[steering damper "SD RT"]
Ohlins, the most competitive company in the suspension world, has created a steering damper.
This is a true works part that is already the number one installed part in road racing.
The revolutionary oil-returning, high-capacity twin-tube design faithfully transmits the rider's will to the road and minimizes kickback.
As with Ohlins suspension, the smooth beginner characteristics are unparalleled.
6 types of universal series with different strokes and mounting parts for specific models are available as a complete bolt-on kit finished by Ohlins under thorough quality control.

[Beauty, functional beauty, and a sense of ownership condensed into a compact unit]
Ohlins steering damper consists of a piston [A], a shaft [B], an oil passage [C] in parallel, and a cylinder [D] enclosing them, with a damping force adjustment dial [E] at the end of the cylinder.
The adjustment dial is operated in conjunction with the adjustment dial valve installed in the passage to ensure a wide adjustment range, and the oil quantity is controlled by the mechanism part installed on the other side to adjust the change in oil quantity due to thermal expansion.
There are two types of oil quantity adjustment mechanism [F]: the conventional type [Fig. 1] and the new type [Fig. 2].
The feature of the new type is that a spring is used for the adjustment mechanism of the oil volume, so it can cope with internal capacity changes caused by any temperature changes more than before, and generates smooth and stable damping force.
PTFE (Polytetrafluoroethylene) seals and bushings reduce the coefficient of friction for improved friction performance.

■Main shaft
Through-rod main shaft with integral structure.
Because of the unique integrated structure, the superiority in shaft straightness is noteworthy.
Needless to say, it has been polished to the limit by super finishing process.

■Main Tube
Polished inner wall to make the piston rod smoother.
It demonstrates the best combination with piston rings.

■Piston Housing & Piston Rings
Piston housing connected to the main shaft.
This causes the oil in the main tube to be pushed and pulled from side to side by the movement of the shaft.

■Check valve ASSY
This check valve assembly absorbs and controls the pressure generated by a sudden input such as kickback.

■Sub Tubes
Sub tube to catch the oil flowing in from the main tube.
It also serves as the housing for the damping force adjustment jet needle and check valve.

■Damping adjuster
Jet, needle type 16-way adjustment.
Damping is only done here.

■Slide Metal
Two slide metal supporting main shaft with long one-piece structure.
The Ohlins twin-tube steering damper is supported at three points together with the piston ring.

■Oil seal
The conflicting elements of ultra-low friction loss and high windshieldability have been fused together in a high dimension.
The amazingly smooth beginner characteristics would not be possible without this seal.

■Oil Passage
Two oil passages to connect the main and sub twin tubes.

[No.1 Ohlins steering damper.The reason is]
Normally, the steering damper's operating stroke during on-road driving is said to be around 7mm, although it varies slightly depending on the installation position.
With this small stroke volume, it is important to create a steering feel that is faithful to the rider's intention.
And how flexible is the convergence to the disturbance?These two points are the theme of the steering damper.
The twin-tube reflux and integrated through-rod system with Ohlins unique ultra-precision machining will take your riding to the next level.
