The Ohlins YA340 is a TTX GP rear shock absorber developed for Yamaha YZF R1 fitment where consistent damping control and clear chassis feedback matter. Built around Ohlins’ twin-tube damping architecture, it is designed to keep performance stable as conditions change through a session. It uses a separated oil and gas layout to help maintain damping consistency under sustained load.

Ohlins | Made to race, perfected to ride

TTX GP shocks are designed around stable damping behaviour and predictable response, giving the rider a clearer sense of grip and weight transfer. The layout supports consistent control during heavy braking, direction changes, and corner exits without relying on overly stiff settings.

Who this shock is for

Suited to riders using their Yamaha YZF R1 for track days, racing, or fast road work where setup accuracy is important. It’s a good match if you want a wider tuning window and the ability to tailor rear-end behaviour for tyres, pace, and track surface.

Shock design & features

This is a TTX twin-tube design with separated oil and gas, aimed at reducing cavitation and keeping damping behaviour consistent as the shock works harder. The architecture separates the damping circuits to improve control and repeatability when you’re chasing balance and traction.

Tuning controls

The YA340 provides external damping adjustment for rebound and compression, allowing you to tune support and grip to suit riding style and conditions. These controls help you refine rear stability under braking and acceleration, and balance the bike to your front-end setup.

Before you install

Confirm correct fitment for your exact Yamaha YZF R1 model and year, and set sag and geometry before fine-tuning damping. After installation, re-check fasteners and clearances, then make changes in small steps while keeping notes so you can return to a known baseline.
