The Ohlins HD517 STX 46 American V-Twin rear shock is built for Harley-Davidson Softail fitments where controlled damping and ride stability matter. It uses a monotube design with a separated oil and gas layout to support consistent damping behaviour as conditions change. Tuning is straightforward, with external adjusters to match rider preference and load.
