Reduce the frequency of fork seal changes by protecting your shiney fork stanchions... These are for a Honda 1992 VFR750, but may well fit lots of other motorcycle models. The cast aluminium forks are 63mm diameter and 22mm tall in my case. Having printed in PLA (no support) I found they were just flexible enough to slip over the ~43mm stanchions without cracking. I then slipped a thin strip of rubber (pond liner) under the plastic and secured with cable ties.Printed with 5mm brim but no support. Installed with small strip of rubber (pond liner from garden center) and cable ties
