The Ohlins HD143 is an STX 36 twin rear shock kit designed for Harley-Davidson Sportster XL models. Built around a pressurised damping layout, it delivers consistent control as conditions and loads change. This set is aimed at riders wanting more support and clearer feedback than a basic twin-shock setup.

Ohlins | Made to race, perfected to ride

Ohlins road and custom applications draw on proven damping architecture and careful valving control. The focus is predictable response, repeatability and a broad tuning range for real-world riding.

Who this shock is for

  • Sportster XL riders upgrading the rear end for improved chassis control and stability
  • Riders who want tuning capability to suit different roads, pace and load
  • Owners seeking a matched twin-shock solution from the Ohlins STX 36 family

Shock design & features

This is an oil/gas separated, pressurised twin-shock arrangement rather than an emulsion design. The pressurised layout helps maintain damping consistency and reduces the tendency for fade during extended riding.

Tuning controls

The HD143 provides rebound damping adjustment and compression damping adjustment, allowing you to balance support, comfort and grip for your riding conditions. Adjustability also helps when changing tyres, load, or overall ride feel.

Before you install

  • Confirm fitment to your specific Harley-Davidson Sportster XL model and any accessories that may affect clearance.
  • Set sag and verify both shocks are adjusted evenly side-to-side before fine-tuning.
  • If your motorcycle has been modified (ride height, exhaust, guards), check for interference through full suspension travel.

Serviceability/lifecycle

As an Ohlins unit, the shocks are designed to be maintained with periodic servicing to keep damping performance consistent over time. Routine inspection for leaks, bushing wear and spring condition helps protect long-term ride quality.

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.
