Fork overhaul

Product information "Fork overhaul"

Not only the engine and tires are subject to constant wear, but also the fork.

Far too little attention is often paid to this issue. Of course, a fork that has gone 20 TKM or more without maintenance still works, the only question is how well or badly? One thing is certain, wear does not happen overnight, it is a gradual process that you don't notice immediately, you often get used to the deteriorating condition.

The fork contains Teflon-coated brass bushings that guide the inner and outer fork tubes towards each other. Every up and down movement causes wear here. The Teflon coating wears away until it is worn through at some point and the fork tubes only slide on the brass, which of course does not have a positive effect on the wear of the tubes.

This abrasion is then reflected in the fork oil, which eventually becomes quite dirty and can no longer work as well as new oil. If, for example, you pour off the fork oil from a fork that has several thousand kilometers behind it, it is just a black sludge that no longer has much to do with fork oil.

We do not want to spread panic here, but we are of the opinion that there is a need for action! We have already had forks where the bushings were completely worn out after just 10TKM, and some that were still OK after 15TKM. This is due to manufacturing tolerances of the fork tubes, the riding style (many rides on mountain passes with lots of heavy braking manoeuvres naturally put more strain on the fork) and whether a fork stabilizer is installed (this also counteracts wear, as the fork twists significantly less when braking).

Hence our recommendation.

After a good 10 TKM mileage, the fork should be disassembled. Replace the bushings if necessary (usually only the ones on the chrome-plated stanchion wear out. Triumph does not offer the necessary bushings and recommends the complete replacement of the stanchions. (We think this is a senseless waste of money). In any case, change the oil, lube the inner tubes, hollow out the outer tubes, replace the oil seals + dust caps and ideally install sensible ÖHLINS fork springs (cost € 139 per pair) + use the appropriate oil.

Fork overhaul at our premises:

Fork disassembly + reassembly, complete cleaning of the fork, renewal of all worn sliding bushes, lapping of stanchions, hollowing of outer tubes, renewal of oil seals + dust caps, renewal of fork oil (thicker oil for better damping, tried and tested by us and highly recommended!!!).

You can send us your fork, we will carry out the work and send it back to you. Or you can come to our workshop with your bike by appointment and we will carry out all the work. If you wish, you can also wait for your motorcycle. Coffee is included free of charge!

The price varies depending on whether and which bushings or other parts are worn.

Price for a delivered motorcycle: increase of 70 €. If you want to carry out the fork overhaul yourself, you can buy all parts separately from us. You will find everything under the accessory products in this description.
