Honda XR-50 Fork Bushing

thingiverse

This is a replacement fork bushing for the Honda XR50. It may likely fit other models as well, like the Z50, or CT70, maybe. Of course there's nothing like brand new replacement parts, but, if you don't have them handy, then printing out your own might be a good alternative. I made these bushings out of ABS, and although I was skeptical of how it would react with grease, I am pleased to say we have been using this machine for several months without any problems. I expected the bushings to begin de-laminating as a result of exposure to grease, but so far so good.

Be sure to add plenty of grease upon reassembly. Cleaning up the OD with a coarse file makes for a precise fit.
