What This Means on the Sportster XL 883 L Superlow

The 883 cc engine sets how quickly weight transfers, and damping has to be matched to that rather than to a class average. This part number spans model years 2011 to 2018; earlier and later generations take different numbers. Short travel and substantial mass are a hard combination: there is little room to absorb anything, so damping quality matters more.

Materials and Manufacture

The damper body is hard-anodised aluminium, which resists both corrosion and the thermal cycling a rear shock lives with. Two units carrying the same part number behave the same way out of the box, which is the whole point of testing each one. Seals are specified for temperature stability rather than for the lowest unit cost.

Damping and Adjustment

Damper stroke comes to 42 mm on this number. Öhlins builds it to 279 mm between the eyes for this chassis. Öhlins uses a 36 mm piston here: more area, lower oil velocity, less heat generated for the same force. The spring is wound to 26 N/mm, and alternative rates are catalogue items. Compression and rebound are adjusted independently, so support under load can be set without changing how fast the wheel returns. Adjustment is by click rather than by feel, so a setting can be written down and returned to.

The STX 36 Blackline in Detail

Blackline in the STX 36 range means black anodising and a black spring, with the 36 mm damping hardware unchanged. Servicing is identical to the standard STX 36. On a retro or a classic twin the black finish often looks more period-correct than gold, and nothing about the damping changes.

Fitment and Compatibility

The fitment stated here is the Harley Davidson Sportster XL 883 L Superlow in its 2011–2018 form, under Öhlins part number HD 757. Because the settings are model-specific, fitting it to a related machine would mean running the wrong specification.

Road Approval

Road approval: a German ABE covers this part on the Harley Davidson Sportster XL 883 L Superlow. Fit it, keep the certificate with the vehicle papers, and nothing further is needed.
