Why This Machine Needs It

This part number spans model years 2011 to 2016; earlier and later generations take different numbers. The 1200 cc engine sets how quickly weight transfers, and damping has to be matched to that rather than to a class average. A cruiser is often ridden two-up with luggage, which is the load case the standard suspension rarely handles well.

How It Behaves on the Road

With 59 mm of stroke the damping curve has to do its work in a short distance. The damping piston measures 36 mm across, and piston area is what keeps damping force stable once the oil is hot. Rate as supplied is 19 N/mm, matched by Öhlins to this machine rather than to the platform. Spring part number 00281-72 or 66419-019 is a separate catalogue item, so a rate change is inexpensive. Preload is set separately again, and preload is what determines static sag rather than damping. A single click produces a change most riders can detect, which is not true of every adjustable damper.

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. 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.

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. Anodising is hard-coat rather than decorative, which matters on a component exposed to road salt and stone chips.
