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.

Öhlins Motorcycle Suspension Warranty

New Öhlins motorcycle shock absorbers, front forks and cartridge kits supplied by Teknik Motorsport are covered by the applicable Öhlins manufacturer’s warranty against defects in materials and workmanship.

Teknik Motorsport is an authorised Öhlins Service Centre and administers warranty claims in accordance with the Öhlins warranty conditions. The service intervals below form part of the maintenance requirements for Öhlins products supplied and supported by Teknik Motorsport.

This warranty is in addition to the consumer guarantees that apply under the Australian Consumer Law.

  • Registered motorcycles — non-competition road use Five years, subject to correct application, installation, setup and servicing every: 20,000 km or two years, whichever occurs first.
  • Registered motorcycles — adventure and light off-road use Five years, subject to correct application, spring rate, setup and servicing every: 10,000 km or annually, whichever occurs first.
  • Unregistered or competition motorcycles Two years for eligible Öhlins MX and Enduro products, subject to inspection every ten hours and servicing every: 30 operating hours or annually, whichever occurs first.

Compliance with the applicable service interval is a condition of the Öhlins manufacturer’s warranty. Evidence of servicing may be required when a warranty claim is assessed.

A seal leak, loss of damping performance or internal wear arising after the prescribed service interval has been exceeded will be treated as a service or maintenance issue rather than a manufacturing defect.

Warranty repairs

Öhlins suspension products are designed to be serviced and repaired. Where a warranty claim is approved, the normal remedy is repair of the customer’s original suspension unit using genuine Öhlins replacement parts.

Replacement of a complete shock absorber, fork or cartridge kit is not automatic and would normally occur only where the product has suffered a manufacturing failure that cannot reasonably be repaired. This is at Ohlins discretion. 

Öhlins spare parts and service kits

Öhlins spare parts, seals, bushes, service kits, springs, fluids and individual components are covered only against defects present when supplied.

No fixed age-based warranty applies to wear items, service parts or consumable components. Wear, deterioration, contamination, incorrect installation and damage caused by another component are not manufacturing defects.

Öhlins gives the customer a meaningful five-year warranty on products (Units), provided the suspension is maintained as suspension should be maintained. Teknik supports that warranty locally, can inspect the product properly, and can repair it with genuine parts rather than discarding it.
