Can anyone help me to identify these forks which are from a B40 trials bike I got earlier in the year (Surrey area). I've stripped them to replace the seals which were shot but cannot find anything to suggest a manufacturer.

Stanchions are 32mm diam and 597mm long (parallel along entire length)

There were two 42mm x 32mm x 7mm seals in each fork (is it normal to have 2 seals?)

I'd like to get info on what volume and sort of oil to use in them

Thanks in advance for any replies.

Hi Vlad those forks look like ceriani`s ,they do have two seals per leg.

I would put in about 200cc of 10wt oil as a starting point.

All the best Alan

That's great. Thanks Alan.

Any recommendations for where to get good quality seals and which makes to go for - I don't want to get shoddy budget ones and have to change them again soon!

Cheers!
