The Ohlins HD852 STX 36 twin shock is a rear suspension upgrade designed specifically for the Harley-Davidson XR 1200. Built around Ohlins STX architecture, it focuses on consistent damping control and predictable chassis behaviour. It suits riders who want a more tunable rear end for road and spirited riding.

Ohlins | Made to race, perfected to ride

Developed from Ohlins racing experience, the STX 36 twin shock format is aimed at delivering controlled damping and improved stability from a premium rear shock package. The twin-shock layout is matched to applications that require a direct fit to the standard mounting arrangement.

Who this shock is for

  • Harley-Davidson XR 1200 riders wanting improved control and consistency from the rear suspension
  • Riders who value adjustability to tune feel for their weight, riding style, and road conditions
  • Owners seeking an Ohlins twin-shock solution designed for rear fitment

Shock design & features

This is an oil and gas separated design to help maintain damping consistency during use. The STX 36 construction is intended to provide stable damping behaviour and better support through varying loads and surfaces.

Tuning controls

The HD852 provides external damping adjustment for both rebound and compression, along with spring preload adjustment. This allows you to balance comfort, grip, and chassis control without internal modification.

Before you install

  • Confirm fitment for Harley-Davidson XR 1200 and rear twin-shock configuration
  • Set sag and spring preload for rider weight before fine-tuning damping
  • Check clearance around exhaust and any accessories that may affect shock movement

Serviceability/lifecycle

Ohlins shocks are designed to be serviceable. Periodic servicing helps keep damping performance consistent and supports long-term reliability, especially if the bike sees frequent or demanding use.
