The Ohlins YA888 TTX RT rear shock absorber is designed as a direct-fit rear mono shock upgrade for the Yamaha YZF R1. Built around Ohlins’ TTX architecture, it’s aimed at riders chasing repeatable damping control and clear tyre feedback. The focus is stable chassis behaviour under load and consistent performance through longer, harder sessions.

Ohlins | Made to race, perfected to ride

TTX RT technology is drawn from Ohlins’ racing program and packaged for serious track and fast-road use. This unit is intended to give a broader, more usable tuning window than a basic OE-style shock, with predictable response when you make setup changes.

Who this shock is for

  • YZF R1 riders doing track days or racing who need reliable adjustment range and repeatability
  • Riders addressing rear grip, drive off corners, or chassis stability under braking and acceleration
  • Owners wanting a purpose-built rear mono shock matched to the model application

Shock design & features

This is a gas-pressurised shock with oil and gas separated for consistent damping behaviour and reduced fade as temperatures rise. The TTX layout uses separate damping circuits to help maintain control across a wide range of track conditions and riding styles.

Tuning controls

Adjustability is provided for rebound damping and compression damping, allowing you to balance support, grip and chassis attitude to suit tyres, pace and circuit conditions. These external adjustments are intended to make systematic setup changes straightforward and repeatable.

Before you install

  • Confirm correct fitment for your Yamaha YZF R1 application before installation
  • Check that the fitted spring (listed as 21040-31) suits rider mass and intended use
  • After installation, set sag and baseline adjusters before fine-tuning on track

Serviceability/lifecycle

Like all performance dampers, this unit is designed to be serviced. Regular oil and seal maintenance helps preserve damping consistency and protects internal components, particularly for frequent track use.
