@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

@Calum Okay sounds good, any chance you know the bearing size or can direct me to where i can find them? Many thanks.

Calum

@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.

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.

Calum

@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

kylescave

@Calum Alright no worries, I'll give that a go. Thanks for the advice.

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...

Calum

@spookdog that and by this point they are like a million years old

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?...

Nottsbiker

@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
