The Ohlins YA404 STX 36 rear shock pair is built for Yamaha PG-1 riders chasing better control, traction and stability from their scooter suspension. Developed from Ohlins race-derived damping concepts, it focuses on consistent behaviour under braking, turn-in and acceleration. This is a matched rear twin-shock set designed to improve chassis composure without compromising everyday ride quality.

Ohlins | Made to race, perfected to ride

Ohlins scooter shocks are engineered around stable damping control and predictable response. The YA404 uses the STX 36 scooter platform to deliver a controlled rear end that supports confident riding across varied road surfaces.

Shock design & features

  • Twin rear shock configuration supplied as a pair
  • Oil/gas separated, gas-pressurised design for consistent damping and reduced fade
  • STX 36 scooter architecture aimed at maintaining traction and stability

Tuning controls

  • Rebound damping adjustment
  • Compression damping adjustment

Who this shock is for

  • Riders who want more stability and control than standard suspension, especially when braking and accelerating
  • Owners looking to tune rear suspension behaviour to suit load, tyre choice and road conditions
  • Yamaha PG-1 riders seeking a higher-quality rear shock pair with race-informed damping design

Before you install

  • Confirm fitment for your Yamaha PG-1 and ensure both shocks are installed as a matched set
  • Check clearance around bodywork, exhaust and chain/guard areas before final tightening
  • After installation, set preload and damping adjusters to a sensible baseline, then fine-tune after a short test ride

Serviceability/lifecycle

Ohlins units are designed to be serviceable. Periodic inspection and servicing helps keep damping consistency and seal condition where it should be, particularly for frequent commuting or wet-weather 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.
