1983 Suzuki year code: D

The GSX750ES, introduced in 1983 (called GSX750E in Japan), was based on the naked GSX750E.
Like its naked borther, the GSX750ES got the air and oil-cooled
16-valve engine with 84 hp (72 ps in Japan). The new GSX750 line
was the smallest, lightest and smoothest of Suzuki's 750cc machines
so far. Almost everything on the bike was new, including the cylinder
head and the frame.

The new 747cc engine shared only the cylinder measurements with
its precessor (63 mm bore, 53 mm stroke. It weigh 16,8 kg (37
lbs) less than the '82 GSX750 engine. Even the exhaust system
was made 5,3 kg (11,7 lbs) lighter. The new engine was even shorter,
narrower and lower than its precessor.

The maximum power output had increased from 81 to 86 hp by enlargening
the valves, increasing the compression ratio and re-designing
the cam shafts, exhaust system and the air filter box. Comparing
with modern engines, the GSX750ES engine don't impress with its
low-rev torque, but the older version of the engine had even less
torque.

The GSX750ES had a 16-inch front wheel (100/90-16) for quicker
steering and a 17-inch rear wheel (120/90-17). The craddle type
frame was welded using steel pipes and profiles and the light
alloy rear swing was an oil-damped Full-floater. An top fairing
was mounted on the ES model.

The GSX750ES proved to be a fantastic bike for its time. It was
sporty, fast and practical. It was easy to manouvre and good for
speeds over 200 kph. In many countries it was the best-selling
Suzuki in 1983. In Sweden it was actually the best selling bike
of the year, period.

An eight-page Japanese sales brochure can be found on the GSX750E brochures page.

1985 Suzuki year code: F

I must admit that I don't know if both the engine and the frame
(rear swing?) was upgraded for the 1985 year's model. According
to the Swedish specs the '85 models had longer wheelbase and more
powerful engine than the previous year's model.

1986 Suzuki year code: G

According to a frame code list from Suzuki, 1985 was the last
model year for the GSX750ES and GSX750EF but the models appeared
in the Suzuki lineup brochure in Sweden in 1986 (GSX750EF) and
in '87 (GSX750ES). According to a magazine
ad the GSX750EF had 90 hp in Sweden and the GSX750ES had 86
hp.

According to the picture I found on the Swedish Suzuki lineup
brochure from '86 (GSX750EF) it looks like the previous year's
model. I wonder how the 1986 GSX750EFG really looks like? Anyone?

1987 Suzuki year code: H

I don't know much of this model year. According to the picture
I found on the Swedish Suzuki lineup brochure from '87 (GSX750ES)
the seat looks different. 90 hp in Sweden.

The GSX750ES and EF models were replaced with the all new GSX750F
in 1988.
