Key Features
- Original Öhlins service part
- Öhlins part number 01021-04
Where It Sits
Öhlins publishes no separate dimension for this position, so the part number carries the identity. Öhlins uses a piston band rather than metal-to-metal contact, which is what keeps the bore intact. Port area and shim seat geometry decide the damping curve before any adjuster is touched. Needle geometry sets the shape of the adjustable range, not just its size.
Original Öhlins Part
The part number is the contract: it defines material, dimension and finish together. This is an original Öhlins part, not an aftermarket equivalent — the tolerances are the ones the unit was assembled to. Öhlins numbers do not follow a logic you can guess — always read them from the documentation. We can supply the whole position from the drawing rather than the single piece if that is easier.
How to Be Sure It Fits
01021-04 is the Öhlins number for this position — the same one printed in the service documentation. Where no measurement is given, the drawing position is what identifies the part. Öhlins machines its pistons rather than sintering them, which is why the port edges stay sharp. Twin-tube pistons have separate paths for compression and rebound, which is the whole point of the design.
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.
