Used for Honda XR 50 rear wheel, not XR80. The 1.40/1.60 rim lock fits perfect on the 10" rear wheel. It did not come with a rim lock stock, so this was a nice addition by simply drilling a hole. Thanks!

It's some foam. It should really come with a rimlock purchase but it doesn't. I don't know how much it really does, but you're supposed to use it, so I did. Good for peace of mind I guess.
