Now that the snow it flying and my CBR is stripped down and hunkered in the garage , these arrived today, they are

Motorcycle CNC Aluminum Rear Wheel Axles Swingarm Spools With Base for Honda CBR500R PC44 2013 - 2016 CB500F CB500X 2013 - 2014

I have tried some others but the insert part is too big to fit into the swingarm. These will fit and not rotate so after a year of looking I found something the right size. OK scoff if you like, because they are from Aliexpess, but they work and you don't have to go crazy taking off the swingarm. Cheap and easy fix
