What It Is
The published figures are 25 mm, 69 mm. Measure the old part against them before ordering. Öhlins machines the eye from the same billet as the body on many units. Thread pitch on end caps is specific to the tube they close. The eye takes the entire load path from wheel to chassis.
Original Öhlins Part
The alternative to a service part is usually a new damper, which is why this catalogue exists. Öhlins manufactures service parts on the same lines as production parts — there is no second quality. Öhlins numbers do not follow a logic you can guess — always read them from the documentation. Order by part number — descriptions repeat across sizes, numbers do not.
Identifying the Right Part
Part number 21780-01 is unambiguous; the description alone is not, because Öhlins uses similar wording across sizes. Check dimension a 25 mm, dimension b 69 mm against what you have removed; a close size is not the same part. The spherical bearing in an end eye lets the damper follow the linkage without side load. End caps seal the unit and carry the adjusters; they are matched to the tube they close.
Fitting and Setup Service
If you would rather not open the damper yourself, we can do it — we are an authorised Öhlins service centre and rebuild these units as a matter of routine.
