Suzuki GSX-R750

The Suzuki GSX-R750 is a sports motorcycle made by Suzuki since 1984. It was introduced at the Cologne Motorcycle Show in October 1984 as a motorcycle of the GSX-R series for the 1985 model year.

The air and oil-cooled models can be divided into the first-generation and the second-generation colloquially referred to as 'slabbies' and 'slingshots' respectively. The 1985-1987 models featured very flat bodies compared to modern sport-bikes, hence the term 'slab-sided'. 1988-1991 (1992 USA) models are sometimes referred to as slingshots because the carburetors introduced in 1988 were marketed as slingshot carburetors (slingshot describes the cross-section of the semi-flat slide carbs).

The original model featured a lightweight aluminum alloy frame, flat slide Mikuni VM29SS carburettors, twin discs with 4-pot calipers, and 460-millimetre (18 in) tyres both front and rear. To save weight, the designers specified an air-and-oil-cooled engine, rather than a water-cooled engine. The seat has separate front and rear sections but from 1986 onwards all models have a one-piece seat.

The 1986 model received a 25 mm longer swing arm to improve the handling. Apart from a modified belly pan and upgraded headlamps, there is very little difference between the 1985 and 1986 models, other than the introduction of Mikuni CV carbs on some markets. 1986 is the first year the model was introduced to the US.

The Racing homologation Limited Edition model. 500 were manufactured worldwide, with 199 made for the US, 20 for Canada and 150 for the Japanese market. Its $6,499.99 retail price was 40% more expensive than the standard (G) model, making it the most expensive Japanese sport-bike money could buy that year. Unique items that differentiate this model from the standard (G) model include a dry clutch system, close-ratio 6 speed transmission, 29mm flat-slide carbs, 19L steel gas tank, hand-laid fiberglass solo rear section with single racing seat, side bodywork utilizing Dzus quick release fasteners and Limited-Edition graphics.

The distinctive clutch and actuator housing along with the sprocket cover are all made of magnesium for reduced weight. The clutch actuation is uniquely cable operated rather than hydraulic, offering greater feel and lighter weight. Suspension features the 1986 GSX-R1100's electronically controlled 41mm NEAS anti-dive forks, rims, brake calipers & larger 310mm floating discs, specially designed front brake hoses, a unique "3 point" steering damper and broader clip on handlebars. Out back, a 1" longer swingarm is fitted with threaded inserts for a racing style paddock stand, and an aluminium-bodied shock absorber with remote gas-charged reservoir. Other features found only on this model include a gold plated chain, uniquely patterned exhaust heat shield, premium aluminum exhaust hanger, heal guards, chain guard, bar-end weights, adjustable clutch lever, a visually machined top triple clamp and changes to the bodywork to improve cooling. To seal the deal, included with the purchase were 2 complete sets of racing numbers.

There were two variants of the 1986 GSXR750 Limited Edition. One version was released in the US, Europe and Canada and another was for the Japanese market. The Japanese version had red and gray graphics, along with a fuel gauge, headlight kill switch, tinted turn signal lenses, Japanese-spec city lights, and a black four-into-one "Ray Gun" exhaust system. The non Japanese variant came in a red, white and blue livery, did not have the Japan only items and sported an exhaust pipe with an aluminum heat shield.

The 1987 model received upgraded 41 millimeter front forks with NEAS (New Electrically Activated Suspension) from the previous year's RR and a steering damper was fitted as standard (note this was only the Japanese model, everyone else got the same forks/brakes as the 85/86 ). The fuel tank capacity was increased to 21 liters.
