The Ohlins HD145 STX 36 twin shock is a rear suspension upgrade for Harley-Davidson Sportster XL models. Built around Ohlins damping architecture, it’s designed to improve control and consistency over a wide range of road conditions. This unit uses an emulsion-style internal layout and provides external adjustability for fine tuning.

Ohlins | Made to race, perfected to ride

Developed from Ohlins racing know-how and adapted for street use, this twin shock set focuses on predictable damping and stable chassis behaviour. It’s intended to support confident riding without harshness, particularly when load and road inputs change quickly.

Who this shock is for

  • Sportster XL riders wanting more controlled rear suspension than standard.
  • Riders who value tunability for different roads and riding styles.
  • Owners fitting aftermarket parts or carrying varying loads who need adjustable damping and spring preload.

Shock design & features

  • STX 36 twin shock rear configuration for Harley-Davidson fitment.
  • Emulsion-type oil and gas arrangement.
  • Ohlins valving aimed at stable traction and consistent damping feel.

Tuning controls

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

Before you install

  • Confirm fitment for your Sportster XL model and note that this unit replaces the earlier HD 145E application.
  • Set sag and baseline adjustments after installation to suit your load and riding 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.
