You do realize that the Kawasaki Z1Rtc wasn't a production bike at all, actually neither was the Laverda Jota, the Z1Rtc was a dealer special that had a turbo stuck on a completely standard Z1R and the Jota started life as a Laverda 3C, the Jota was built by Roger Slater, Britain's Laverda importer... Both should be left out of this list... Most people on here are Honda people so it doesn't surprise me that few know about the GS, I knew plenty of guys that had them as soon as they were released, one successfully raced one in its first year, he now owns a Suzuki dealership, Talk to member 750cafe, he has a shed full of GS's....
