How Öhlins Builds It

Every Öhlins dealer can re-valve the unit, because the shim stack is a documented, serviceable assembly. Two units carrying the same part number behave the same way out of the box, which is the whole point of testing each one. The eyelets carry spherical bearings rather than rubber bushes, so the damper is not fighting its own mounting.

Where This Sits in the Öhlins Line-up

The finish suits classic and retro machines where chrome and black dominate. On a retro or a classic twin the black finish often looks more period-correct than gold, and nothing about the damping changes. The STX 36 in Blackline finish: black anodised body, black spring, 36 mm damping piston.

What This Means on the SPORTSTER XL1200X FORTY-EIGHT

Cruisers carry weight low and long, with short suspension travel doing work that a sportbike would spread over twice the stroke. Öhlins covers the 9-year production run of this generation with a single part number, which means the mounting and the linkage stayed unchanged across it.

Damping and Adjustment

Stroke is 42 mm, which is the travel Öhlins has to work with on this linkage. The unit measures 279 mm installed, which is the dimension the SPORTSTER XL1200X FORTY-EIGHT's linkage expects. Spring rate is 26 N/mm as delivered, which sets static sag for a rider of typical weight. Öhlins specifies 36 mm for the piston on this number. A single click produces a change most riders can detect, which is not true of every adjustable damper. Öhlins publishes a baseline setting for each part number, which is the sensible starting point.

Fitment and Compatibility

What follows applies to the Harley Davidson SPORTSTER XL1200X FORTY-EIGHT built 2010–2018, which is the machine HD 757 is listed for. Nothing about it is generic — the mounting dimensions alone rule out a different model.

Road Approval

Road approval: ABE (Germany). The unit is covered by a German ABE for the Harley Davidson SPORTSTER XL1200X FORTY-EIGHT, so no individual inspection or entry in the vehicle documents is required. The approval document ships with the product.
