The Ohlins SU039 is a rear shock absorber from the TTX RT family for Suzuki GSX-R 600 and GSX-R 750 models. Built around Ohlins’ race-derived damping architecture, it’s intended for riders who want more consistent control and clearer rear-tyre feedback. This unit uses a gas-pressurised, oil/gas separated design to help maintain damping stability during demanding use.

Ohlins | Made to race, perfected to ride

TTX RT shocks are designed to deliver predictable damping behaviour and a wide tuning window. The focus is stable chassis support under braking and acceleration, with a more controlled transition through corner entry, apex and exit.

Who this shock is for

  • Track-focused GSX-R 600 / 750 riders chasing more precise rear control and repeatable feel.
  • Riders who want greater adjustability than a basic replacement shock.
  • Anyone setting the bike up for slicks or higher-grip trackday tyres and needs a shock that can be tuned around them.

Shock design & features

  • Rear mono-shock configuration.
  • TTX RT architecture with a gas-pressurised, oil/gas separated damping system for consistent performance.
  • Designed to provide stable damping and strong chassis feedback under track loads.

Tuning controls

  • Rebound damping adjustment.
  • Compression damping adjustment.

Before you install

  • Confirm fitment for your exact Suzuki GSX-R 600 / 750 year and linkage configuration before installation.
  • Set sag and establish a baseline with the current tyre and track conditions, then adjust compression and rebound in small steps.
  • Plan periodic servicing to keep damping consistent over time.
