DescriptionThe whole story▼

Piston SD 20, Öhlins part number 02248-02. Rebuilding a piston means keeping the shim order, because the stack is the tuning.

Key Features

  • Öhlins part number 02248-02
  • Original Öhlins service part

Function

There is no measurement to check here — the number and the exploded view identify it. A scored piston face means oil bypasses the shims entirely. Jets meter fixed bleed flow and are sized in tenths of a millimetre. Öhlins machines its pistons rather than sintering them, which is why the port edges stay sharp.

Original Öhlins Part

Öhlins numbers every position so a workshop can order precisely what it needs, not a whole assembly. 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. Order by part number — descriptions repeat across sizes, numbers do not.

How to Be Sure It Fits

Öhlins identifies this position by the number 02248-02 in the exploded view for the unit it belongs to. Öhlins does not publish a dimension here — go by the number and the exploded view. A check valve holds pressure in one direction and opens in the other; a worn one lets damping bleed away. Twin-tube pistons have separate paths for compression and rebound, which is the whole point of the design.

Fitting and Setup Service

Ask us about a full service: as an authorised Öhlins centre we strip, inspect, replace what is worn and set the unit back to its specification.
