DescriptionThe whole story▼

The Öhlins HD 751 exists because the Harley Davidson Sportster XL 1200 XS Forty-Eight Special (2018–2020) needed its own settings, not a shared set. Damping that fades turns a predictable Sportster XL 1200 XS Forty-Eight Special into one that has to be ridden around.

What This Means on the Sportster XL 1200 XS Forty-Eight Special

The 2018–2020 generation kept the same chassis dimensions throughout, so one Öhlins number serves the whole run. Cruisers carry weight low and long, with short suspension travel doing work that a sportbike would spread over twice the stroke. A 1200 cc machine of this type sits in a specific weight band, and Öhlins picks the spring rate for that band rather than for the platform.

The STX 36 Blackline in Detail

On a retro or a classic twin the black finish often looks more period-correct than gold, and nothing about the damping changes. Blackline in the STX 36 range means black anodising and a black spring, with the 36 mm damping hardware unchanged. Twin-shock applications are supplied as a matched pair.

Construction and Material Quality

Production has stayed in Sweden since the company was founded in 1976. Every unit is dyno-tested against the curve held for its part number, not sampled from a batch. Seals are specified for temperature stability rather than for the lowest unit cost.

How It Behaves on the Road

59 mm of stroke is what the Sportster XL 1200 XS Forty-Eight Special's linkage allows, and the shim stack is set for exactly that. Öhlins uses a 36 mm piston here: more area, lower oil velocity, less heat generated for the same force. Öhlins supplies spring 00281-72 or 66419-019 with this unit. Spring rate is 19 N/mm as delivered, which sets static sag for a rider of typical weight. A single click produces a change most riders can detect, which is not true of every adjustable damper. Adjustment is by click rather than by feel, so a setting can be written down and returned to.

Fitment and Compatibility

Part number HD 751 and the Harley Davidson Sportster XL 1200 XS Forty-Eight Special (2018–2020) belong together; other model years take other numbers. Öhlins lists no other machine against this number, so it is not a unit that can be adapted to a neighbouring model.

Road Approval

Road approval: a German ABE covers this part on the Harley Davidson Sportster XL 1200 XS Forty-Eight Special. Fit it, keep the certificate with the vehicle papers, and nothing further is needed.
