For those looking at getting there Sachs refurbed.
Cornering Force at Harrogate do them.
Ive just been over to see them about some other suspension units, and mentioned the Trophy Sachs, and they are more than happy to do the refurb...
Ive found if you need to contact them, its better via email, as there is only 2 chaps there, and they are busy, and sometimes dont answer the phone...
