The 1981 GS1100E carried over the 1980 bike's 1074 cc 16-valve air/oil-cooled four with few changes, with Suzuki improving the regulator/rectifier during the year. Road tests praised its torque, versatility and adjustable suspension, though the bike was heavy. It arrived into a sales slump, so many were discounted.
