DescriptionThe whole story▼
Cylinder head TTX36, Öhlins part number 21893-02. A scored bore means lost damping, because the oil bypasses the piston rather than being forced through the shims.
Key Features

- Original Öhlins service part
Where It Sits
There is no measurement to check here — the number and the exploded view identify it. A scored bore means lost damping, because the oil bypasses the piston rather than being forced through the shims. The tube is what the whole damper is built around: everything else references its bore. Öhlins turns and hones each tube to a defined roundness, because an out-of-round bore leaks past the piston.
Original Öhlins Part
Öhlins supports its suspension with individual service parts, which is why a fifteen-year-old damper can still be rebuilt to specification. Öhlins supports units that are decades old, which is why the spare parts list runs to thousands of numbers. Öhlins numbers do not follow a logic you can guess — always read them from the documentation. We can check the number against the Öhlins exploded view before you order — just ask.
How to Be Sure It Fits
21893-02 is the Öhlins number for this position — the same one printed in the service documentation. Öhlins does not publish a dimension here — go by the number and the exploded view. Diameter and length together identify the tube — both are specific to the damper it came from. Öhlins machines the head so the bushing bore is concentric with the seal — otherwise the shaft wears one side.
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.
