The Ohlins HD145 STX 36 twin shock is a rear suspension upgrade for Harley-Davidson Sportster XL models. Built around Ohlins damping architecture, it’s designed to improve control and consistency over a wide range of road conditions. This unit uses an emulsion-style internal layout and provides external adjustability for fine tuning.
