The Ohlins TR628 STX 36 Twin shock set is a rear twin-shock replacement for Triumph Bonneville, Scrambler 900 and Thruxton 900 models. Built around Ohlins STX architecture, it is designed to deliver controlled, consistent damping and clear feedback at the rear wheel. This unit uses a gas-pressurised design to help maintain damping performance during sustained riding.

Ohlins | Made to race, perfected to ride

Ohlins road shocks draw on proven damping designs to improve chassis control while keeping ride quality predictable. The TR628 is part of the STX 36 Twin family and is intended for street-focused setups where stability and traction matter.

Shock design & features

  • STX 36 Twin rear shock configuration for twin-shock Triumph fitments
  • Gas-pressurised damping design to help resist fade
  • Separated damping circuits to support accurate control and repeatable tuning

Tuning controls

  • Rebound damping adjustment
  • Spring preload adjustment

Base setup (factory preset)

The TR628 is supplied with an Ohlins-fitted spring (60480-03) and a factory baseline intended to suit typical road use. Final settings should be verified for rider weight, load and tyre choice.

Before you install

  • Confirm fitment for Triumph Bonneville, Scrambler 900 and Thruxton 900 applications listed
  • Inspect mounting hardware and bushings during installation and torque fasteners to the motorcycle manufacturer’s requirements
  • After install, re-check sag and adjust preload and rebound to suit your use

Serviceability/lifecycle

Ohlins shocks are serviceable components. Periodic oil and seal service helps maintain damping consistency and extends component life, particularly if ridden in wet or dirty 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.
