Suzuki GSX750ES and GSX750EF
1983—1987

I have tried to tell the SuzukiGSX 750 ES and GSX 750 EF model histories on this page, as I know it. The page is still under construction. I would be grateful of any contributions — sales brochures, magazine ads, magazine articles, pictures, specs, facts, corrections etc. Please scan the material in JPEG format (large enough that all the details are visible) and send them to me. Please tell me the source and the publication date if possible. If you send me pictures of your own bike, please follow these instructions.

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.

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?

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.
