DescriptionThe whole story▼

Cylinder head TTX36, Öhlins part number 21896-01. Surface finish is specified in microns, because it decides how quickly the piston band wears.

Key Features

  • Original Öhlins service part
  • Öhlins part number 21896-01

Function

Öhlins publishes no separate dimension for this position, so the part number carries the identity. Head and tube are matched by thread and diameter; neither is interchangeable across units. Wall thickness and bore finish are what let a cylinder hold pressure without deforming under load. Surface finish is specified in microns, because it decides how quickly the piston band wears.

Original Öhlins Part

Öhlins supports units that are decades old, which is why the spare parts list runs to thousands of numbers. The tolerances here are the ones the unit was assembled to, not a pattern equivalent's interpretation of them. If you are between two sizes, send us the measurement and we will check it against the catalogue. Send us the model and serial number of your unit and we will confirm the position before you order.

Identifying the Right Part

If the unit is already open, compare the dimensions below with the part in your hand before ordering 21896-01. Öhlins does not publish a dimension here — go by the number and the exploded view. The cylinder is one of the few damper parts that is genuinely wear-limited. A scored bore means lost damping, because the oil bypasses the piston rather than being forced through the shims.

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.
