Got my Ryca boxes yesterday and need to install the tires first but thought these valve stems looked pretty neat. (Silver ones) Had a few good reviews. I'm running the 18" Ryca wheels and tubeless Heidenau 4.00-18 tires. http://www.motorcycleanchor.com/tire_valves/index.htm Jeff

They aren't necessary on an 18" wheel....you have plenty of room for a tire inflator and gauge. They would help on the 15" rear wheel that was originally on the bike.

And although they probably don't weigh much....the valve stem side is already the heavy side of the rim most of the time.

And....it looks too much like "bling" for me to use it.

Still need to make sure I mount the tires without marring the rims. Jeff

The problem is that the spokes ferrules and the spoke holes in the wheel don't seal. Some people have been successful at sealing all the spoke holes with various methods, but I wouldn't trust it to stay sealed.

Sounds like you perhaps you are using a spoked rim set up. Your tires may be tubeless, yes, and a spoked rim set up can be made to be tubeless, yes it can.

But, having tried to do "tubeless" on a Savage rear rim you may well wind up having to use a tube before it is all over.

Tubeless tricks on a tube rim means the bead can run out of room in the center well for the tire to make the "go in to the center" movements it has to make on the far side of the wheel to get the bead over the rim on your near, operator side. Extra force may be required to mount the tire on the rim .... beyond what the rim, center relief section, extra rubber down in the center section and the bead can take without getting indigestion with each other.

(rubbing the 1" scar on his left wrist -- scar has shrunk some over the last 4 years to be sure).

Spoked rims CAN be engineered from the factory to be tubeless (check out the rims on a 450, not 250, Honda rebel)
WHY the MC makers still use the idiotic design that requires the use of tubes, and all the problems that entails, is beyond me
Even Harley uses cast wheels on most of their model line FFS, why do we have to put up with the problematic tubed design on a bike in this day and age?

I like the looks of a conventional spoked wheel...works for me. If I were to buy a Royal Enfield or similar new bike....I would be horribly disappointed if the bike had cast wheels.

The rear of my trials bike had a spoked wheel and a tubeless tire. Those bikes only run 4 psi in the rear and they pinch tubes between the tire and rim when you bounce into/off things - so they have a deep center in the rim and a pliable rubber strip that seals off the spoke nipples. Some other bike have spokes that connect to the rim in a way that does not penetrate the rim.

You can mount tubeless tires on a spoked rim - but it requires you to have a tube in the tire as the air will still leak out the spoke nipple holes.

Here is a link to the rear wheel on a 1976 Honda 750 - it shows a spoked wheel, a rim strip, a tube, and a tire.
http://www.hondaofflorence.com/fiche_section_detail.asp?section=2451478&categ...

If you are running tubeless tires and no tube on your Honda - then someone must have done something to seal up all the spoke holes.

I really don't believe that converting rims is a good idea....tubeless rims have a small lip to keep the tire seated on the rim, and spoked rims don't have this lip built into them.

but as mentioned, you can have a spoked rim without the necessity of a tube, like Honda did with the 450 rebel
