The Ohlins YA1492 is a rear TTX 44 shock absorber designed for Yamaha YZ 125/250 2-stroke models. Built around Ohlins’ twin-tube damping concept, it’s intended to deliver consistent control and clear chassis feedback across changing track conditions. This unit is supplied without a spring, allowing spring selection to suit rider weight and use.

Ohlins | Made to race, perfected to ride

TTX architecture is focused on stable damping behaviour and repeatable adjustment changes. It’s a popular format in motocross and enduro where traction, braking support and mid-corner stability matter.

Who this shock is for

  • Riders chasing more controlled rear-end behaviour under braking and acceleration
  • Those who want a shock that can be tuned for different tracks and conditions
  • Owners who prefer selecting a dedicated spring rate rather than using a one-size setup

Shock design & features

  • TTX twin-tube design with oil/gas separation for consistent damping feel
  • Rear mono shock fitment for Yamaha YZ 125/250 2-stroke applications
  • Supplied as a shock unit without spring (spring sold separately)

Tuning controls

  • Compression damping adjustment
  • Rebound damping adjustment

Before you install

  • No spring is supplied; a compatible spring from the specified series is required (see notes)
  • Use the recommended Ohlins shock oil as specified for this unit
  • Set sag and baseline damping after fitment to suit rider weight and conditions

Serviceability/lifecycle

This shock is designed to be serviced and revalved as needed. Routine inspection and periodic oil service help maintain damping consistency, especially with regular motocross use.

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.
