The Ohlins HD844 STX 36 twin shock is a rear suspension unit developed for the Harley-Davidson XR 1200 in Trophy trim. Built around a pressurised damping design, it is intended to maintain consistent control during sustained hard use. With separate damping circuits, it allows meaningful tuning changes without compromising stability and feel.

Ohlins | Made to race, perfected to ride

Ohlins suspension is engineered to deliver controlled damping behaviour and clear tyre feedback. This twin-shock layout suits the XR 1200 Trophy application where predictable support and repeatable performance are priorities.

Who this shock is for

Designed for XR 1200 Trophy riders who want a more controlled rear end under braking and acceleration, and the ability to tune the bike for different tyres, loads, or riding intensity. It is a fit-for-purpose option when consistency and chassis stability matter more than comfort-oriented damping.

Shock design & features

This is an Ohlins STX 36 twin-shock rear unit using a gas-pressurised, separated oil/gas damping architecture to help reduce fade and maintain damping consistency. The internal layout supports stable damping behaviour during repeated heat cycles and high workload riding.

Tuning controls

The HD844 provides external adjustment for rebound damping and compression damping, along with a spring preload adjustment to set ride height support for rider weight and usage. These controls are intended to help balance traction, support, and stability to suit the XR 1200 Trophy chassis.

Before you install

  • Confirm the shocks are fitted as a matched pair and installed in the correct orientation.
  • Set sag and preload before making damping changes, then adjust one circuit at a time.
  • Check clearance around exhaust, guards, and belt/chain line through full suspension travel.

Serviceability/lifecycle

As a performance Ohlins unit, routine servicing helps keep damping consistent and seals in good condition over time. Service intervals depend on use and conditions, particularly if the bike sees track time or high-heat operation.
