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.

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.
