DescriptionThe whole story▼
When corner-exit stability and high-speed confidence are the difference between a good lap and a great one, the Öhlins SD 027 steering damper delivers the precise, progressive damping force that the Yamaha YZF-R1 RN12 and RN19 demands at the limit — on the circuit and on the road.
Key Features
- 68 mm stroke engineered to absorb tank-slappers and high-speed wobbles before they develop into a handling crisis
- Road and Track type code — tuned for both track-day aggression and demanding road riding in a single unit
- Original mount fitment: integrates directly into the YZF-R1's existing steering geometry without modification
- Universal adaptation capability makes it equally suited to custom builds and dedicated race machines
- Öhlins' renowned adjustability allows damping to be dialled precisely to rider preference, tyre choice and circuit layout
- Sold individually — a direct, focused upgrade for a specific chassis need
Performance on Track
The SD 027 is classified as a Road and Track steering damper, which means Öhlins have calibrated the internal valving to cope with the kind of violent, repetitive steering inputs that emerge when a superbike is ridden hard over aggressive kerbs, mid-corner bumps or high-speed straights. The 68 mm stroke gives the unit enough travel to work through extreme head-shake events while keeping the steering feel natural and communicative — a balance that lesser dampers rarely achieve. Riders campaigning the RN12 or RN19 in club racing will notice the SD 027's influence most acutely at high speeds and during rapid direction changes, where uncontrolled oscillation is replaced by settled, predictable steering.
Installation & Compatibility
Öhlins have engineered the SD 027 to mount in the original steering damper position of the YZF-R1, meaning no brackets need to be fabricated and no chassis drilling is required. The fitment is clean, OEM-matched in mounting geometry, and visually at home on a machine that deserves premium components. The universal adjustment range also opens the door to fitting on lightly modified or custom-built machines derived from the R1 platform, subject to appropriate bracket selection.
