1984
Suzuki Jaar code: E,
GSX-R400E, GSX400R-1
De GSX-R400 (aanvankelijk gewoon GSX-R genoemd in Japan,
interne modelcode GK71B) werd vrijgegeven in Maart 1984.
Het was de eerste in serie geproduceerde lichtgewicht
race replica met een alluminium spreid frame en een vloeistof-gekoelde
in lijn geplaatste vier cilinder motor, met vier kleppen
per cilinder. In die dagen werd de verbazingwekkende machine
gebaseerd op de Yoshimura TT-F3 racer nl. de GS1000R.
De concurerende Yamaha FZ400R en de Honda CBR400R waren
13-31kg (29-68 pond) zwaarder dan de nieuwe en zeer snelle
GSX-R.
In vergelijk tot de andere motorfietsen van die tijd,
was de GSX-R400 erg licht en de viercilinders tellende
voor-remklauwen en de twee cilinder achter-remklauwen
bleken wel heel erg adequaat te zijn voor een racer van
152kg (334 pond), zoals de GSX-R was. De motorfiets was
erg handelbaar en met erg sterke motor met 4-1 uitlaatsysteem
voor zijn grote, maakte dat de GSX-R zeker tot de snelste
uit zijn klasse gold. Met de maximum output van 59pk en
152kg (334 pond) droog gewicht, kracht/gewichts verhouding
(2,57kg/pk) was de GSX-R zelfs nog beter dan de 2-takt
RG250 racer van Suzuki. Met de GSX-R400 begon een nieuw
tijdperk en was het de snelste en handelbaarste 400cc
motorfiets die er ooit gemaakt was.
De met water gekoelde in lijn geplaatste vier-takt motoren
hadden een dubbele boven liggende nokkenas en vier kleppen
per cilinder. De GSX400FW die een jaar eerder werd gepresenteerd,
had de zelfde belangrijkste specificaties maar was veel
minder krachtig. Bovendien was de nieuwe motor van de
GSX-R met een gewicht van 66kg (145lbs) ruim 10kg (22lbs)
lichter.
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 toeren.

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 brake calipers, new fairing design with
faired-in headlights, preload-adjustable forks, unbraced
