The Ohlins YA023 STX 46 Adventure rear shock is built for Yamaha WR155 riders who want controlled, consistent suspension behaviour in off-road and enduro conditions. Designed as a purpose-fit replacement unit, it focuses on improving chassis stability and rider comfort when terrain and loads change. External adjustment makes it practical to fine-tune for different trails and riding styles.

Ohlins | Made to race, perfected to ride

Ohlins suspension is developed with a focus on predictable damping control, durability, and repeatable tuning. This Adventure application targets real-world off-road use where compliance and support both matter. The result is a rear shock that helps the bike stay composed through variable surfaces.

Who this shock is for

Suited to WR155 owners riding enduro-style terrain who need better rear-end control than a basic OEM setup typically provides. It also suits riders who regularly change pace, surface, or load and want a shock that can be tuned without disassembly. If you ride long off-road days and prioritise stability and comfort, this unit fits the brief.

Shock design & features

This is an STX 46 Adventure rear shock with a separated oil/gas design to help maintain damping consistency over extended, rough riding. The architecture is intended to manage heat and keep performance stable when the shock is working hard. Built as a complete unit for the listed fitment, it’s designed for off-road durability and serviceability.

Tuning controls

Adjustment is provided for rebound damping, plus a compression damping adjuster for tailoring support and impact control. A hydraulic spring preload adjuster is also included, making it easier to set ride height and balance when conditions or loading change. These controls allow practical tuning for traction, comfort, and stability.

Before you install

Confirm you are fitting the Enduro version as noted for this model application. Set sag and baseline adjusters after installation, then fine-tune one change at a time to match your tyres, terrain, and riding pace. If you change luggage or carry a passenger, revisit preload and damping to keep the bike balanced.

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.
