The Ohlins YA931 TTX RT is a rear shock absorber developed for the Yamaha YZF R1, built around Ohlins’ race-derived TTX architecture. It’s designed to deliver consistent damping behaviour and clear feedback as pace increases. This unit is a gas-pressurised, oil/gas separated design intended for stable performance over demanding road and track use.

Ohlins | Made to race, perfected to ride

TTX RT shocks bring Ohlins’ twin-tube damping concept into a fitment-specific rear mono-shock package. The aim is controlled chassis movement with predictable grip, especially when the bike is being loaded and unloaded quickly through braking, turn-in and drive.

Who this shock is for

  • YZF R1 riders looking for a higher level of damping control and consistency than a standard rear unit.
  • Track-day and performance road riders who want suspension that responds cleanly to setup changes.
  • Owners who prefer a purpose-built, fitment-specific rear shock rather than a universal solution.

Shock design & features

  • TTX twin-tube damping layout for controlled oil flow and consistent response.
  • Gas-pressurised, oil/gas separated construction to support stable damping under hard use.
  • Designed as a rear mono-shock application for the Yamaha YZF R1.

Tuning controls

This shock includes external compression and rebound damping adjustments, allowing you to tune support and feel to suit your tyres, riding conditions and preferred balance.

Base setup (factory preset)

The YA931 is supplied with a factory baseline setting intended as a starting point. From there, adjust rebound and compression methodically to match your riding style and the bike’s overall chassis balance.

Before you install

Fitment is intended for Yamaha YZF R1 rear mounting. After installation, confirm sag and overall balance with the front end, then test changes one at a time to keep the setup process clear and repeatable.

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.
