The Ohlins HD540 STX 36 twin shock rear suspension is built for Harley-Davidson FL Touring models such as Road King, Street Glide and Electra Glide. Designed as a rear twin-shock unit, it targets consistent damping control and stable chassis behaviour for touring and spirited road riding. The gas-pressurised design is intended to maintain damping consistency when conditions get demanding.

Ohlins | Made to race, perfected to ride

Ohlins suspension focuses on predictable control and tunability. With the HD540, the emphasis is on improving rear-end stability and feedback while retaining ride quality suited to heavyweight touring platforms.

Who this shock is for

  • Harley-Davidson FL Touring riders wanting a dedicated rear twin-shock solution
  • Owners chasing clearer chassis feedback and improved control through corners and under braking
  • Riders who value tuneable suspension rather than a fixed, one-size setup

Shock design & features

  • STX 36 twin-shock architecture
  • Gas-pressurised damping to support consistent performance and help reduce fade
  • Independent damping circuits intended to support traction and stability

Tuning controls

This model provides external adjustment for compression damping and rebound damping, allowing the rear suspension to be balanced for load, road conditions and riding style.

Before you install

  • Confirm fitment for your specific Harley-Davidson FL Touring variant and current rear suspension configuration.
  • Set sag and damping with your typical luggage/passenger load in mind.
  • After installation, re-check fasteners and clearances once the suspension has cycled through its travel.

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.
