Fork care

Front forks need not be the mystery you always thought they were. On a day by day basis little maintenance to the front forks becomes necessary apart from changing the fork fluid already described in the Maintenance section at the beginning of this book.

Some five types of Ceriani sliders have been used, although these have covered only two types of internals. However, for the purposes of this book all the permutations are the same. Come to that, so is the one type of Marzocchi fork. All the forks feature double, or two-way, damping, light down and heavy on rebound. The Marzocchi forks are about an inch longer for the 1200 and late 1000 than the Cerianis so fitted; their use is a result of supply problems.

Look after the stanchions. Try to keep them from becoming scored or even rusty. They will wear over a long period of time but there is no good reason for fork disassembly any further than seal removal and replacement until a very substantial mileage has been run-up. The best protection for the fork stanchions are fork gaiters; and only the 750S and GTL were so fitted at the factory. Obviously these gaiters will fit all other models even with 38mm stanchions. The very earliest 650 and 750 GTs were fitted with fork stanchion shrouds which were very effective. Try to spray the stanchions, even that part hidden by fork shrouds, gaiters and the headlamp brackets, with WD40 so that the metal cannot deteriorate.

Should your machine suffer accident damage, dismantle the forks very carefully and seek expert advice as to whether any parts can be repaired. Ceriani and Marzocchi parts are readily available, and it makes good sense to be safe rather than sorry later.
