Just a very simple Chain Slider to protect the frame on a 1987 Yamaha TW200. I would assume it would fit other years also, but I don't know that for sure.

This lasted about 6 months that I know of. It was still in good shape when I traded the bike. I used PETG because that's what I had.

I don't have the bike anymore, so I cannot take any more photos of it, but here's a video that should help.
