Ohlins SU 789 TTX GP Shock Absorber with Remote Hydraulic Preload Adjuster

The Öhlins SU 789 TTX Shock Absorber represents the pinnacle of suspension engineering — the direct result of over three decades of world championship road racing and more than 100 World Championship titles. Engineered for riders who demand precise, consistent, and fully adjustable suspension performance, the TTX platform delivers a level of tuning flexibility previously reserved for the world's top factory race teams.

Key Features:

• Independent High- and Low-Speed Compression and Rebound Damping: All four damping circuits are fully independent, providing an exceptionally wide range of adjustability with equal force increments across the entire adjustment range — even the shape of the damping curve can be altered to suit any track or riding condition.
• True Compression-Side Damping Technology: Unlike conventional shock absorbers, the TTX generates compression damping through an increase in pressure on the compression side of the piston — not a pressure drop on the rebound side. This fundamentally different approach virtually eliminates cavitation and minimizes the need for high gas pressure in the reservoir.
• Reduced Internal Pressure for Superior Response: Lower internal operating pressures result in outstanding suspension sensitivity and response, even under short-stroke, high-force conditions that would compromise conventional shock performance.
• All Damping Adjustments Affect Oil Flow — Not Displacement: Every preload and rebound adjustment modifies the flow of damping oil through the piston, preserving consistent oil displacement volume and shock piston rod behavior throughout all settings.
• Piggyback Reservoir for Thermal Stability: The external piggyback-style reservoir dramatically improves shock oil cooling, ensuring more consistent damping characteristics over extended sessions and contributing to long-term damper durability.
• Integrated Remote Hydraulic Spring Preload Adjuster: Allows quick and precise spring preload changes without tools, directly from the rider's position or during pit stops.
• 36mm Shock Piston: A larger-diameter piston increases oil flow surface area, contributing to the shock's refined, progressive damping feel and broad adjustability range.

The Öhlins TTX platform is built around the philosophy that every adjustment should produce a predictable, linear change in suspension behavior. Whether dialing in a street setup or chasing lap times on the circuit, the SU 789 TTX gives riders and technicians the tools to find exactly the right balance between comfort, control, and outright performance.
