In 1984 the GS1150ES was the fastest production motorcycle available. The 1150 didn't need any tricks to attain such figures... the power was spread all the way across the range, and was very easy to utilize. New brakes, wheels and tires were also fitted. Power in 1984 was 119bhp@8500rpm, with torque of 81ft/lb's@6500rpm. Wet weight was 557lb's. ”Suzuki only had 8 machines in their 1984 lineup, with only 3 being street bikes. The enlarged engine (from the GS1100's) was placed in an all new chassis, with square tube steel frame and single shock full floater rear suspension.
