Some of the tubes I have been getting lately (Michelin) don't have a threaded valve stem, but the "usual" is to snug them up.
One thing I haven't seen lately is a tire lock, usually found opposite from the valve stem (on the rim), it locked the tire to the rim. Maybe a thing of the past? |

I think that they're still quite common for the woods bike / motocross crowd, but they don't make sense for a dual sport. Tire pressure is generally higher on a DS, so a rim lock becomes redundant. IMHO, they also serve to unbalance a wheel at high speed.
On my XR, I tighten the rim lock securely. I don't want to spin the rim inside the tire (like what happened to my son).

When my son ripped the valve stem off, he was riding a bike with no rim lock, low air pressure and very low gearing. The fix was to install a rim lock from an RM80 (since it was only a 14" rear rim) and increase the pressure to 15psi.
