The Ohlins HD906 STX 36 Twin rear suspension is a twin-shock unit built for Harley-Davidson Sportster XL models, focusing on controlled damping and consistent chassis behaviour. Based on Ohlins road and race development, it is designed to improve stability and feel without compromising everyday ride quality. It uses a separated oil/gas design to help maintain damping consistency as conditions change.

Ohlins | Made to race, perfected to ride

Ohlins STX 36 Twin shocks are engineered around stable damping control and predictable feedback, aiming to keep the rear tyre working more effectively through varying loads and road surfaces. The HD906 is configured specifically for the Sportster XL platform and rear twin-shock layout.

Who this shock is for

  • Sportster XL riders wanting clearer rear-end support and traction on spirited road rides
  • Owners looking for tunability to match load, roads, and personal preference
  • Riders upgrading ageing or inconsistent rear suspension on twin-shock setups

Before you install
