I like the low profile of those. However, what kind of o-ring is in there? If it's like the silver one, you could probably change it with each tire change. The others you would need to change the whole stem.I like these better than the metal. They are aluminum. I put them on my old 04 ST 1300 in 05, and they are still on there and going strong. I also have them on my 1500 for the past 9 years. Those are still going strong.
You can find them on E Bay also.
Just another option.
yeah, the rubber 90* valve stems are a joke.
that is why I went to the metal 90* valve stems.
makes it easy to check the air pressure, and they never leak.
