Just had same problem with this nylon bush on my 2014 250. Managed to get it out using a blind hole bearing puller as suggested in previous comment, then spent an hour sanding it down to reduce diameter so it would slide inside leg. I cant believe how bad a fit this is,Beta should supply a replacement bush free off charge. Very poor quality control, they must have had to hammer it into place on assembly it was that hard to get out. No wonder the pre load adjustment didnt work.
