What It Is
Dimensionally this is 18 mm, 50 mm, 26.5 mm, which is how it is told apart from the rest of the range. Cross-section is as important as diameter: an O-ring that is too thin will not seal at pressure. A weeping damper almost always starts here. A leaking damper is not a cosmetic problem: it is a damper that has stopped controlling the wheel.
Why the Original
Öhlins manufactures service parts on the same lines as production parts — there is no second quality. The alternative to a service part is usually a new damper, which is why this catalogue exists. We can check the number against the Öhlins exploded view before you order — just ask. Tell us the damper's model designation and year and we will match the number for you.
How to Be Sure It Fits
05122-13 is the Öhlins number for this position — the same one printed in the service documentation. Öhlins states inner diameter 18 mm, outer diameter 50 mm, thickness 26.5 mm for this number, and those figures are the deciding ones. Öhlins recommends replacing seals whenever the unit is opened, not only when it leaks. Öhlins builds the head so the dust seal takes the grit before it reaches the oil seal.
Fitting and Setup Service
Fitting service parts means opening a pressurised unit. As an authorised Öhlins service centre we do that here, with the right tools and a dyno check afterwards — just ask.
