Suzuki GSX-R series Motorcycle images and photos – cool suzuki motorbike wallpapers

In 1984, Suzuki released the first GSX-R (GSX-R400, internal model number GK71b), on sale only in Japan, taking advantage of licensing laws there which were prohibitive of bikes over 400cc. Then in 1985 a 750cc GSX-R was introduced and followed by an 1100cc version in 1986. If the 750cc bike was a fast and capable race-bike for the street, the 1100 was an exercise in raw power and excess. A bit heavier than the 750, at a claimed 435 lbs, but with considerably more power (130 hp stock) and torque. Previous to both of these models,

The first GSX-R of 1984 was a breakthrough model and the closest that any Japanese manufacturer had yet come to building a “race bike with lights”. Throughout the 1970s the big four Japanese manufacturers had built bikes with a similar architecture: steel double loop frames, air-cooled inline fours with either SOHC or DOHC configurations suzuki hayabusa, suzuki, suzuki gsxr wallpaper, Motorcycle wallpapers, suzuki wallpaper hd

(Motorcycle)Suzuki PE series Motorcycle
In the specialised Enduro field, the USA market was dominated by machines by Penton (KTM), Rokon, Husqvarna, Maico, CZ, Can-Am and others. Suzuki saw this as an area in which they could compete. In 1975, Tosh Koyama and T. Shigenoya at US Suzuki asked John Morgan to provide the factory with information about Enduros and Enduro motorcycles. He then met with a group of Suzuki’s factory engineers to discuss in detail. Suzuki were also working with Graham Beamish (their UK importer), and in Autumn of 1975, undertook to take the upcoming 1977 RM250B motocrosser and add the appropriate engine, lighting and suspension changes to allow this motocross racer to run over short stretches of public roads during enduros. This was a keenly priced, well performing machine for the period. The British Trophy team entered 3 of the new PE250B into the Austrian ISDT of September 1976 and carried off 3 gold medals, despite repeated stops to allow the machines to cool.

The initial 1977 PE250B proved rugged, well made and docile. The engine was effectively the 5-speed RM series motocross engine, with altered gearing, porting and a heavier flywheel, which produced only 28HP but had broader power and outstanding torque. This proved highly competitive and popular in all countries Motorcycle wallpapers#SuzukiSuperbike #SuzukiGsxr #SuzukiMotorcycles #SuzukiWallpaper #SuzukiHayabusa

(Motorcycle)Suzuki RG250 Gamma Motorcycle
Mk2 (1985): Revised front fairings, mudguard and colour scheme and a slightly shorter wheelbase (from 1385 mm to 1360 mm)

Mk3 (1986-1987): Introduction of Suzuki’s AEC system (Automatic Exhaust Control). This gave the bike a higher (around 49-50+hp) power rating.

(AEC system: Same idea as the now standard power valve design, but using a ‘butterfly flap’ to open and close an addition chamber on the cylinder head (open @ low RPM, closed at higher). This effectively expands the exhaust system at low RPM, to allow the exhaust to be tuned for high RPM. The AEC system opens at around 7500 RPM)

Mk4: (1987): There was also a very short-lived Mk4 version created for the Japanese home market, which had larger front discs, thicker tyres and larger diameter front forks. This model was never exported.

The RG250 Gamma was replaced by the RGV250 Gamma (V-Twin) in 1988
