Early cast wheels are all tubed. I think one of the first tubeless was first gsxr. Not 100%sure on that but do know GS and GSX are tubed. We once ran a 130/70 on a gs1100 shaft but that didn't go well as the tube shredded causing major blow out. Not sure if it was the miss match of tyre or a faulty tube. They were on for only a few miles. Changed the tyre for a correct size one to be on the safe side as it was my wife's bike.
