subject: The History Of Suzuki Gsx-r750 Motorcycle [print this page] The GSX-R750 is a 750 class sport bike motorcycle from Suzuki's GSX-R series of motorcycles. It was introduced in 1985 and can be considered to be the first of the modern racer-replicas with many race-derived technologies and the looks of a Suzuki Endurance racer at an affordable price.The oil-cooled models can be further divided into the first generation and second generation oil-cooled models. They are informally referred to as slabbies (slang) and slingshots respectively. The 85-87 models featured body work which is very flat compared to modern sport-bikes, hence slab-side. The '88-91 (92 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, flatslide carbs, twin discs with 4-pot calipers and 460-millimetre tires both front and rear. The unusual choice of an oil-cooled engine was made to save weight as compared with the heavier water-cooled engines of the time. The 1986 received a 25 mm longer swing arm to help calm the handling. Apart from a modified belly pan and upgraded headlamps there is very little difference between the 1985 and 1986 models. This is the first year the model was introduced to the USA. Racing homologation Limited Edition model, limited production. Including a dry clutch system, alloy tank, solo seat rear section bodywork and Limited Edition graphics. The 1987 model received upgraded 41 mm front forks with NEAS from the previous year's RR and a steering damper was fitted as standard. A larger 21 liter fuel tank was added. First major revision. New chassis design, engine revisions and body work. Introduction of a new short-stroke version of the oil-cooled engine, now displacing 748 cc. Engine had 73 mm bore and 44.7 mm stoke and could achieve higher engine speeds. Internal engine dimensions changed to accommodate the new bore and stroke. Minor changes such as: modified lower bodywork, changes to graphics and silver exhaust silencers. Magazines reported that the exhaust manifold now featured small chamfers on the collector for increased ground clearance. Limited edition racing homologation model. The redesigned engine reverted to the original long stroke configuration.
Although this model looks very similar to the previous '89 model many changes were made. The 90 model featured changes to the engine, suspension, body work, brakes and chassis. This was the first GSX-R to be fitted with inverted forks as standard (USA models retained the conventional forks until 1991), and returned to the bore and stroke dimension of the original long-stroke engine.The engine returned to the 749 cc engine bore and stroke dimensions of the original long-stroke engine but still maintained the 13,000 rpm redline. It now featured mm valve and used larger carburetors. The new Mikuni model BST38SS carburetors were 38 mm diameter and featured an additional high-speed circuit and the slide breathers were now divorced from air box. The exhaust system was also changed, gone were the dual silencers and replaced with one stainless steel silencer on the right side. The transmission output shaft was lengthened to accommodate a wider wheel. A new curved oil-cooler design and oil lines were installed.For more infor about Honda Motorcycle Fairings, Carnages CBR, Please visit our website!
