Review: Xr650l valve cap orings. - Fits xr650l valve caps!
Review: They are 21" inner tubes - They arrived in a plastic bag. Not sure how smart that was. I installed the first one, it had a hole in it. Did my installation cause it? Probably. Installed the second, same results. I can't blame the tubes though, but they are thin compared to the Kenda Tuff tubes I normally run. Installed a new Kenda tube. and finally got it right. I never got the chance to try either of them though, but I'm sure your results will be better.
