The Ohlins TR625 STX 36 twin shock is a rear suspension upgrade built for Triumph Bonneville and Thruxton 900 models. It is a gas-pressurised design intended to deliver consistent damping control across varied road conditions. This unit supports rider tuning via external adjustment and is suited to riders who want a more controlled, compliant rear end without changing the character of the bike.

Ohlins | Made to race, perfected to ride

Developed from Ohlins suspension know-how, the STX 36 Twin platform focuses on predictable feedback and stable chassis behaviour. As a twin shock layout for classic-style Triumphs, it’s engineered to integrate cleanly with the original architecture while improving damping quality.

Who this shock is for

  • Triumph Bonneville and Thruxton 900 riders chasing improved control and comfort from the rear suspension
  • Owners who ride briskly on the road and want better composure through corners and over bumps
  • Riders who prefer a twin shock format rather than a conversion to a different rear layout

Shock design & features

  • STX 36 Twin rear shock configuration for classic twin-shock Triumph fitment
  • Gas-pressurised damping system to help maintain consistent damping performance
  • Oil and gas separated architecture (gas-pressurised) for stable damping behaviour during extended riding

Tuning controls

  • Rebound damping adjustment
  • Spring preload adjustment

Before you install

  • Confirm fitment for your exact Triumph Bonneville or Thruxton 900 variant and model year before installation
  • After installation, set sag and confirm clearance through full suspension travel
  • If you change load (pillion/luggage) or riding style, revisit preload and rebound settings

Serviceability/lifecycle

Ohlins shocks are designed to be serviceable. Periodic servicing helps maintain damping consistency and component life, particularly if the bike is ridden frequently or in harsh conditions.
