    @DTR-NSR I've changed the sleeve bearing that the swing arm bolt goes through if that's what you mean. But i think the movement is coming from the rear shock linkage. where it bolts onto the swing arm? Or is that what you meant.

    I was going to replace the bearings/sleeve in that link however im struggling to find a kit.

    @kylescave Should still be able to get these parts from Yamaha

    90387-164U8 - Part number for the collars

    I'd grab genuine collars then get the bearings from SimplyBearings.co.uk

        @kylescave The bearings will have markings on them that you can use for reference. Simplybearings.co.uk will have them, that's where I got them from.

        https://www.ebay.co.uk/itm/112551533577

        But someone is selling them on eBay for £20

          @Calum Aren't those the swing arm bearings though? They are the ones I've replaced. Or is it possible that the linkage uses the same bearing.

            @kylescave No sorry, they were the swinging arm bearings.

            I vaguely remember doing them on mine. But I can't recall what the sizes were. Just press them out and get the part number from them

                Do a search for :
                ‘Yamaha DT125R rear suspension linkage repair kit’

                It’s not cheap (@ £110) but once done and properly maintained it should last forever. Nobody greases up the nipples on these! That’s why they fail...

                    I've collected all the parts to do the swingarm on my TDR (basically a DTR) from Yamaha / Wemoto and they were horrendously expensive. Bet its cost something daft like two hundred quid or even more for the 125 bits.

                    Strange then that All Balls make a kit for my DT200WR that includes everything across a couple of kits for around a hundred quid!

                      @Nottsbiker

                      Most stolen bike in the UK tax!...

                      If you checked the sizes I bet most bits are the same. The 200 does have an ally swing arm though, no?...

                        @SpookDog yes the 200wr has an aluminum swingarm but so does my 125r (got a dt200r one) and I bet you are correct that loads of bits are the same.

                        Oddly though the the 200 is narrower than the 125 with the linkage mount a different distance from the pivot so would not be a direct swap either
