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.
