The Ohlins TR644 STX 36 Blackline shock pair is a rear twin-shock package designed for Triumph Bonneville T100, Bonneville T120 and Street Scrambler models. Built around Ohlins’ STX architecture, it’s intended to improve chassis control and ride quality while suiting classic-style builds. Adjustment is provided so the setup can be matched to rider load and road conditions.

Ohlins | Made to race, perfected to ride

Ohlins suspension is developed with a focus on damping control, consistency and tuneability. The STX 36 Blackline family combines modern internals with a dark, understated finish suited to heritage motorcycles.

Who this shock is for

  • Riders looking to add control and composure to a twin-shock Triumph on real-world roads.
  • Owners who want external adjusters to tailor feel for solo riding, luggage or a passenger.
  • Builders chasing a blacked-out shock look without stepping away from a classic silhouette.

Shock design & features

This is a rear twin-shock pair using the Ohlins STX 36 platform. It uses an emulsion-type damping layout (oil and gas in the same body), packaged for the compact proportions typical of twin-shock fitments.

Tuning controls

  • Rebound damping adjustment
  • Compression damping adjustment
  • Spring preload adjustment

Before you install

  • Confirm the application matches your exact model and year within the Bonneville T100/T120 and Street Scrambler range.
  • Set sag and preload for your typical riding load before making damping changes.
  • After installation, re-check fasteners and clearances through full suspension travel.

Serviceability/lifecycle

Like all performance dampers, these shocks are designed to be serviced to maintain consistent damping over time. Periodic oil and seal service helps keep performance stable, particularly with frequent riding or 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.
