GSX series is the sport travel motorcycle series of Suzuki , powered by a four-stroke engine per cylinder. The first GSX models were launched in 1980, representing the next step in Suzuki's four-stroke road bike series after the dual-valve GS series.
However, in North America, both Suzuki four-valve and two-valve four-stroke road bikes are designated as Suzuki GS motorcycles.
twin-valve engines are still produced in parallel with the four-valve power plant, with larger twin-valve four-cylinder engines getting shaft drive and used to power Suzuki's more travel-oriented bikes such as the GS 850G and GS 1100G, while the GSX series represents performance-oriented.
double valve GS series is Suzuki's first real entry into four-stroke motorcycle . Although Suzuki produced 90cc and 123cc four-stroke single-cylinder road bikes under the Colleda brand in the mid-1950s, Suzuki was primarily a manufacturer of two-stroke motorcycles until 1976. Suzuki's line of road motorcycles was almost entirely two-stroke in the mid-1970s (the strange thing is the Wankel Rotary powered RE-5). The exquisite Suzuki GT series and flagship 750cc water-cooled, positive lubricated, and the three-cylinder two-stroke GT750 are the characteristics of this variety. The GS750, launched in 1976, was Suzuki's first large multi-cylinder four-stroke motorcycle. The GS is the version of Suzuki, known as the General Japanese motorcycle, and this 4-cylinder four-stroke configuration was common among Japanese manufacturers at the time. 63 bhp air-cooled, dual cam, inline four-cylinder GS750 road bike sets mode for the GS/GSX series until the first racing replica was born, 1985 air/oil-cooled Suzuki GSX-R750. The GS750 twin-valve engine demonstrates the influence of Suzuki's long-standing two-stroke design and manufacturing history; the new four-stroke motion pressed together roller bearing crankshafts are commonly used in the bottom end of the two-stroke.
GSX engine's main feature is the transformation from a universal per-cylinder twin-valve semi-spherical combustion chamber with a dome piston design to a per-cylinder four-valve twin-swirl combustion chamber (TSCC) with a flat-top piston design. The TSCC design is essentially a modification of the five-top combustion chamber design and adds a slightly raised ridge along the top of the combustion chamber parallel to the inlet charge airflow. This is to encourage controlled vortex currents of the feed air charge to increase fuel combustion speeds through better flame front propagation. The extrusion area is also provided to the front and rear portions of the combustion chamber. Higher combustion speeds, coupled with reduced heat loss from the shallower combustion chambers produced by relatively narrow valve angles and flat top pistons, means that the GSX engine produces greater power and torque than the GS mill of the same size. Another major difference between
and the first GSX engine is that the valve stem and spring are located inside the cam from the gasket and bucket of the GS engine directly overhead valve to valve drive through the short fork rocker in GSX - due to the reduced angle between the intake valve and exhaust valve, the valve stem and spring are located inside the camshaft . Apart from the head, the GS/GSX engine is also a universal design.
Currently the bicycle series of this name is completely different designs, using derivatives of the former supersports engine, from the early to mid-term GSX-R series.
