Great info.


From the 2019 workshop manual. To grease or not to grease?

Is it a case that the factory ones are teflon coated and replacements are not and need grease?

Iíve always used Belray waterproof grease without an issue. The first time in 2001 I used a spray of WD 40 and destroyed a bearing but read that the Belray worked ok.

Because the 2017- bearing seizes without the audible effects, it goes unnoticed.
What's the difference between the old & new bearings, that prevents the new ones from squeaking & knocking?

Same here, Bel-Ray (blue) waterproof grease is good for the Heim joint. Done it here for years. Read it off KTMTalk I think.

Another observation;

A week ago I pulled the shock out of my 2017 450. I had replaced the heim joint about 20 hours ago. The shock clevis had wear on the inside at the left hand side. I have never noticed this before on previous bikes with many more hours. On closer inspection, the heim joint was not centred in the swingarm. I put it down to drunken mechanicing, figured I would knock it into centre when I got the shock back from the tuner.

I raised this with the tuner, who statedd that he had seen the heim joints moving off centre, especially at Finke and Hattah.

Today I got the shock back and decided to mount that unit in the 2020 300 rather than the 450. The 300 has 21.8 hours and the shock that came out had the same marks on the inside left of the clevis.

Maybe I wasn't so drunk after all?

Why are the heim joints apparently moving left? Has anyone else observed the same?

I'm yet to own a KTM so maybe you need to disregard what I'm saying here-below... I'm often askew.

The up-force mightn't be the same as the down-force; one maybe quick & hard whilst the other is slow & soft?
This might cause it to favour it's lazy side; which would then wear to compound it's laziness even more maybe?

Hazarding a guess I'd say it's to do with torque of the drive chain/chassis flex plus the fact they(shocks) are off centred in the frame/swingarm.
