The Ohlins YA1992 TTX Flow rear shock is built for Yamaha YZ 125 and YZ 250 2-stroke models where consistent damping and strong chassis control matter most. Developed from Ohlins race technology, it is designed to deliver predictable traction and stability through braking bumps, corner entry and acceleration. This unit is supplied without a spring, allowing the spring rate to be selected to suit rider weight and use.

Ohlins | Made to race, perfected to ride

TTX Flow technology focuses on controlled oil flow through the damping system to help maintain a consistent feel across a wide range of track conditions. The result is a rear shock that supports grip and composure when the pace increases, without relying on vague “one setting fits all” behaviour.

Who this shock is for

  • Motocross riders chasing a more controlled rear end under hard braking and on square-edge bumps
  • Riders who want adjustability to match changing tracks and riding style
  • Owners who prefer to choose the correct spring separately rather than compromise on rate

Shock design & features

This is a gas-pressurised rear shock with separated oil and gas to help maintain damping stability and reduce fade during sustained hard use. The TTX Flow architecture is intended to provide consistent damping response and traction while keeping the chassis settled through rapid load changes.

Tuning controls

Adjustability is provided for rebound damping and compression damping, allowing the shock’s response to be tailored for track roughness, grip level and rider preference. With independent circuits, changes can be made in a controlled way without needing to “chase” settings.

Before you install

  • No spring is supplied; select a suitable spring separately (refer to the noted spring series guidance)
  • Confirm fitment for your exact model and year before installation
  • Use the recommended Ohlins shock oil listed for this unit during service

Serviceability/lifecycle

Ohlins off-road shocks are designed to be maintained and revalved as needed. Regular servicing helps preserve damping consistency and component life, especially in motocross conditions where heat and contamination are high.

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.
