The Ohlins YA339 TTX GP rear shock absorber is built for the Yamaha YZF R6 and developed from Ohlins racing suspension practice. It is designed to deliver stable damping behaviour and clear chassis feedback under demanding track use. This unit uses a gas-pressurised, oil/gas separated damping layout to help maintain consistency as conditions and temperatures change.

Ohlins | Made to race, perfected to ride

TTX GP is part of Ohlins’ track-focused product family, aimed at riders chasing repeatable feel and control rather than a softer road-biased ride. The design prioritises damping stability and support during hard braking, rapid direction changes and high load exits.

Who this shock is for

  • Yamaha YZF R6 riders primarily using the bike for track days or racing
  • Riders who want reliable feedback to tune grip and balance
  • Setups where consistent damping behaviour lap after lap matters

Shock design & features

This is a rear mono shock built on the Ohlins TTX GP platform. The gas-pressurised, separated oil/gas architecture supports stable damping performance compared with simpler emulsion-style shocks, helping the bike hold a predictable line when the pace increases.

Tuning controls

The YA339 provides external damping adjustments for rebound and compression, allowing you to tune support and traction to suit tyre choice, track surface and riding style. Adjusters are intended for repeatable changes so you can work methodically through setup.

Before you install

  • Confirm fitment for your exact Yamaha YZF R6 model and year before installation
  • Set sag and baseline damping before making larger changes
  • Check clearance and free movement through the full suspension travel after fitting

Serviceability/lifecycle

Like all high-performance Ohlins race-oriented shocks, routine servicing is part of maintaining consistent performance. Regular oil and seal maintenance helps keep damping feel stable and protects internal components over time.
