2000 KTM LC4 Enduro Fork ID?

Brother-in-law bought a 2000 KTM LC4 400 Enduro. It needs new fork seals - but I am not sure which kit to order from SKF or All Balls or...etc. since it seems 2000 LC4E 400 are listed with the USD forks in the parts fiches, but this bike has the non-USD forks, maybe from '99?

I have a 2000 LC4 640 E just like that one.
They have WP 50mm forks.
I had to order fork seals for it this year.
Munn Racing had them in stock.
Their online parts microfilm was correct.
I usually go into Munn's website through KTMTalk.

Thanks!

I was hoping to get SKF seals for the bike rather than OEM, but OEM will work otherwise. I have oredered from Munn plenty in the past.

When I went to look at the Fiches on Munn - the 2000 LC4 640 shows the same fork as this bike - but the 2000 LC4 400 shows USD forks. Huh!
The LC4 640 does list them as 50mm sliders.

I'm pretty sure those are wp50s extreme. Fantastic forks btw ;)
And another thing about seals, I ordered allballs seals and haven't had an issue, before I mounted them i clipped off a centimetre or so of spring and lubed them well. I also have installed neoprene fork gaitors which prevent all the nasty mud and sand from damaging the seals.

Yeah these are the original seals I am sure as the bike has not really seen that many miles. I'm not surprised they are leaking.

i should hope so,, SKF is a close second to OEM, i think most ppl will agree.

SKF seals are supposed to be lower friction self lubricating material, with better performance. Kind of moot since it seems they don't make a seal for the 50mm WPs
