Suzuki the 1980's

In 1980 Suzuki produced the GSX750E with a Twin Swirl Combustion Chamber (TSCC) and 4 valve DOHC.

In 1981 the Katana rolled off the line, The GSX1100s, it boasted a power output of 111ps at 8,500rpm - 6ps more than the GSX1100E

In 1985 Suzuki wentr a step beyond, with the introduction of the XN85. The first production Turbo Motocycle. The XN85 was based on the GS650G, the number 85 denoted the 85pse showing the bike was more than just a turbo added to a 650. The bike also included an electronic fuel injector, remote preload adjustment mechanism for the rear suspension and oil-jet forcible cooling system that sprayed oil on the back of the piston.

In 1982 Suzuki redesigned the RM250. The liquid-cooled 2-stroke 246cc single-cylinder delivered 43ps which was the highest among the competitive production machines of the time. It featured Suzuki’s original full floater, link-type rear suspension

In 1983 Suzuki produced the RG250Γ. RG-Γ machines dominated the WGP (World championship Grand Prix) series in the early 1980s. In keeping with that spirit, Suzuki released the RG250Γ. This machine saw the adoption of the AL-BOX, square aluminum frame, 16-inch tire and Anti Nose Dive Forks (ANDF) at the front. With an output power of 45ps at 8,500rpm, the engine made the RG250Γ the most powerful machine in its class. Lavishly equipped with technology developed for the racetrack, the RG250Γ was the first ever full-blown racer replica.

That same year Suzuki started production of it's Quads, the first being the 125 Quad Runner. Since this is post is dealing with motorcycles I will only show this one quad although Suzuki has continually redesigned these Motorsport units as well.

1985 was a busy year for the Company, producing the Concept model Falcorus Tyco at the  Tokyo Motor Show, the RG500Γ, the GSX-R750, the V-Twin Intruder 750, and racer Quad line.

RG500Γ naturally featured the same square 4-cylinder engine and displacement as the RG racing machines, the same bore x stroke and center distance. The crankcase was also based on the RG design, and each machine was equipped with a removable cassette-type transmission.

The GSX-R750 weighed in at a mere 179kg. Mounted on an aluminum double-cradle frame dubbed the MR-ALBOX, the 4-cylinder DOHC engine used the Suzuki Advanced Cooling System (SACS), cooled by forcibly pumping in oil. With tuning by companies such as Yoshimura, the GSX-R750 turned in spectacular performances at both domestic and overseas circuits.

The Intruder 750's unique OHC 4-valve 45° V-shape engine was mounted on a classical frame. The Intruder 750 was renowned for its lavish construction, typified by the cylinder-cooling fan, despite the fact that the engine was entirely liquid-cooled, it was expressly designed to appeal to the US consumersT

The 1986 GSX-R1100, was a monster machine that recorded a top speed of 265km/h - the highest speed of any stock motorcycle in the world at the time. Equipped with the unique oil-cooling Suzuki Advanced Cooling System (SACS), the engine generated astoundingly high power output of 130ps. The combination of the power and lightness, it was dubbed a "super lightweight", led it to be acclaimed as a racing machine that could run on the public road. With a power-to-weight ratio of 1.5kg/ps, the GSX-R1100 could cover 1/4 mile in 10.3 seconds.

In 1987 Suzuki again stepped forward with the concept motorcycle "NUDA". It featured an ultra-advanced mechanism of "fulltime 2-wheel drive" developed with the accumulated ideas of Suzuki engineering staff. The technologies for creating an excellent drivability were also incorporated boldly in the power steering and swing seat. And high rigidity and weight reduction were realized by the adoption of honeycomb mono-cock body made of carbon fiber.

Suzuki rounded out the 80's with the 1988 introduction of the "RGV250Γ/SP". With the change from 2-cylinder in-line engine to 90° V-shaped 2-cylinder engine, the RGV250Γ acquired the "V" in its name. The RGV250Γ SP was released to commemorate Kevin Schwantz's victory in the Japanese Grand Prix.
