Ohlins SD20 004 Universal Motorcycle Steering Damper 140mm Titanium

The Öhlins SD20 004 is a next-generation, universal piston-style steering damper designed for street and supersport motorcycles. Featuring a 140mm stroke and an upgraded Ø20mm piston — 4mm larger than the outgoing SD16 design — the SD20 delivers significantly increased, more consistent damping force and a noticeably smoother feel across the full adjustment range. It is the direct replacement for the previous SD 004 and retains the same mounting measurements despite its more compact body.

At the heart of the SD20 is Öhlins' exclusive cylinder-valve design, developed from technology used in their Factory Racing and EC (electronically controlled) steering damper programs. Unlike a traditional needle valve, this cylinder valve uses a series of precision-drilled holes restricted by an internal edge to balance the force applied to the damper actuator. The result is quicker, more precise adjustment and improved sensitivity at both the low and high ends of the damping range — helping to eliminate tank slappers and erratic handlebar movement whether on the street or track.

The damper body features a titanium anodized finish that complements the signature Öhlins gold and black aesthetic while providing long-term corrosion resistance. As a universal fitment unit, the SD20 004 includes the steering damper body and clamp. Separate, application-specific mounting brackets are available and may be required for certain installations. All Öhlins steering dampers are fully rebuildable using readily available replacement parts.
