context_section_description: GS series – The 1976 GS750 was the first 4-stroke machine released by Suzuki in 20 years. The following year saw Suzuki's first 1-liter machine, the GS1000E, and then in 1979 the GS1000S copy of a Yoshimura GS1000 Superbike.
  Katana – The GSX1100S was released in Europe in 1980; the GSX1000S arrived in the U.S. and Canada later that year as a 1981 model, and revolutionized sportbike styling. A 1982 Katana GS1000SV is on the AMA Motorcycle Hall of Fame's list of "classic bikes" that have been shown in the museum, and was in The Art of the Motorcycle exhibition.
  GSX-R750 was one of the Japanese sport bikes of the 1980s that began the modern race replica era. It had air/oil cooling, light weight, and a powerful engine. The Society of Automotive Engineers of Japan (in Japanese) includes the 1984 Suzuki GSX-R750 as one of their 240 Landmarks of Japanese Automotive Technology, and was in The Art of the Motorcycle.
  Intruder 750 with its OHC 4-valve 45° V-twin engine was the first Japanese cruiser motorcycle (designed to appeal to U.S. riders) in 1985. By 1997, cruiser-style motorcycles would account for nearly 60 percent of the U.S. street-bike market.
  GSX-R1100, related to the GSX-R750, appeared in 1986. The same basic engine would reappear in 1995 to power the Bandit 1200 and remain in production through 2006.
  The DR-BIG aka Desert Express DR800S (in German) off-roader was existent for two model years as the DR750S (in German) until 1990, when its displacement increased to 779cc, still the world largest single cylinder engine in a production motorcycle. Available in Europe through 1999, it was not exported to the U.S. market. Replaced by the V-Strom twin, the DR-BIG has now come full circle as the design inspiration for a 2014 overhaul of the V-Strom 1000 ABS.
  Suzuki RF Series The Suzuki RF series are sport touring motorcycles. They came with three engine variations: 400, 600 and 900 cc. It was in production from 1994 to 1998.
  TL1000S debuted at the 1996 International Motorcycle and Scooter Show as the first Suzuki sport bike with a V-twin engine. This was a liquid-cooled, 90° V-twin, DOHC engine with 4 valves per cylinder, which would be in production through 2012. Although the TL1000S motorcycle ceased production in 2001, the engine would carry on in the TL1000R, the SV1000 and SV1000S, as well as the V-Strom 1000.
  GSX-R600 – a smaller version of the GSX-R750. There were earlier pretenders, but the genuine article arrived in 1997 and has received frequent updates after that.
  Hayabusa (GSX-1300R) was introduced in 1998, and remains Suzuki's flagship sport bike. The 1998 Suzuki Hayabusa is included in the JSAE 240 Landmarks of Japanese Automotive Technology. The development of a second generation Hayabusa for the 2008 model year facilitated the 2007 roll-out of the GSX-1300BK B-King, a highly stylized naked variant.
  SV650 was introduced in 1999 as a budget entry in the naked bike market, and since 2001, offered both naked and fully faired. In 2009 the naked bike version was redesigned and renamed the Gladius in keeping with the sword motif Suzuki established with the Katana. The Gladius motorcycle won a Good Design Award (aka G Mark) from the Japan Institute of Design Promotion.
  GSX-R1000 – This top-of-the-line superbike debuted in 2000, and remains the largest model of the GSX-R series.
  Burgman 650 (AN650) was the largest of a series of urban scooters produced in Japan (marketed as Skywave domestically) as well as in Italy and Spain with engine capacities of 125cc and up. When it appeared in 2002 the 650 was the largest-displacement scooter in the world, and first two-wheel vehicle to have an electrically controlled Continuously Variable Transmission. The Japan Institute of Design Promotion awarded the G Mark Good Design Award to the Skywave 650 in 2003, to the entire Skywave series in 2006 and to the updated Skywave 650LX in 2013.
  Choinori was a lightweight, inexpensive, 50cc scooter and the antithesis of the Skywave 650, but they were introduced at the same time in an effort to increase domestic sales in response to shrinki
