Description
Information

The Ohlins HD643 STX 36 Twin shock set is built for Harley-Davidson Sportster models that need consistent rear suspension control across real-world road conditions. It uses a gas-pressurised design to help maintain stable damping behaviour during extended rides. Independent damping circuits allow you to tailor feel and response to suit your bike and load.

Ohlins | Made to race, perfected to ride

Drawing on Ohlins suspension development, the STX 36 Twin platform focuses on predictable chassis behaviour and clear feedback. The goal is repeatable control rather than harshness, supporting traction and stability as speeds and road inputs change.

Shock design & features

Rear twin-shock configuration for Harley-Davidson Sportster fitment
Gas-pressurised, oil/gas separated architecture to support consistent damping
STX 36 Twin product family construction

Tuning controls

Rebound damping adjustment
Compression damping adjustment

Who this shock is for

Sportster riders wanting more controlled rear-end behaviour under braking and cornering
Owners who value adjustability to suit different roads, tyres and riding style
Riders seeking stable damping during longer rides where heat build-up can affect feel

Before you install

Confirm correct fitment for your specific Sportster model and year
Set spring preload and damping adjusters to a sensible baseline before road testing
After installation, re-check fasteners and clearances through full suspension movement
