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

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.
