Öhlins TTX RT Shock Absorber for Suzuki GSX-R 600/750 (2006-2011) – SU 789

The Öhlins TTX RT shock absorber SU 789 is purpose-engineered for the Suzuki GSX-R 600 and GSX-R 750 (2006–2011), delivering the kind of consistent, predictable damping that transforms everyday road riding as much as the occasional track day. Whether you commute hard or carve weekend B-roads, the TTX RT replaces the factory unit with a unit that holds its performance across the full range of conditions without constant fettling.

Key Features

• TTX Technology prevents cavitation inside the damper, ensuring smooth, fade-free damping lap after lap and mile after mile.
• Pressurised gas damper with a fixed external piggyback reservoir separates oil and gas for stable, consistent response regardless of temperature or riding intensity.
• Adjustable rebound and compression damping lets you fine-tune handling to suit your weight, riding style and road surface without specialist tools.
• Integrated hydraulic spring preload adjuster makes setting ride height and sag straightforward — no C-spanner required.
• 320 mm length (±3 mm adjustment range) with a 63 mm stroke and a 90 N/mm spring rate, dialled specifically for the GSX-R 600/750 chassis geometry.
• German Type Approval (ABE) for Suzuki GSX-R 600 and GSX-R 750 (2006–2010), confirming full road-legal compliance in Germany without individual registration.

Everyday Usability and Real-World Value

Premium suspension components are sometimes dismissed as track-only luxuries, but the SU 789 makes a compelling case for the daily rider. The TTX piggyback design keeps damping oil aerated-free and temperature-stable, so the shock behaves the same on a cold Monday commute as it does on a spirited Saturday run. The hydraulic preload adjuster is particularly welcome here: adjusting for a passenger or a loaded tail bag takes seconds rather than a workshop visit. Over the lifetime of the component, that combination of low-maintenance adjustability and durable Swedish engineering represents outstanding value compared with repeatedly rebuilding or replacing an ageing OEM unit.

Build Quality and Engineering

Öhlins manufactures the TTX RT range in Sweden to the same exacting standards applied to their World Superbike and MotoGP components. The twin-tube TTX architecture places the compression and rebound valving in separate, dedicated circuits, eliminating the cross-talk and pressure spikes that cause conventional mono-tube dampers to feel harsh over successive bumps. The fixed external reservoir adds oil volume, which keeps fluid temperatures lower and sustains consistent damping even under sustained hard use. Spring part number 21040-29 is factory-fitted and matched to the 90 N/mm rate specified for the GSX-R platform.

Fitment and Compatibility

The Öhlins SU 789 is a direct, bolt-on replacement for the following models:

• Suzuki GSX-R 600 (2006–2010) — with ABE approval for Germany
• Suzuki GSX-R 750 (2006–2010) — with ABE approval for Germany

The listing also covers the 2011 model year where the same chassis specification applies. Installation instructions are included; for best results Öhlins recommends fitment by an authorised Öhlins Service Centre.
