The STX 36 Blackline in Detail

Twin-shock applications are supplied as a matched pair. On a retro or a classic twin the black finish often looks more period-correct than gold, and nothing about the damping changes. The finish suits classic and retro machines where chrome and black dominate.

Setting It Up for the Road King Special FLHR

The 2017–2019 generation kept the same chassis dimensions throughout, so one Öhlins number serves the whole run. Short travel and substantial mass are a hard combination: there is little room to absorb anything, so damping quality matters more.

Damping Performance

Spring 00280-68 is what ships with the damper; harder and softer rates are available. Rate as supplied is 25 N/mm, matched by Öhlins to this machine rather than to the platform. Damper stroke comes to 92 mm on this number. Piston diameter is 36 mm, which is the figure that decides how hard the oil has to be pushed. The adjuster range is usable end to end rather than only around the middle. Adjustment is by click rather than by feel, so a setting can be written down and returned to.

How Öhlins Builds It

Machining, anodising, assembly and testing all happen in the same building rather than across a supply chain. Öhlins sets a baseline for each part number on the machine it was developed on, so it works before anything is adjusted. Every Öhlins dealer can re-valve the unit, because the shim stack is a documented, serviceable assembly.

Fitment and Compatibility

What follows applies to the Harley Davidson Road King Special FLHR built 2017–2019, which is the machine HD 773 is listed for. It is model-specific rather than universal: length, stroke and valving are all set for this chassis.

Road Approval
