First, big-bore production Katana was developed from Target’s ED-2 concept bike. Changes for production included the addition of a fly-screen and anti- dive forks and slightly revised seat shape. As racing limited bikes to 1000cc with few changes the homologation special GSX1000S came the following year complete with smoothbore carbs and other changes. These are now the most desirable of all Katanas. While in 1983 a 750 version was also produced for the home Japanese market that later evolved into the S3. All revival bikes, including the 250, 400 and later 1100s, were also all based on the original 1100.
