”A machine that inherits the blood of the durable racer GS1000R.” The Suzuki GSX-R was equipped with dual headlamps, cowling, etc. with the same styling as the GS1000R (in the backgorund), the champion machine of the 1983 World Championship endurance race.

1984 Suzuki year code: E, GSX-R400E, GSX400R-1

Suzuki's groundbreaking new model, the GSX-R400 (initially called GSX-R in Japan, internal model code GK71B) was released in March 1984. It was the first mass-produced light-weight racer replica with an aluminum cradle frame and a liquid-cooled inline-four DOHC engine with four valves per cylinder. The, in those days, amazing machine was based on Yoshimura's TT-F3 racer GS1000R. The competitors, Yamaha FZ400R and Honda CBR400R were 13—31 kg (29—68 lbs) heavier than the new and quick GSX-R. Compared to other bikes of the time, the GSX-R400 was very light and the 4-piston brakes at the front and the 2-piston rear brake was more than adequate for the 152 kg (334 lbs) light street racer. The bike was quick to handle, the engine with 4-1 exhaust system was powerful for its size and made the GSX-R the fastest bike in its class. With the maximum power output 59 hp and 152 kg (334 lbs( dry mass, the power/weight ratio (2,57 kg/hp) was even better than Suzuki's incredible 2-stroke racer, RG250 Gamma. The GSX-R400 started a new era, it was the fastest and best-handling 400cc bike ever made. The water-cooled inline-four four-stroke had double overhead camshafts and four valves per cylinder. The GSX400FW (presented the previous year) had the same principal engine specs but lower power output and the GSX-R400's new engine with its 66 kg (145 lbs) was 10 kg (22 lbs) lighter. 12 000 maximum revs. The GSX-R was equipped with dual headlamps, cowling, etc. with the same styling as the GS1000R, the champion machine of the 1983 World Championship endurance race.

1985 Suzuki year code: F, GSX-R400F, GSX400R-2

The GSX-R400F (GSX-R Type 2) was released in March 1985. The maximum power and torque of the engine remained the same but the power output was improved at the middle-range revs by changing the carburetor settings. A simple fuel meter was added to the model, the remaining amount of fuel was indicated by the right side combination meter when the power switched in OFF position. Some improvements were made to the electric system. 1985 was the year the famous GSX-R750 was launched and caused a sensation with its appearance, power and light weight. The 750 cc version had even better power/weight ratio than its little brother and was much faster but not that different from the original, GSX-R400. It was fairly unknown in the time in the Western world but the GSX-R750 became instantly known as the sensational new racer replica from Japan. The fact that the GSX-R400 was released a year earlier is still unknown to many motorcycle enthusiasts outside Japan. Starting frame number: GK71B-114715

Updated model. The power/weight ratio was a bit better in 1986 0,39 hp @ kg (0,18 hp @ lbs). The upgraded GSX-R400 new chassis, shorter wheelbase and was totally redesigned. I fact, you could say it was a totally new bike. It even got a new internal model code: GK71F (presented in March 1986). The 1986 and 1987 year's engines differ from the other models, they do not have the normal type of liquid-cooled engines. Instead they the use the SATCS (Suzuki Advanced Three-way Cooling System) that used water, oil and air to keep the engine from overheating. The cylinder head is water-cooled, the cylinder block is air-cooled by fins, and the inside of the piston is oil-cooled to improve cooling efficiency and make the engine more compact. The 1986 year's GSX-R400 (Type 3) had a single square headlight instead of two round headlights. The new front design didn't gain popularity and the twin headlight were re-introduced the following year. Retail price in Japan 1986: 66 900 Yen

1988 Suzuki year code: J, GSX-R400J

The GSX-R400 got a new frame (GK73A) and new overall appearance in 1988. The new model was presented in February 1988. The redesigned GSX-R got once again new fairing and shorter wheelbase, but the weight increased a bit due to the stronger new chassis and exhaust system. The model also got slingshot carburetors, polished chrome silencers, curved radiator, Tokico 4-cylinder front brake calipers and a rear hugger mudguard. The new 4 into 2 exhaust was meant to increase the torque on the mid-range band, but had only a marginal effect. The 400cc series were increasing popularity in Japan and a production racer with different suspension and gearing, GSX-R400 SP (Sports Production) was presented for 1988. It looked almost identical with the standard GSX-R400 but didn't have passenger foot pegs and you could spot the rear suspension gas reservoir peeking out from under the seat. Also the front suspension was different from the standard model. The SP version also had a Sports Production logo on the tailpiece. To compete in production racing, the manufacturers produce SP (Sports Production) versions of their sports bikes. These usually have fully adjustable suspension, close ratio gearboxes and a single seat but didn't have more power, due to Japanese motorcycle manufacturer's power restriction code. The SP's are claimed to be even harder work on the road than a standard GSX-R400. Not that surprising knowing that it was designed for racing only. Available colors: Blue/White, Black/Red/White, Black The SP model was available in Blue/White only.

In 1989 an extra ”R” was added to the model name. The new model name was GSX-R400R although the internal model code (frame code) remained the same. A Production Racer version, GSX-R400R SP, was released in June 1989 with close ratio gear box, uprated suspension and different CDI. There's no second pair or foot-pegs or rear seat for a passenger on the SP.
