The most common problem we see with Ohlins steering dampers is air in the damper. With heavy use air can be dragged in through the seals, collecting in the damper body. Air creates lag in the damper so the bars can move quite a long way before enough damping is generated to slow the movement.
In an accident it is common for the shafts in dampers to bend.
Sometimes this is a big noticeable bend, others it's not noticable until
the steering damper is stripped. A slight bend will drag and stick in
the bushes making the steering heavy.
Regular servicing keeps the damper functioning properly preventing
tank slappers. When servicing Ohlins Dampers we use genuine
spare parts and high quality damper fluid.
