teams scrambling to find 1000cc versions. In New Zealand, the wire-wheeled bike won the 1981 National Production Championship, as well as numerous club and national races. The Katanas were rendered obsolete for racing by the release of the 'race replica' Suzuki GSX-R750. There were plans for a 1983-model year Katana 1100SXD to be produced, but it never went into production. One pre-production unit was produced for the then-New Zealand distributor Colemans Suzuki (the bike is still owned by Rod and Carl Coleman); it had slightly higher specifications than the E27-spec SXZ. The number of SXZ bikes built by Suzuki for the New Zealand and South Africa markets was a total of 45 units. Other models Suzuki also produced , versions of the Katana. The 650 had a drive shaft, while the 1984-1986 SE/SF/SG750 is distinguished by having a pop-up headlight. Appearing in 1984 was the Katana 750SE with a pop-up headlight, still using an air-oil cooled engine. These were quite popular, even when their performance was easily outdone by other competitors at the time. The air-cooled GSX Katanas were effectively the last Suzuki sports motorcycles that were 'sporting models' derived from an existing standard model (UJM). The next generation of Suzuki sports bike being the purpose designed oil-cooled GSX-R series in 1985. The Katana name was reused, primarily in the North American and European market, to market the revised Suzuki GSX-F series from the end of the 1980s through to 2006. However, in most other markets around the globe, the GSX600F, GSX750F and GSX1100F are considered to be the direct replacement for the in-house styled GSX550E, GSX750E and GSX1100E sports tourers, and not as direct developments of the Target designed machines. The GSX-F range comprised five basic models split into two general eras: the 1988–1997 GSX600F and GSX750F and the 1988–1993 GSX1100F, followed by the 1998–2006 GSX600F and GSX750F, both of which were heavily restyled compared to their predecessors. These same models were offered in Europe, but without the Katana name, which was absent in Europe from 1986 until the 1999 arrival of a line of 50 cc scooters. The original design ethos reappeared at the 2005 Tokyo Motor Show, when Suzuki rolled out a concept bike called the Suzuki Stratosphere, which heavily incorporated many facets of the original ED1/ED2 designs, albeit combined with a narrow, transversely-mounted inline-six engine. Features used by the design team for the original Katana can
