DescriptionThe whole story▼

Cylinder head TTX46, Öhlins part number 15080-51. Öhlins turns and hones each tube to a defined roundness, because an out-of-round bore leaks past the piston.

Key Features

  • Original Öhlins service part
  • Öhlins part number 15080-51

What It Is

Öhlins publishes no separate dimension for this position, so the part number carries the identity. A tube that has been bottomed hard often shows a ring mark; that is a reason to replace it. Head and tube are matched by thread and diameter; neither is interchangeable across units. Diameter and length together identify the tube — both are specific to the damper it came from.

Genuine Service Part

Öhlins numbers every position so a workshop can order precisely what it needs, not a whole assembly. Öhlins manufactures service parts on the same lines as production parts — there is no second quality. We can supply the whole position from the drawing rather than the single piece if that is easier. Tell us the damper's model designation and year and we will match the number for you.

Getting the Number Right

The reliable route is the exploded drawing: find the position, read the number, order it — 15080-51 in this case. This position has no published dimension, so the part number is the only reliable identifier. Tubes are replaced when the bore is marked; polishing them out changes the clearance and makes it worse. Length here is the working length, not the overall dimension, which is why two similar tubes are not interchangeable.

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.
