About the STX 36 Blackline Range

The STX 36 in Blackline finish: black anodised body, black spring, 36 mm damping piston. The finish suits classic and retro machines where chrome and black dominate. Servicing is identical to the standard STX 36.

The Dyna Fat Bob FXDF in Particular

Öhlins covers the 11-year production run of this generation with a single part number, which means the mounting and the linkage stayed unchanged across it. Short travel and substantial mass are a hard combination: there is little room to absorb anything, so damping quality matters more.

Materials and Manufacture

Öhlins machines its own critical components instead of buying them in, and the tolerances are where the money goes. Spring and damper are separate part numbers, so a rate change does not mean a new unit. Seals are specified for temperature stability rather than for the lowest unit cost.

Damping and Adjustment

The spring carries Öhlins number 00281-66 or 66419-032 and can be exchanged for a different rate without replacing the damper. Öhlins fits a 33 N/mm spring to this number; riders far from average weight should expect to change it. A 36 mm working face means lower oil speed for a given wheel speed, and lower oil speed means less foaming. Eye-to-eye length is 305 mm, fixed for this application. Preload is set separately again, and preload is what determines static sag rather than damping. The two adjusters do genuinely separate jobs, which is what makes methodical setup possible.

Fitment and Compatibility

The fitment stated here is the Harley Davidson Dyna Fat Bob FXDF in its 2007–2017 form, under Öhlins part number HD 761. Öhlins lists no other machine against this number, so it is not a unit that can be adapted to a neighbouring model.

Road Approval
