The Ohlins TTX GP rear shock for the Honda CBR600RR is built around race-developed damping control for consistent feel and feedback on track-focused setups. It uses a separated oil/gas design to help maintain stable damping performance as conditions and temperatures change. Fitment is for a rear mono-shock application.

Ohlins | Made to race, perfected to ride

TTX GP shocks are designed to deliver controlled chassis support and clear tyre feedback under aggressive braking, turn-in and acceleration. The twin-tube architecture is intended to keep damping behaviour consistent through a wide operating range.

Who this shock is for

Suited to riders chasing a more precise rear-end feel for track days and competition use, or anyone wanting broader tuning range than a standard shock. It’s also a good match for riders working with tyre and geometry changes and needing repeatable adjustments.

Shock design & features

This shock is a TTX GP unit with a separated oil/gas layout rather than an emulsion build. The design aims to reduce cavitation risk and keep damping response consistent during long sessions.

Tuning controls

  • Rebound damping adjustment
  • Compression damping adjustment
  • Spring preload adjustment

Before you install

Confirm the supplied spring suits your current rider weight, usage and tyre choice, and set sag before fine-tuning damping. After installation, check clearance through full swingarm travel and recheck fasteners after the first ride.

Serviceability/lifecycle

The HO339 is a fully serviceable performance shock designed for regular maintenance. Periodic servicing helps keep damping consistency and seal condition where it needs to be for track use.
