By the time when Suzuki for the first time presented its over 1000cc machines, back in the early eighties, the Japanese customers couldn't buy them. The regulations prohibited selling motorcycles with larger than 750cc engines on the domestic market in Japan. No wonder the 1100cc Katanas and other sports muscle bikes of the eighties were selling well over the decade after the model were discontinued in Europe and USA, when the regulations finally were dropped.

Nostalgic design sell quite well in Japan. The new GS1200SS was simply a modern version of the GSX-R1100 from the eighties. A sports-bike for those who dreamed about it when they couldn't get it. It was presented for the domestic market in 2001, available in black or red/black.

The GS12000SS is a full modern bike, although in some details the GS1200SS is still old-fashioned. For example, the speedo and the rev counter were wire-connected instead of electric, like in many other modern bikes. Still, the dry mass of the bike was only 210 kg (462 lbs), making the bike go really fast with its 100 hp engine.

Some minor modifications were made in March 2002 for the second model year. The fuel tank was redesigned and a new cap was mounted. The redisgn of the fuel tank made its capacity to decrease from 20 to 18 liter, and the dry weight decreased from 210 to 209 kg. The new available colors were blue/white and red/black. The price went up with 2,000 Yen.
