DescriptionThe whole story▼

Cylinder head TTX36, Öhlins part number 21871-02. Corrosion inside a tube is terminal: it cannot be honed out without changing the clearance.

Key Features

  • Öhlins part number 21871-02
  • Original Öhlins service part

Where It Sits

There is no measurement to check here — the number and the exploded view identify it. The cylinder is one of the few damper parts that is genuinely wear-limited. The cylinder head closes the working bore and carries the shaft seal and its bushing. Öhlins matches tube and piston as a pair during assembly, which is why the part numbers are specific.

Genuine Service Part

A damper that can be rebuilt is a damper that stays on the bike; that is the whole argument for original service parts. This is an original Öhlins part, not an aftermarket equivalent — the tolerances are the ones the unit was assembled to. If you are between two sizes, send us the measurement and we will check it against the catalogue. Ask us before ordering if you are unsure: a wrong part in a pressurised unit is an expensive lesson.

Identifying the Right Part

Part number 21871-02 is unambiguous; the description alone is not, because Öhlins uses similar wording across sizes. Where no measurement is given, the drawing position is what identifies the part. Most seal kits are built around a specific head design. The cylinder head closes the working bore and carries the shaft seal and its bushing.

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.
