DescriptionThe whole story▼

The Harley Davidson Dyna Street Bob 103 FXDB in its 2006–2017 form takes Öhlins part number HD 761. Rear grip is decided by how the damper controls load transfer, not by the tyre alone.

Materials and Manufacture

Two units carrying the same part number behave the same way out of the box, which is the whole point of testing each one. Shafts are hardened and surface-treated so the seal has a consistent surface to run against. The damper body is hard-anodised aluminium, which resists both corrosion and the thermal cycling a rear shock lives with.

Damping Performance

Öhlins quotes 68 mm of damper stroke for this fitment. The 36 mm piston is the same size Öhlins uses across this platform, and the shim stack is what makes it model-specific. The 305 mm length is dictated by the Dyna Street Bob 103 FXDB's own geometry. Öhlins identifies the spring as 00281-66 or 66419-032. A single click produces a change most riders can detect, which is not true of every adjustable damper. Öhlins publishes a baseline setting for each part number, which is the sensible starting point.

What This Means on the Dyna Street Bob 103 FXDB

Short travel and substantial mass are a hard combination: there is little room to absorb anything, so damping quality matters more. This part number spans model years 2006 to 2017; earlier and later generations take different numbers. At 103 cc the Dyna Street Bob 103 FXDB makes enough torque to load the rear hard on corner exit, and the damper has to keep the wheel in contact while that happens.

Where This Sits in the Öhlins Line-up

Servicing is identical to the standard STX 36. Twin-shock applications are supplied as a matched pair. The finish suits classic and retro machines where chrome and black dominate.
