Any use?

I took the plunge and purchased these http://www.ebay.co.uk/itm/282163042925 should be here Tuesday or Wednesday.

Still scratching my head a bit as to why this actually happened, as it all started on a trip down to Brighton (120 miles away) to get the seats re-covered, decided to take the curvey route home avoiding motorways. About 2hrs into the return journey the forks basically went like jelly which has resulted in a stanchion having to be replaced because of a piece of plastic disintegrating that does something with the damping.

What mystifies me the most is that the forks have only covered 16,000 miles. So old but hardly used, they had ATF fluid in them, but I cant see that being a cause. The part that broke up did seem a little bit brittle!

If you leave fork oil in too long it can go slightly acidic, depending on the oil type/make, that could have had an effect on the plastic. I think it's best to change fork oil every 3 yrs unless you do bigger miles and then you'd be doing it every 20-30k
I used to have long hair, took acid and went to hip joints. Now I long for hair, take antacid and need a new hip joint

Might have to do mine, only been done once on 100k miles and that was at about 30k  :icon_redface:

I agree but the bike has only covered about 1500 miles since I bought the bike around a year ago and it had not long (6 months prior to buying) had a £400 major service. Which I would have thought they'd of changed the fork oil? Funnily the oil/ ATF in the good leg was as clean as you like, however I can still smell the bad stuff (fish) from the other leg!

The good news is I have a nice pair of 2005 forks, which when I stripped had a set of progressive springs in them, I think were supplied by a company called FTR Suspension, so might even get some history on them. I have left them in for now and will get to try them out on Wednesday (today) but I also have a pair of linear springs if I don't like them.

In the days when I used to use a dealer I paid £350 just have the oil changed and engine shimmed the The TB's balanced and that must be 12+ years ago so I'd doubt very much that the forks where done for a 400 quid service.

No, or me, didnt someone on here recently get quoted around £700 for a big service on a 955?
