1986 GSX-R750 - The birth of a legend
Suzuki's first GSX-R 750 made it's debut at the 1984 Cologne Motor Show, it made a splash then and continues to do so now. 

The lineage is long and proud.  The first GSX-R hit the market in March 1985 and the sportsbike world was never to be the same again. 

Light weight (only 179 kilograms dry and about 40 kilos less than any of the opposition) and good power from it's flat-slide equipped engine was a revolution for production motorcycles. An attractive full fairing design with endurance style twin headlights completed the picture and the early GSX-R remains an attractive machine even today.

1986 GSX-R750G
1986 saw the GSX-R get a 25mm longer swingarm and radial tyres. The headlights were upped in power. The big news was a new GSX-R750R limited edition model which featured a dry clutch, steering damper, larger brakes, solo seat and a host of suspension improvements.

1987 GSX-R750H
In 1987 the GSX-R became slightly more refined and the standard bike scored some of the previous models limited edition 'R' model goodies such as the stronger 41mm front forks and steering damper. 

The bike also now had the 310mm discs as standard fitment. Tyres and rims grew wider and a gold chain added to the bike's looks.

1988 GSX-R750J
A big change came in for the 1998 model year. Looks changed slightly to stay ahead of the times. 

The light aluminium frame got stronger and the forks were now up to 43mm in diameter.

Opposed 4-piston brake calipers aided things in the braking department. Engine cooling was improved by way of bigger oil cooler and redline now started at 13,000rpm. Bore and Stroke also changed from the previous 70x48.7mm to 73x44.7mm. 

New 'SlingShot' carbs were fitted in the aim of improving the responsiveness of the new shorter stroke engine. Air ducts were added to the front of the fairing to try and improve induction efficiency. 

1989 GSX-R750K and GSX-R750RK
The 1988 model took out both the manufacturers and riders World Endurance titles and the 1989 model aimed to capitalise on this success. 

Gear ratios were revised and another limited edition 'R' model was born. The GSX-R 750RK known as the double R was released in a limited run of 500 bikes. 

The engine reverted to the previous long stroke design and scored bigger 40mm carbs, close ratio gearbox and 4-into-1 exhaust. A fibreglass fairing, solo seat and 19-litre aluminium fuel tank helped achieve a 187 kilogram dry weight.

1990 GSX-R750L
Drawing from the now vast racing experience with the GSX-R Suzuki chose to give the standard GSX-R 750 some of the previous double R features. 

The long stroke engine again became standard with a new combustion chamber design, stronger con-rods and 38mm SlingShot carbs. Suspension became fully adjustable.

1991 GSX-R750M
1991 saw the GSX-R become more streamlined in the aim of reducing aerodynamic drag. A bigger seat improved comfort and a twin light rear end added to the new look. 

The Valve gear system was changed to a one rocker arm per valve system and the use of shims for valve adjustment was claimed to reduce internal friction by 5%. A new intake and exhaust port design aimed to increase high rpm power.
