With the Suzuki GS 400, the Japanese manufacturer introduced a motorcycle in the fall of 1976, which was soon to become a popular entry-level machine. At the beginning, the motorcycle had 34 hp at 8,500 rpm, but was throttled from May 1977 to an insurance-friendly 27 hp at 7,400 rpm. Deceleration is, in principle, possible, but very complex, because the camshaft has to be replaced. The GS 400, however, is one of the cases in which the motorcycle has also gained some weight because of the throttling, because the usable speed band became significantly larger.
