The Ohlins TR634 STX 36 Twin shock is a rear twin-shock solution for Triumph Bonneville T100, Bonneville T120 and Street Scrambler models. Built around the STX 36 Twin family architecture, it is designed to deliver controlled damping behaviour with consistent feel across changing road conditions. This unit uses a gas-pressurised damping system to help maintain stability during repeated suspension movement.

Ohlins | Made to race, perfected to ride

Ohlins suspension development focuses on controlled damping, predictable chassis behaviour and tuneability. The TR634 is engineered as a matched pair to suit twin-shock rear layouts while retaining the serviceability expected of an Ohlins unit.

Shock design & features

  • STX 36 Twin rear shock design for twin-shock fitment
  • Gas-pressurised damping system for consistent damping behaviour
  • Designed for a direct fit application on the listed Triumph models

Tuning controls

This shock provides external rebound adjustment to tailor return speed after bumps and weight transfer. It is supplied with a factory base setting intended as a starting point before fine-tuning for load, tyres and riding conditions.

Before you install

When installing, angle the reservoir towards the motorcycle centre-line as noted by Ohlins. Confirm correct orientation and clearance through full suspension travel before riding.

Serviceability/lifecycle

As an Ohlins unit, the TR634 is designed to be serviced to maintain damping performance over time. Periodic inspection and oil service helps keep behaviour consistent, particularly if the bike is used frequently or in harsher 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.
