The Ohlins SU789 TTX RT rear shock absorber is built for Suzuki GSX-R 600 and GSX-R 750 applications where consistent damping control and clear chassis feedback matter. Using a gas-pressurised design, it is aimed at maintaining stable behaviour through repeated hard use. It is a rear mono shock format intended for riders who want more tunability than a basic replacement unit.

Ohlins | Made to race, perfected to ride

TTX RT is part of Ohlins’ track-focused line, developed from race experience and adapted for real-world riding. The design prioritises damping consistency and predictability so setup changes are easier to feel and validate.

Who this shock is for

Suited to GSX-R 600 and GSX-R 750 riders chasing improved control under braking, through direction changes, and on corner exit. It’s also a good fit if you regularly adjust suspension for different tyres, pace, or riding conditions.

Shock design & features

  • Rear mono shock construction for the Suzuki GSX-R chassis.
  • Gas-pressurised architecture to support consistent damping behaviour over extended sessions.
  • TTX RT family design intent aimed at stable, repeatable response.

Tuning controls

This rear shock includes external damping adjusters for compression and rebound, allowing you to tune support and recovery to match your riding style and grip conditions.

Base setup (factory preset)

The SU789 is supplied with a standard fitted spring and a factory baseline intended to get you close on a typical GSX-R setup. Final settings should be confirmed on the bike with correct sag and damping balance for your weight and use.

Before you install

  • Confirm model fitment and any notes relevant to your GSX-R (this unit is listed with a MKI note).
  • Set sag before making damping changes so you’re tuning from a known baseline.
  • Inspect linkage, bearings, and mounting hardware condition during installation.
