Fork bushes
-
Sorry, didn’t realise oldman was a Jedi name
I know it’s a bitch when you can’t get parts that are readily available for other bikes. I can’t get hold of a diaphragm for the front brake reservoir. Could buy a whole new Chinese replacement, but that’s the point. Doing it right.
I bet there’s a hundred other forks use the same size bush. It’s just knowing what’s what
️ If you’ve got some that you can measure, post the inner and outer diameter and depth of bush. Might be able to find one... -
Apologies for the late reply, time limited. Had a reply from Yamaha with same exploded parts diagram as Fowler's,etc and a frustrating lacklustre reply. Surprising given all my previous contact with them has been excellent.
I sent a reply suggesting they revisit their response and asked for contact details of Yamaha Japan if they were unable to assist further. Received another reply asking for frame no so sent that this eve.
I did also ask about replacing a helmet lock key for the 81mx, given I have the frame and lock number with a negative response, only to purchase a new one (same style as Dt, only difference stamped lock no). May try a Yamaha dealer if all else fails.
Have also sent email to brooks suspension for their advice re bushes and waiting to hear from them.
Will update this post when I can. -
If you have some bottom bushes to hand please measure them. I’d like to know the size...
I’d start by checking out other 41mm forks and see if the bushes are comparable. Even if they need trimming down to fit...It’s like the front exhaust rubber mount. Loads of money for a yam one but pennies for a cx500 one (don’t quote me on the cx500 though!

Hello,
I am also scheduling a fork rebuild on my DT125X, it does not leak at all and in unsprung state it doesn't have any play but if I hold the front brake and spring it in and out, there are centimetres of play and in high speed cornering I feel it unstable. Head bearing was recently replaced, new 32005 and 32006 Koyos instead of the crappy upper SAC 2547-1 which I was like unable to find but eventually I could, but just ended up installing tapered bearings to the upper slot too as it is same size.
I have some questions for like anybody who sees this. I know my forks are Paioli 41mm diameters. Are DTRE and even DTR-s 41mm too as I see it?
I found on yambits that "FBS007" is the upper bushing and is compatible with the RE and Yamaha WR125X which is like the same construction as my DTX so I guess that is same inner/outer/height diameters?
But as like you, I haven't found a lower bushing yet.
I haven't taken the bike apart yet, might wait for the winter season.Thanks for your replies in advance.

@Lorant2
Sorry, couldn't edit anymore.Just found it in another post that they aren't available separately, just with the whole new lower forks. I haven't taken mine yet apart, but if you did, can you pull the bushing below the seal like usual? If so, could you even measure?

So there should be no problem changing that if we find a fitting part
![😕](https://dt125r.co.uk/assets/plugins/nodebb-plugin-emoji/emoji/android/1f615.png?v=jn96li0skqk ":\")
I found the sizes of the outer bushings for the wr125x: OD 45.00mm x ID 41.10mm x W 11.80mm x T 1.95mm
At worst, I will take the forks apart and replace only this if it matches even if there are no inner bushings available.Also there is a hungarian website called oem-parts, on that site I can see the DTX outer/top bushing the same as the WR125X, 1-000-169-691
The inner/bottom bushes are 1-000-188-384 and it is DTX exclusive so I'm pretty shot at this point
Also you can't order any of them, they are unavailable.
For the DTRE, they are 1-000-165-981 and 1-000-137-166 respectively and they match with all the DTR's from the 90's. And they are available for order, lol, here you are:
https://oem-parts.hu/hu/parts/yamaha/motor/2005/dt125re-dt-125-1d03/front-fork
And I'm guessing that the DTRE and DTX forks are same if the DTRE is paioli too. The differences might be in spring, oil quantity, maybe the inner piston hole specifics and the lower fork legs because of the smaller brake disc/wheel shaft size. So the DTR/DTRE/DTX bottom bushing might be the same as well?
-
I'd guess that the RE uses the same forks as the R but might be totally wrong
My TDR forks are also Paoli (sp?) and a total pain to get anything for other than seals which are still available from pattern suppliers
If you can get one out complete you could always have an engineer make some for you from scratch.
Dont forget that 230 Lanza forks would be a good swap into a 125 if in trail mode

How much?

@Nottsbiker £16.89 + £7 DPD delivery

Sounds reasonable - bet I wont find any for the tdr that easily if I need them!
