A) and new overall appearance
in 1988. The new model was presented in February 1988. The redesigned
GSX-R got once again new fairing and shorter wheelbase, but the
weight increased a bit due to the stronger new chassis and exhaust
system. The model also got slingshot carburetors, polished chrome
silencers, curved radiator, Tokico 4-cylinder front brake calipers
and a rear hugger mudguard.
The
new 4 into 2 exhaust was meant to increase the torque on the mid-range
band, but had only a marginal effect.
The
400cc series were increasing popularity in Japan and a production
racer with different suspension and gearing, GSX-R400 SP (Sports
Production) was presented for 1988. It looked almost identical
with the standard GSX-R400 but didn't have passenger foot pegs
and you could spot the rear suspension gas reservoir peeking out
from under the seat. Also the front suspension was different from
the standard model. The SP version also had a Sports Production
logo on the tailpiece.
To
compete in production racing, the manufacturers produce SP (Sports
Production) versions of their sports bikes. These usually have
fully adjustable suspension, close ratio gearboxes and a single
seat but didn't have more power, due to Japanese motorcycle manufacturer's
power restriction code.
The
SP's are claimed to be even harder work on the road than a standard
GSX-R400. Not that surprising knowing that it was designed for
racing only.
Available
colors: Blue/White, Black/Red/White, Black
The SP model was available in Blue/White only.

The frame was upgraded from twin spur to double cradle, similar
to the 1988 GSX-R750 model change.
A
new 4 into 1 exhaust increased the engine power close to 60bhp
and the engine redlined at 14,500 rpm. Nissin 4-cylinder front

Redesigned brake discs and new painting, otherwise pretty much
