The Ohlins HD642 STX 36 Twin shock is a rear twin-shock unit developed for Harley-Davidson Sportster applications where controlled damping and consistency matter. Built around a gas-pressurised design, it aims to keep damping stable as conditions change on the road. This setup is intended for riders who want clearer feedback and more predictable chassis behaviour from the rear end.
