Many of the bike’s non mechanical design features were dictated concerns other than pure mechanics. The flat front fascia and trade mark dual headlight were incorporated because designers wanted to give the bike the look of an endurance racer and because regulations dictated that the headlight be behind the front axle. The wide plastic panels under the seat where added to hide an unsightly exhaust hanger.The resulting GSXR750 was introduced in 1985 but withheld from the United States due to tariff issues which would have imposed a 39.4 percent tax on each bike because it was over 700ccs. By waiting until 1986, Suzuki saved buyers money as the tax dropped to 24.4 percent. In the intervening year, Suzuki responded to European riders' complaints about the bike’s stability by lengthening the swing arm by an inch.
