I use Michelin Airstop tubes. An internet shop here had sale last year so I have some for front and rear. Standard as well as thicker. Assembly mistakes must have extra, redo and forget ;)

The valve tool was often shipped with tubes in the 80's, other side of the metal cap. Today only plastic caps with no tool.

It must be possible to reuse if used 5000-6000km and less than a year?
If it survive the tire removal ;)

It looks like American Moto Tire has the Michelin Airstop tubes

Over on the Royal Enfield forums the Michelin Airstop tubes are thought to be the best. You can get them at Hitchcock's and they ship to the States.

Unfortunately they don't have a rear tire for 150/70. I ended up getting Metzeler HD in the rear, same brand in the front, but standard - and then Drag Specalties 2" and 3.1" rim strips.

You mean the valve caps that had the built in tool?  My buddy had a "collection" of them so I put two on my '67 CB450, looks very period correct...

Yes, I should have saved some.
I have one from many years ago. Use it every time I change tire and tube.

I remember some had a rubber top cap.
I still have a couple in my toolbox in San Diego.....

50 pieces.  That would be enough for all my bikes and then some!

Last couple of tubes I bought had the tool built into the reverse side of the plastic dust cap. Hard plastic and worked ok.
