The Ohlins HD144 STX 36 Twin shock kit is built for Harley-Davidson Sportster XL models that need more controlled rear suspension response. Based on Ohlins STX architecture, it focuses on stability, traction and consistent damping across varied road conditions. Supplied as a rear twin-shock setup, it is designed to give clearer chassis feedback and tunability than a basic replacement unit.

Ohlins | Made to race, perfected to ride

Ohlins suspension is developed from competition experience and refined for real-world use. The HD144 carries that approach into a twin-shock layout suited to the Sportster platform, with an emphasis on predictable behaviour and repeatable setup.

Who this shock is for

  • Sportster XL riders wanting improved composure under braking and through corners
  • Riders who value adjustability to suit load, road conditions and riding style
  • Owners upgrading worn or inconsistent rear suspension with a matched twin-shock package

Shock design & features

This is a gas-pressurised, oil/gas separated design intended to maintain damping consistency. The STX 36 Twin format suits twin rear shock applications and is aimed at providing stable chassis support with improved traction feel.

Tuning controls

The HD144 provides external rebound damping adjustment and external compression damping adjustment, along with spring preload adjustment. These controls let you balance comfort, grip and chassis support to match your riding and typical load.

Before you install

  • Confirm fitment for your exact Harley-Davidson Sportster XL model and year
  • Set sag and preload correctly before making damping changes
  • Make one change at a time and record your settings so you can return to a known baseline

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.
