Yep, the Yamaha GTS-1000 was a unique piece, and way, way ahead of its time. Had ABS, electronic fuel injection, and the James Parker designed RADD swingarm front-end, not to mention its aluminum "Omega" frame (which was basically nothing more than a "loop" around each side of the engine lower-end). It used the FZ-1000 five-valve motor, and was really quite quick, but ...
It was heavy (553 lbs., if memory serves me correctly), brutally expensive for a Japanese sport tourer in 1993 and 1994 (over $12,000.00, again, if memory serves ...), and though it handled wonderfully and was more than competitive feature-wise with the other sport touring bikes at the time (BMW's, ST1100's, Concours', etc.), it was perhaps just a bit *too* radical for the sport touring crowd at that time. Having a chain drive hurt it in that market segment, too.
Was introduced in the USA in 1993, but only lasted through 1994, with Yamaha actually having non-current 1994's in inventory for sale on into 1997, I believe. Continued to be sold in Europe right until the 2000 model year if I am not mistaken, and has now been replaced by the FZR1300 sport touring model.
Hope this helps!
