No tubes, the 82 had mags that are tubeless. I think my 79 KZ650 D2 does as well. Now I'll have to look. I put Avons on the last two bikes I did for friends and family. Love them. This bike is going up for sale and I got a good price on the Michelin Pilot Activs. I had to take one of them up to 60 lbs pressure before the beads popped in and that was the third try. Not a great idea in retrospect, but there were no casualties.
