Key Features
- Original Öhlins service part
- Öhlins part number 21664-34
Where It Sits
Öhlins publishes no separate dimension for this position, so the part number carries the identity. A marked inner tube destroys seals repeatedly until it is replaced. Fork parts are specific to the fork, not to the motorcycle it happens to be fitted to. Fork tubes are the structural part of the front end and carry the braking load into the yokes.
Original Öhlins Part
The tolerances here are the ones the unit was assembled to, not a pattern equivalent's interpretation of them. Öhlins publishes dimensions for its service parts so a workshop can verify before it fits. The exploded drawing for your unit names the number; if you do not have it, we do. If you are unsure which number your unit takes, send us the model and serial number of the damper and we will look it up.
How to Be Sure It Fits
If the unit is already open, compare the dimensions below with the part in your hand before ordering 21664-34. This position has no published dimension, so the part number is the only reliable identifier. It houses the compression assembly on most Öhlins cartridge forks. Cartridge tubes sit inside the fork leg and do the actual damping.
Fitting and Setup Service
A damper rebuild is workshop work: it needs the unit dismantled, the shim stack rebuilt in the correct order and the gas charge reset. We are an authorised Öhlins service centre and do exactly that in house — send us the unit or ask us to fit the part with your order.
