Function

The published figures are 8 mm, 444 mm. Measure the old part against them before ordering. Öhlins offers several lengths per diameter because stroke differs by model. Öhlins offers shafts in several lengths per diameter because the stroke differs by model. Shafts are not shortened or extended; the length is the specification.

Original Öhlins Part

Suspension is one of the few areas where the original part is genuinely the cheaper decision. A damper that can be rebuilt is a damper that stays on the bike; that is the whole argument for original service parts. If you are between two sizes, send us the measurement and we will check it against the catalogue. Service parts are ordered per piece unless stated otherwise.

How to Be Sure It Fits

21812-17 is the Öhlins number for this position — the same one printed in the service documentation. Öhlins states diameter 8 mm, length 444 mm for this number, and those figures are the deciding ones. The damper shaft carries the piston through the oil and out through the seal head. Shafts are not shortened or extended; the length is the specification.

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.
