DescriptionThe whole story▼

Öhlins lists part number HD 906 for one machine: the Harley Davidson Sportster XL 1200 CX Roadster built 2016–2018. Rear grip is decided by how the damper controls load transfer, not by the tyre alone.

Key Features

  • Built to 336 +10/-0 mm installed length
  • Damping piston: 36 mm
  • 77 mm of damper stroke
  • Spring rate prog.16-26 N/mm, set against this machine's weight
  • Spring part number 00480-02 fitted
  • Built for the Harley Davidson Sportster XL 1200 CX Roadster (2016–2018); fits without modification
  • Adjustable overall length for ride-height and geometry changes
  • Gas-pressurised monotube damper with the reservoir integrated into the body

Construction and Material Quality

The unit is rebuildable: seals, shims and oil are catalogue items, not a reason to buy a new one. Machining, anodising, assembly and testing all happen in the same building rather than across a supply chain. Every Öhlins dealer can re-valve the unit, because the shim stack is a documented, serviceable assembly.

What This Means on the Sportster XL 1200 CX Roadster

The 1200 cc engine sets how quickly weight transfers, and damping has to be matched to that rather than to a class average. Öhlins covers the 3-year production run of this generation with a single part number, which means the mounting and the linkage stayed unchanged across it. A cruiser is often ridden two-up with luggage, which is the load case the standard suspension rarely handles well.

About the STX 36 Twin Range

Retro and classic machines often carry a pillion regularly, which is why the preload range matters more here than on a sportbike. Both units are supplied as a matched pair with the same part number and the same valving. Classic and retro machines with twin rear shocks are usually let down by their dampers long before their frames.

How It Behaves on the Road

Öhlins quotes 77 mm of damper stroke for this fitment. The fitted spring rate is prog.16-26 N/mm, chosen against the Sportster XL 1200 CX Roadster's weight distribution rather than a catalogue average. Length is specified as 336 +10/-0 mm, adjustable at the unit without removing it. Spring part number 00480-02 is a separate catalogue item, so a rate change is inexpensive. Compression and rebound are adjusted independently, so support under load can be set without changing how fast the wheel returns. A single click produces a change most riders can detect, which is not true of every adjustable damper.

Fitment and Compatibility

What follows applies to the Harley Davidson Sportster XL 1200 CX Roadster built 2016–2018, which is the machine HD 906 is listed for. Because the settings are model-specific, fitting it to a related machine would mean running the wrong specification.

Road Approval
